|    Every quantum measurement causes the universe to branch                       |
|    All possible outcomes occur in separate parallel branches                     |

| VIOLARIS PROTOCOL - Step-by-Step (Pure Version)                                  |
|                                                                                  |
| Step 1 : Preparation & Measurement                                               |
|    Prepare qubit in superposition |+>                                           |
|    Wigner's Friend performs measurement                                          |
|    → Universe branches into R=0 and R=1                                          |
|                                                                                  |
| Step 2 : Message Encoding                                                        |
|    In Branch R=1 only: Friend writes message μ onto paper register               |
|    Branch R=0 paper register remains blank                                       |
|                                                                                  |
| Step 3 : Memory Uncomputation                                                    |
|    Apply CNOT from paper register P to memory register M                         |
|    → Friend memory erased in BOTH branches                                       |
|                                                                                  |
| Step 4 : Partial Branch Swap (Quantum Crack)                                     |
|    Wigner applies unitary operator U⇌ = XQ × XR × XF                            |
|    → Swaps qubit, observer register, and room label between branches             |
|    → Paper register (message) stays in original position                         |
|                                                                                  |
| Step 5 : Message Readout                                                         |
|    Observer now in Branch R=0 reads paper register                               |
|    → Receives μ written by their counterpart in R=1                              |
|    → Has no memory of ever writing the message                                   |

puts "Introduction"
puts "This program simulates inter-branch communication as described by"
puts "Maria Violaris in the January 2026 paper arXiv:2601.08102v1."
puts "The Many Worlds Interpretation (MWI) of quantum mechanics holds that"
puts "every measurement outcome occurs in a separate branch."
puts "Violaris shows that a special unitary operator, called a quantum crack,"
puts "can route a message across branches without violating standard quantum mechanics."
puts "The Cheshire Cat analogy makes this accessible: the grin (message) crosses"
puts "branches while the cat (observer) stays local in each branch.\n"

puts "Key Idea One: The Violaris Protocol Steps"
puts "Step 1 prepares a qubit in superposition and lets Wigner's friend measure,"
puts "creating an awake branch (R=1) and an asleep branch (R=0) via CNOT entanglement."
puts "Step 2 has the friend in R=1 write message mu onto a paper register."
puts "Step 3 uncomputes the friend memory via a second CNOT from paper P to memory M,"
puts "which erases the friend's local record as described in Violaris Equation 6."
puts "Step 4 applies the partial branch-swap U<=> = XQ x XR x XF from Equation 8,"
puts "where XQ swaps the qubit, XR swaps the observer register, and XF swaps the"
puts "friend register, moving the observer across while the paper stays in place."
puts "Step 5 has the observer in R=0 read mu, receiving knowledge never personally written.\n"

puts "Key Idea Two: The Cheshire Cat Crack Analogy"
puts "Schrodinger's Cat and Wigner's Friend are closely linked thought experiments."
puts "The friend inside the sealed lab sees the cat as definitively awake or asleep."
puts "Wigner outside still describes the whole lab as a quantum superposition."
puts "A quantum crack lets the Cheshire Cat grin - the message content alone -"
puts "cross from the awake branch into the asleep branch under Wigner's control."
puts "For example, the message 'the cat is awake' arrives in the branch where the"
puts "cat is asleep, because U<=> moved the observer, not the paper."
puts "Fidelity equal to 1.0 confirms the message arrives undistorted.\n"

puts "Key Idea Three: Unitarity Is Never Broken"
puts "Every quantum crack operation is reversible and norm-preserving."
puts "No exotic matter, wormholes, or new physics are introduced."
puts "The operation remains entirely within standard linear quantum mechanics.\n"

 START
    Prepare qubit in |+> + W. Friend ready

    W. Friend measures qubit
        → Creates two branches:
            R=0 (asleep / cat asleep)   Paper = blank
            R=1 (awake  / cat alive)  Paper = blank

    In R=1 branch only:
        W. Friend writes message μ on Paper

    Wigner uncomputes memory (erase what friend remembers)
        → Both friends forget they wrote anything

    Wigner performs partial branch swap U⇌
        (swaps friends + qubit + room label, but NOT the paper)

    Friend now in R=0 reads Paper
        → Finds μ from the other branch
        → Never wrote it and has no memory of writing

STOP
    Message successfully transferred across multiverse branches

START: Inter-Branch Message Transfer Protocol (Violaris 2026)

    INITIALIZE
        Prepare qubit Q in |+> state (superposition)
        W. Friend starts in |0> (ready)
        Both branches have blank Paper P and empty Memory M

    CREATE BRANCHES (Step 1)
        W. Friend measures qubit Q
            → Branch R=0 : Cat/Observer sees "asleep" (0)
            → Branch R=1 : Cat/Observer sees "awake"   (1)
        Record room label R for each friend version

    BRANCH R=1 ONLY (Step 2)
        IF friend is in R=1 (awake branch)
            W. Friend thinks of message μ
            W. Friend writes μ onto Paper P
        ELSE (R=0 branch)
            Paper stays BLANK

    UNCOMPUTE MEMORY (Step 3)   ← Critical!
        Wigner erases friend’s personal memory of μ in BOTH branches
        (Friend no longer remembers writing anything)

    PARTIAL BRANCH SWAP (Step 4)   ← The "Quantum Crack"
        Wigner applies U⇌ = X on Q, R, and Friend
            → Swaps the two friends between rooms
            → Paper P does NOT move

  MODULE SIX: Quantum Cracks Model (Violaris 2026)
==================================================================

Maria Violaris's January 2026 'Quantum Cracks' model explores whether a perfect  super-observer (Wigner) could manipulate coherence boundaries between worlds  before full decoherence, transferring limited information across branches via  a theoretical crack in quantum isolation. The model below illustrates perfect  unitary message tunneling under ideal conditions.

 Test 1: Isolation 
Branch isolation enforced => no inter-branch transfer.
{Received message: 0.0 + 0.0i} {Isolation fidelity: 1.00}

 Test 2: Crack Application 
Applying quantum crack control => message tunneled between branches.
Transferred state: 0.7071 + 0.7071i

Test 3: Fidelity Computations 
{Parallel branch message: 1.0 + 0.0i} {Crack fidelity: 1.000}
{Parallel branch message: 0.7071 + 0.7071i} {Crack fidelity: 1.000}
{Parallel branch message: 0.8 + 0.6i} {Crack fidelity: 1.000}

"Decoherence is the process by which quantum branches lose the ability to
interfere with each other due to progressive entanglement with surrounding
environmental particles. Wojciech Zurek developed the modern mathematical
theory of decoherence during the 1980s and 1990s to explain why parallel
branches in MWI appear classically separate to any observer inside a single
branch. The simulation below applies a depth-dependent decay factor that
decreases by 0.04 at each level, starting at 0.92 at depth zero and falling
to 0.72 at depth five. A reader can observe that terminal branches at depth
five carry far less effective coherence than pure MWI branching predicts.
The branch count doubles at each depth while the per-branch probability
shrinks due to both splitting and decoherence, showing how environmental
interaction suppresses quantum interference across all branches."

"Eternal inflation is a cosmological model in which a background inflating
quantum field continues expanding indefinitely while occasionally nucleating
pocket universes called bubble universes. Alan Guth first proposed the broader
idea of cosmic inflation in 1980 to explain the flatness and horizon problems
in standard cosmology. Andrei Linde later demonstrated that the inflation field
can be self-reproducing, making the generation of bubble universes an ongoing
and eternal process. Each bubble that nucleates from the inflating background
inherits a different vacuum energy drawn from the string theory landscape of
possible vacuum configurations. A positive or mildly negative vacuum energy
produces a universe that can expand and support complex structure, while a
strongly negative vacuum energy causes the bubble to collapse. The simulation
generates five bubble universes, assigns each a random vacuum energy in the
range negative one to positive one, records three expansion rates per bubble,
and tests each against a viability threshold of negative 0.5."

Each vacuum state corresponds to a different configuration of the extra spatial
dimensions that string theory requires, and each configuration produces a
different set of physical constants in the resulting universe. The swampland
conjecture is a proposed set of consistency criteria developed by Cumrun Vafa
and collaborators that distinguishes physically realizable string vacua from
mathematically allowed but physically inconsistent ones. Vacuum states with a
cosmological constant below 0.1 in the simulation fail this simplified swampland
criterion. The Cosmic Microwave Background (CMB) is the thermal radiation left
over from the early universe, and each distinct vacuum state would in principle
produce a different CMB anomaly signature visible to future all-sky surveys. The

resolve the strong Charge-Parity (CP) problem in nuclear physics."

claims government researchers constructed a device capable of viewing possible
futures and alternative timelines. The mainstream scientific community does not
recognize Project Looking Glass as a verified or documented technology, and no

module treats the concept strictly as a creative thought experiment rather than
a factual claim, using it as a vehicle to explore the idea of speculative cross-
timeline influence. The module adds an idea absent from the original Looking
Glass narratives: a simulated quantum crack, meaning a temporary breach in the
boundary separating parallel quantum branches, through which a small probabilistic
influence can tunnel from one timeline into another. Quantum tunneling is a real
and well-documented phenomenon in physics, describing the ability of a particle
to cross an energy barrier that classical mechanics would forbid. The simulation
extends this idea speculatively to informational influences tunneling between
parallel timeline branches rather than individual particles crossing a barrier.
A crack probability of 0.15 means tunneling occurs in roughly fifteen of one
hundred independent simulation runs. Setting crack_prob_val to 1.0 forces a
crack on every run, which is useful for testing the crack branch of the code."

  Set RedStack       = branch where R = 0  (asleep room)
  Set BlueStack      = branch where R = 1  (awake room)

-------------------------------------------------------------
INITIALIZE TABLE
-------------------------------------------------------------
  Place RedStack  at fixed space coordinate, at Present level
  Place BlueStack at fixed space coordinate, at Present level
  Set both Paper Chips to blank at the Now layer

-------------------------------------------------------------
BRANCHING RULE
-------------------------------------------------------------
  IF a real quantum measurement occurs
  |   Create one outcome branch for each allowed result
  |   Assign outcome R = 0  to RedStack

  |   Write message M on MessageChip
  |   Store local memory token inside BlueStack
  ELSE (active branch is RedStack)
  |   Leave MessageChip blank
  |   Store no message in RedStack
  END IF

-------------------------------------------------------------
UNCOMPUTE MEMORY
-------------------------------------------------------------
  Erase active memory token from both stacks
  Restore ObserverState to neutral in both stacks
  Preserve MessageChip content unchanged

-------------------------------------------------------------
TIME TRAVEL CHECK
-------------------------------------------------------------
  IF requested move direction is Future
  |   Move observer chip one level UP the stack
  |   Check self-consistency rule

END: POKER-CHIP BRANCH STACK MODEL
-------------------------------------------------------------

DISCLAIMER
  No new chip stack or universe is created by any computer
  math operation, dice roll, or classical random call.
  Only a real quantum measurement inside the lab creates
  a new branch.  Time travel result is Unknown until a
  self-consistency rule confirms or rejects the move.

DEFINE MODEL
Set Branches to a list of chip stacks.
Set SpaceAxis to X, Y, and Z coordinates.
Set TimeAxis to Past, Present, and Future.
Set ObserverState to Little I AM.
Set ExternalState to Big I AM.
Set MessageChip to the paper message carrier.

INITIALIZE TABLE
Create a Red stack for R = 0.
Create a Blue stack for R = 1.
Place each stack at a fixed space coordinate.
Place each stack at the Present level.

BRANCHING RULE
If a real measurement occurs, then
Create one outcome branch for each allowed result.
Assign one outcome to the Red stack.
Assign the alternate outcome to the Blue stack.
Keep the MessageChip in its original horizontal position.
Else
Do not create new branches.

WRITE MESSAGE
If the active branch is Blue, then
Write the message on the MessageChip.
Store the local memory token in Blue.
Else
Leave the MessageChip blank.
Store no message in Red.

UNCOMPUTE MEMORY
Erase the active memory token.
Restore observer memory to a neutral state.
Preserve the MessageChip content.

TIME TRAVEL CHECK
If the requested move is Future, then
Move one level up the stack.
Else if the requested move is Past, then
Move one level down the stack.
If a contradiction appears, then
Reject the move.
Return Unknown.
Else
Stay at the current time level.

DIMENSIONAL TRAVEL CHECK
If the requested move is X, Y, or Z, then
Change space coordinate only.
Do not change branch identity.
Do not change time level.
Else
Keep spatial position fixed.

BRANCH SWAP
If Quantum Crack is activated, then
Swap observer chips between stacks.
Keep the MessageChip fixed in place.
Update branch labels after the swap.

VALIDATE RESULT
If the outcome matches branch history, then
Accept the transfer.
Else if the outcome violates causal order, then
Mark the result invalid.
Else
Return Unknown.
