I’m a 50 year old guy working in construction in Quebec. No background in physics or programming — I just play with Qiskit in the evenings for fun after work.
I took a standard 3-qubit quantum teleportation circuit with dynamic error correction (measurements on Alice + classical feedback X/Z on Bob) and tested something that really interested me: where the noise hits matters a lot.
I simulated 4 noise locations:
• Noise everywhere
• Noise only on Alice
• Noise only on the intermediate qubit
• Noise only on Bob (the receiver)
For X (bit-flip), Z (phase-flip), and XYZ (depolarizing) noise — with and without correction.
Here are the results:
(Upload the graph you just sent me here — the one with the 4 plots)
Key takeaways:
• When noise is only on Bob + bit-flip (X), the correction works extremely well — fidelity stays almost 100% even at p=40%
• Correction still helps a lot when noise is on Alice
• Intermediate qubit and especially “everywhere” noise hurt much more
• The location of the noise makes a huge difference
It’s just a hobby project, but I was surprised how important the noise localization is.
Is “noise localization” in quantum circuits something that’s seriously studied in research? Any book, tutorial or next project recommendations for a self-learner would be awesome!

Here is a formal exploration into how the universe might store integrated information over cosmic time scales.
The standard materialist view of consciousness requires sustained information processing, but our baryonic (visible) universe is an incredibly noisy environment. Due to constant thermal photon bombardment, quantum coherence in visible matter is destroyed almost instantaneously.
To model a potential solution, I built Project Phoenix v3.0 in Python—a simulation of an open quantum system using the Dicke-Lindblad Master Equation. I coupled a baryonic subsystem (\bm{A}) to three major dark matter candidates as subsystem (\bm{B}) (Fuzzy Axions, WIMPs, and Dark Photons) using natural units (\bm{\hbar=1}) and anchoring the interaction frequency to the 21cm hydrogen line.
── Key Physics & Observables (See Attached Simulation):
1. The Instantaneous Collapse: As shown in the top row, the concurrence (entanglement between \bm{A} and \bm{B}) drops to zero in less than \bm{0.2\ \tau_A}. The hot, visible universe completely decoheres due to environmental noise.
2. The "Bunker" Effect: Look at the middle-left plot. Subsystem \bm{B}’s reduced Von Neumann entropy (\bm{S_B}) actually decreases back to 0. This mathematically proves that as the visible universe disconnects, the dark matter candidate purifies locally, locking itself into a pristine quantum state.
3. Implications for a Cosmic Consciousness: For the Fuzzy Axion candidate, the coherence time (\bm{\tau}) is calculated at \bm{3.6 \times 10^{12}} years (Row 3, right). Since the current age of our universe (\bm{13.8} billion years) is an infinitesimal fraction of this lifespan, the axion field remains practically untouched by entropy since the Big Bang.
── Conclusion
This framework suggests that dark matter isn't just inert missing mass. It acts as a topologically protected, zero-entropy quantum drive operating on an entirely different cosmic clock—providing the exact physical substrate required to preserve macroscopic consciousness or a foundational "background state" across space and time.
Verified against the No-Communication Theorem (\bm{\Delta\rho_B = 0}). Testable via upcoming SKA 21cm cosmic dawn absorption profiles.
