Quantum Markov Noise Limits for Data Storage and Communication

Infinite‑time capacity under Markov noise is reached after t ≈ d² ln(d) steps; a globally error‑corrected memory becomes useless after t ≈ n·2^{2n} steps. Read more: getnews.me/quantum-markov-noise-lim... #quantummarkov #quantummemory

Stoichiometric crystal shows promise in quantum memory For over two decades, physicists have been working toward implementing quantum light storage—also known as quantum memory—in various matter systems. These techniques allow for the controlled and reversible mapping of light particles called photons onto long-lived states of matter. But storing light for long periods without compromising its retrieval efficiency is a difficult task.

✨Physicists chase a dream: storing light itself!⏳Mapping photons onto matter could unlock incredible tech, but holding onto that light is the challenge!💡#QuantumMemory
