Quantum Memory Node

Interactive quantum-memory / repeater simulator: write a photon's state into an atomic-ensemble memory, watch its fidelity decay while it waits in storage, and tune write/read efficiency and coherence time to see how often a repeater's entanglement swap actually succeeds.

Quantum memories are the storage devices a quantum repeater relies on: they hold a photon's quantum state in an atomic ensemble long enough for a partner node, possibly kilometers away, to catch up before an entanglement swap is attempted. This simulator fires heralding photons into two memory nodes at slightly different times, decays each stored state's fidelity in real time using an exponential T2 dephasing model, and computes the actual probability that a swap between them succeeds given the write efficiency, read efficiency, coherence time and synchronization delay you choose — the same trade-offs that limit real quantum-network hardware today.

⚙ Under the hood

Write a photon's qubit into an atomic-ensemble quantum memory, watch its fidelity decay while it waits in storage, and tune write/read efficiency, coherence time and sync delay to see how often a repeater's entanglement swap actually succeeds.
