Distributed Quantum Computing: Remote Gate Teleportation

Real quantum computers are expected to scale not as one giant chip but as a network of smaller quantum processing units (QPUs) linked by entanglement — a distributed quantum computing network. This simulator renders the core primitive that makes that possible: gate teleportation. Node A holds an unknown qubit |ψ⟩; Node B holds one half of a shared entangled pair that was pre-dressed with a target gate U. Running the protocol performs a genuine Bell-basis measurement at Node A, samples one of four equally likely outcomes, animates the two classical correction bits crossing the channel to Node B, and applies the matching Pauli correction there — leaving Node B's qubit in exactly U|ψ⟩ without the two processors ever directly interacting. Live readouts show the sampled Bell outcome, the resulting gate fidelity, and the entanglement/classical-bit resources consumed per run.
