WebStep 1. Quantum Teleportation begins with the fact that Alice needs to transmit ψ = α 0 + β 1 ψ = α 0 + β 1 (a random qubit) to Bob. She doesn't know the state of the qubit. For this, Alice and Bob take the help of a third party (Telamon). Telamon prepares a pair of entangled qubits for Alice and Bob. WebPSI-Stats has a lower communication overhead compared to the current state-of-the-art circuit-based PSI protocol of Pinkas et al. (EUROCRYPT’19) by a factor of at least 3.9× and consequently has a lower run time than the latter at low network bandwidth settings from our experiments.
