Experimental Quantum Teleportation of Propagating Microwaves

Quantum teleportation (QT) of propagating microwaves: concept and implementation. (A) General concept. (B) Our experimental implementation of QT with propagating quantum microwaves and analog feedforward (also see note S1 for the full technical schematics). Here, an unknown input coherent state is teleported from Alice to Bob by exploiting quantum entanglement characterized by the two-mode squeezing level ST ≲ S. The feedforward signal is generated by the measurement JPAs with the degenerate gain G, in combination with two hybrid rings and a local displacement operation on Bob’s side. The latter is implemented with a directional coupler with the coupling β = −15 dB...
