"Remote Superconducting Nodes Achieve Multi-Photon State Transfer"

Researchers at the University of Chicago have demonstrated bidirectional multiphoton communication between remote superconducting nodes, using a new quantum communication testbed with resonators and superconducting qubits. Their study, published in Physical Review Letters, showcases the transmission of complex quantum states representing multiple qubits at the same time, paving the way for efficient communication of more complex quantum states than single photons between two nodes. This advancement could lead to distributed computing, coded quantum information transmission, and further exploration of multi-node communication channels.
