Researchers demonstrate multi-photon state transfer between remote superconducting nodes

Devices that exhibit electrical resonance, have a nominally infinite number of quantum levels.
Over the past few decades, quantum physicists and engineers have been trying to develop new, reliable quantum communication systems. These systems could ultimately serve as a testbed to evaluate and advance communication protocols.
Researchers at the University of Chicago recently introduced a new quantum communication testbed with remote superconducting nodes and demonstrated bidirectional multiphoton communication on this testbed. Their paper, published in Physical Review Letters, could open a new route towards realizing the efficient communication of complex quantum states in superconducting circuits.
