Quantum Lunches: Patrick Leung

Coherent pulse control for quantum memory is experimentally advanced in the optical domain but nascent in microwave quantum circuits. We show how to realize coherent storage and on-demand pulse retrieval within a superconducting circuit by exploiting existing electromagnetically induced transparency technology in quantum circuits. Our scheme employs a linear array of superconducting artificial atoms coupled to a microwave transmission line, which avoids the complexity that arises in the typical approach of transferring microwave pulses between circuits and non-circuit spin-ensembles.
