Designing Kerr interactions using multiple superconducting qubit types in a single circuit
Matthew Elliott, Jaewoo Joo, Eran Ginossar
The engineering of Kerr interactions has great potential for quantum information processing applications in multipartite quantum systems and for investigation of many-body physics…
Rare quantum metastable states in the strongly dispersive Jaynes-Cummings oscillator
Th. K. Mavrogordatos, F. Barratt, U. Asari +3
We present evidence of metastable rare quantum-fluctuation switching for the driven dissipative Jaynes-Cummings oscillator coupled to a zero-temperature bath in the strongly disper…
Optimal control of two qubits via a single cavity drive in circuit quantum electrodynamics
Joseph L. Allen, Robert Kosut, Jaewoo Joo +2
Optimization of the fidelity of control operations is of critical importance in the pursuit of fault-tolerant quantum computation. We apply optimal control techniques to demonstrat…
Simultaneous bistability of qubit and resonator in circuit quantum electrodynamics
Th. K. Mavrogordatos, G. Tancredi, M. Elliott +6
We explore the joint activated dynamics exhibited by two quantum degrees of freedom: a cavity mode oscillator which is strongly coupled to a superconducting qubit in the strongly c…
