Nonlinear microwave photon-occupancy of a driven resonator strongly coupled to a transmon qubit
Baladitya Suri, Zach Keane, Lev S. Bishop +3
We measure photon-occupancy in a thin-film superconducting lumped element resonator coupled to a transmon qubit at 20mK and find a nonlinear dependence on the applied microwave…
Robust quantum gates for singlet-triplet spin qubits using composite pulses
Xin Wang, Lev S. Bishop, Edwin Barnes +2
We present a comprehensive theoretical treatment of SUPCODE, a method for generating dynamically corrected quantum gate operations, which are immune to random noise in the environm…
Nonlinear oscillators and high fidelity qubit state measurement in circuit quantum electrodynamics
Eran Ginossar, Lev S. Bishop, S. M. Girvin
In this book chapter we analyze the high excitation nonlinear response of the Jaynes-Cummings model in quantum optics when the qubit and cavity are strongly coupled. We focus on th…
Composite pulses for robust universal control of singlet-triplet qubits
Xin Wang, Lev S. Bishop, J. P. Kestner +3
Precise qubit manipulation is fundamental to quantum computing, yet experimental systems generally have stray coupling between the qubit and the environment, which hinders the nece…
Measurements of Quasiparticle Tunneling Dynamics in a Bandgap-Engineered Transmon Qubit
L. Sun, L. DiCarlo, M. D. Reed +9
We have engineered the bandgap profile of transmon qubits by combining oxygen-doped Al for tunnel junction electrodes and clean Al as quasiparticle traps to investigate energy rela…
Circuit Quantum Electrodynamics
Lev S. Bishop
Circuit Quantum Electrodynamics (cQED), the study of the interaction between superconducting circuits behaving as artificial atoms and 1-dimensional transmission-line resonators, h…
