A General Framework for Gradient-Based Optimization of Superconducting Quantum Circuits using Qubit Discovery as a Case Study
Taha Rajabzadeh, Alex Boulton-McKeehan, Sam Bonkowsky +2
Engineering the Hamiltonian of a quantum system is fundamental to the design of quantum systems. Automating Hamiltonian design through gradient-based optimization can dramatically…
Superconducting coplanar waveguide resonators for low temperature pulsed electron spin resonance spectroscopy
H. Malissa, D. I. Schuster, A. M. Tyryshkin +2
We discuss the design and implementation of thin film superconducting coplanar waveguide micro- resonators for pulsed ESR experiments. The performance of the resonators with P dope…
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…
Protocol for high fidelity readout in the photon blockade regime of circuit QED
E. Ginossar, Lev S. Bishop, D. I. Schuster +1
The driven-damped Jaynes-Cummings model in the regime of strong coupling is found to exhibit a coexistence between the quantum photon blockaded state and a quasi-coherent bright st…
Quantum Non-demolition Detection of Single Microwave Photons in a Circuit
B. R. Johnson, M. D. Reed, A. A. Houck +8
Thorough control of quantum measurement is key to the development of quantum information technologies. Many measurements are destructive, removing more information from the system…
Fast Reset and Suppressing Spontaneous Emission of a Superconducting Qubit
M. D. Reed, B. R. Johnson, A. A. Houck +5
Spontaneous emission through a coupled cavity can be a significant decay channel for qubits in circuit quantum electrodynamics. We present a circuit design that effectively elimina…
