Using Cryogenic CMOS Control Electronics To Enable A Two-Qubit Cross-Resonance Gate
Devin L. Underwood, Joseph A. Glick, Ken Inoue +18
Qubit control electronics composed of CMOS circuits are of critical interest for next generation quantum computing systems. A CMOS-based application specific integrated circuit (AS…
Spectator Errors in Tunable Coupling Architectures
D. M. Zajac, J. Stehlik, D. L. Underwood +9
The addition of tunable couplers to superconducting quantum architectures offers significant advantages for scaling compared to fixed coupling approaches. In principle, tunable cou…
Tunable Coupling Architecture for Fixed-frequency Transmons
J. Stehlik, D. M. Zajac, D. L. Underwood +9
Implementation of high-fidelity two-qubit operations is a key ingredient for scalable quantum error correction. In superconducting qubit architectures tunable buses have been explo…
Imaging Photon Lattice States by Scanning Defect Microscopy
D. L. Underwood, W. E. Shanks, Andy C. Y. Li +3
Microwave photons inside lattices of coupled resonators and superconducting qubits can exhibit surprising matter-like behavior. Realizing such open-system quantum simulators presen…
Beyond Strong Coupling in a Massively Multimode Cavity
Neereja M. Sundaresan, Yanbing Liu, Darius Sadri +5
The study of light-matter interaction has seen a resurgence in recent years, stimulated by highly controllable, precise, and modular experiments in cavity quantum electrodynamics (…
A scanning transmon qubit for strong coupling circuit quantum electrodynamics
William E. Shanks, Devin L. Underwood, Andrew A. Houck
Like a quantum computer designed for a particular class of problems, a quantum simulator enables quantitative modeling of quantum systems that is computationally intractable with a…
Low-Disorder Microwave Cavity Lattices for Quantum Simulation with Photons
Devin L. Underwood, Will E. Shanks, Jens Koch +1
We assess experimentally the suitability of coupled transmission line resonators for studies of quantum phase transitions of light. We have measured devices with low photon hopping…
