Surface participation and dielectric loss in superconducting qubits
Chen Wang, Christopher Axline, Yvonne Y. Gao +4
We study the energy relaxation times () of superconducting transmon qubits in 3D cavities as a function of dielectric participation ratios of material surfaces. This surface p…
Multilayer microwave integrated quantum circuits for scalable quantum computing
T. Brecht, W. Pfaff, C. Wang +4
As experimental quantum information processing (QIP) rapidly advances, an emerging challenge is to design a scalable architecture that combines various quantum elements into a comp…
Demonstration of superconducting micromachined cavities
T. Brecht, M. Reagor, Y. Chu +5
Superconducting enclosures will be key components of scalable quantum computing devices based on circuit quantum electrodynamics (cQED). Within a densely integrated device, they ca…
A quantum memory with near-millisecond coherence in circuit QED
Matthew Reagor, Wolfgang Pfaff, Christopher Axline +12
Significant advances in coherence have made superconducting quantum circuits a viable platform for fault-tolerant quantum computing. To further extend capabilities, highly coherent…
Effects of system-bath entanglement on the performance of light-harvesting systems: A quantum heat engine perspective
Dazhi Xu, Chen Wang, Yang Zhao +1
We explore energy transfer in a generic three-level system, which is coupled to three non-equilibrium baths. Built on the concept of quantum heat engine, our three-level model desc…
Nonequilibrium steady state transport of collective-qubit system in strong coupling regime
Chen Wang, Ke-Wei Sun
We investigate the steady state photon transport in a nonequilibrium collective-qubit model. By adopting the noninteracting blip approximation, which is applicable in the strong ph…
