Unifying quantum heat transfer in a nonequilibrium spin-boson model with full counting statistics
Chen Wang, Jie Ren, Jianshu Cao
To study the full counting statistics of quantum heat transfer in a driven nonequilibrium spin-boson model, we develop a generalized nonequilibrium polaron-transformed Redfield equ…
Suspending superconducting qubits by silicon micromachining
Y. Chu, C. Axline, C. Wang +4
We present a method for relieving aluminum 3D transmon qubits from a silicon substrate using micromachining. Our technique is a high yield, one-step deep reactive ion etch that req…
A coaxial line architecture for integrating and scaling 3D cQED systems
Christopher Axline, Matthew Reagor, Reinier W. Heeres +7
Numerous loss mechanisms can limit coherence and scalability of planar and 3D-based circuit quantum electrodynamics (cQED) devices, particularly due to their packaging. The low los…
Influence of counter-rotating interaction on quantum phase transition in Dicke-Hubbard lattice: an extended coherent state approach
Yongchuan Lu, Chen Wang
We investigate the ground state behavior of the Dicke-Hubbard model including counter-rotating-terms. By generalizing an extended coherent state approach within mean-field theory,…
A Schrodinger Cat Living in Two Boxes
Chen Wang, Yvonne Y. Gao, Philip Reinhold +13
Quantum superpositions of distinct coherent states in a single-mode harmonic oscillator, known as "cat states", have been an elegant demonstration of Schrodinger's famous cat parad…
