Normal-metal quasiparticle traps for superconducting qubits
R. -P. Riwar, A. Hosseinkhani, L. D. Burkhart +4
The presence of quasiparticles in superconducting qubits emerges as an intrinsic constraint on their coherence. While it is difficult to prevent the generation of quasiparticles, k…
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 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…
