Strong coupling between a microwave photon and a singlet-triplet qubit

Single-photon strong-coupling experiment using an InAs nanowire double quantum dot and a magnetic-field-resilient superconducting resonator.

Key Results

Spin-photon coupling $g /2 π = 139 \pm 4$ MHz.
Qubit dephasing $γ /2 π = 116 \pm 7$ MHz and resonator decay $κ /2 π = 19.8 \pm 0.2$ MHz in the arXiv abstract.
