Heat Conduction and Energy Relaxation in an InAs Nanowire Approaching the Clean One-Dimensional Limit
Subhomoy Haldar, Diego Subero, Mukesh Kumar +5
We investigate heat conduction and energy relaxation in an InAs semiconductor nanowire using a hybrid semiconductor-superconductor architecture. Local electronic temperatures are m…

High-efficiency microwave photodetection by cavity coupled double dots with single cavity-photon sensitivity
Subhomoy Haldar, Harald Havir, Waqar Khan +6
We present a superconducting cavity-coupled double quantum dot (DQD) photodiode that achieves a maximum photon-to-electron conversion efficiency of 25% in the microwave domain. Wit…

Near-Unity Charge Readout in a Nonlinear Resonator without Matching
Harald Havir, Andrea Cicovic, Pierre Glidic +4
In this paper, we present a nonlinear resonator performing the readout of a charge-sensing quantum dot. We show that by driving the resonator in the nonlinear regime, we achieve a…
