摘要

我们通过参数化的纵向相互作用机制对耦合到超导谐振器的量子点混合量子比特进行读出。我们的实验是在量子比特和谐振器频率失谐~10 GHz的情况下进行的，证明纵向耦合可以促进半导体量子比特在电路量子电动力学的“超色散”状态下的操作。

Ultra-dispersive resonator readout of a quantum-dot qubit using longitudinal coupling

We perform readout of a quantum-dot hybrid qubit coupled to a superconducting resonator through a parametric, longitudinal interaction mechanism. Our experiments are performed with the qubit and resonator frequencies detuned by ~10 GHz, demonstrating that longitudinal coupling can facilitate semiconductor qubit operation in the ‘ultra-dispersive’ regime of circuit quantum electrodynamics.
