Response of a quantum disordered spin system to a local periodic drive
A. Barış Özgüler, Canran Xu, Maxim G. Vavilov
We consider a one-dimensional spin chain system with quenched disorder and in the presence of a local periodic drive. We study the time evolution of the system in the Floquet basis…
Response to a local quench of a system near many body localization transition
Canran Xu, Maxim G. Vavilov
We consider a one dimensional spin chain with Heisenberg interaction in a disordered parallel magnetic field. This system is known to exhibit the many body localization (MBL)…
High-fidelity qubit measurement with a microwave photon counter
Luke C. G. Govia, Emily J. Pritchett, Canran Xu +4
High-fidelity, efficient quantum nondemolition readout of quantum bits is integral to the goal of quantum computation. As superconducting circuits approach the requirements of scal…
Nonadiabatic Dynamics of a Dissipative Two-level System
Canran Xu, Amrit Poudel, Maxim G. Vavilov
We study the dynamics of a two-level system described by a slowly varying Hamiltonian and weakly coupled to the Ohmic environment. We follow the Bloch--Redfield perturbative approa…
Full Counting Statistics of Photons Emitted by Double Quantum Dot
Canran Xu, Maxim G. Vavilov
We analyze the full counting statistics of photons emitted by a double quantum dot (DQD) coupled to a high-quality microwave resonator by electric dipole interaction. We show that…
Quantum Photovoltaic Effect in Double Quantum Dots
Canran Xu, Maxim G. Vavilov
We analyze the photovoltaic current through a double quantum dot system coupled to a high-quality driven microwave resonator. The conversion of photons in the resonator to electron…
