Multi-Resonator-Assisted Multi-Qubit Resetting in a Network

2016 · arXiv (Cornell University)

We propose a quantum bath engineering method for the initialization of arbitrary number of flux-tunable transmon qubits with a multi-resonator circuit quantum electrodynamics (QED) architecture. Through the application of the microwave drives, we can prepare …

A twofold quantum delayed-choice experiment in a superconducting circuit

2017 · Science Advances

Wave-particle complementarity lies at the heart of quantum mechanics. To illustrate this mysterious feature, Wheeler proposed the delayed-choice experiment, where a quantum system manifests the wave- or particle-like attribute, depending on the experimental arrangement, which …

Experimental Simulation of Open Quantum System Dynamics via Trotterization

2021 · Physical Review Letters

Digital quantum simulators provide a diversified tool for solving the evolution of quantum systems with complicated Hamiltonians and hold great potential for a wide range of applications. Although much attention is paid to the unitary …
