Optimal cooling of a driven artificial atom in dissipative environment
Lingjie Du, Yang Yu
We study microwave-driven cooling in a superconducting flux qubit subjected to environment noises. For the weak decoherence, our analytical results agree well with the experimental…
Low-frequency Landau-Zener-Stückelberg interference in dissipative superconducting qubits
lingjie du, yang yu
Landau-Zener-Stückelberg (LZS) interference of continuously driven superconducting qubits is studied. Going beyond the second order perturbation expansion, we find a time dependent…
Landau-Zener-Stückelberg Interference of Microwave Dressed States of a Superconducting Phase Qubit
Guozhu Sun, Xueda Wen, Bo Mao +6
We present the first observation of Landau-Zener-Stückelberg (LZS) interference of the dressed states arising from an artificial atom, a superconducting phase qubit, interacting wi…
Landau-Zener-Stückelberg Spectroscopy of a Superconducting Flux Qubit
Shuang Xu, Guozhu Sun, Yang Yu
We proposed a new method to measure the energy spectrum of a superconducting flux qubit. Different from the conventional frequency spectroscopy, a short triangle pulse is used to d…
Quantum Dynamics of a Microwave Driven Superconducting Phase Qubit Coupled to a Two-Level System
Guozhu Sun, Xueda Wen, Bo Mao +4
We present an analytical and comprehensive description of the quantum dynamics of a microwave resonantly driven superconducting phase qubit coupled to a microscopic two-level syste…
Tunable Quantum Beam Splitters for Coherent Manipulation of a Solid-State Tripartite Qubit System
Guozhu Sun, Xueda Wen, Bo Mao +4
Coherent control of quantum states is at the heart of implementing solid-state quantum processors and testing quantum mechanics at the macroscopic level. Despite significant progre…
