Realization of an n-qubit controlled-U gate with superconducting quantum interference devices or atoms in cavity QED
Chui-Ping Yang, Siyuan Han
We propose an approach to realize an -qubit controlled- gate with superconducting quantum interference devices (SQUIDs) in cavity QED. In this approach, the two lowest levels…
A scheme for the teleportation of multiqubit quantum information via the control of many agents in a network
Chui-Ping Yang, Siyuan Han
We present a new scheme for teleporting multiqubit quantum information from a sender to a distant receiver via the control of many agents in a network. We show that the receiver ca…
A unified approach to realize universal quantum gates in a coupled two-qubit system with fixed always-on coupling
Zhongyuan Zhou, Shih-I Chu, Siyuan Han
We demonstrate that in a coupled two-qubit system any single-qubit gate can be decomposed into two conditional two-qubit gates and that any conditional two-qubit gate can be implem…
Rapid optimization of working parameters of microwave-driven multi-level qubits for minimal gate leakage
Zhongyuan Zhou, Shih-I Chu, Siyuan Han
We propose an effective method to optimize the working parameters (WPs) of microwave-driven quantum logical gates implemented with multi-level physical qubits. We show that by trea…
Measurement of Dissipation of a Three-Level rf SQUID Qubit
Shao-Xiong Li, Wei Qiu, Zhongyuan Zhou +4
The dissipation-induced relaxation (T_1) time of a macroscopic quantum system - a \{lambda}-type three-level rf SQUID flux qubit weakly coupled to control and readout circuitry (CR…
Extracting an arbitrary relative phase from a multiqubit two-component entangled state
Chui-Ping Yang, Siyuan Han
We show that an arbitrary relative phase can be extracted from a multiqubit two-component (MTC) entangled state by local Hadamard transformations and measurements along a single ba…
