Adiabatic approximation in the ultrastrong-coupling regime of a system consisting of an oscillator and two qubits
Ping Yang, Zhi-Ming Zhang
We present a system composed of two flux qubits and a transmission-line resonator. Instead of using the rotating wave approximation (RWA), we analyse the system by the adiabatical…
Implementation of local and high-fidelity quantum conditional phase gates in a scalable two-dimensional ion trap
Ping Zou, Jian Xu, Wei song +1
We propose a scheme to implement high-fidelity conditional phase gates on pair of trapped ions immersed in a two-dimensional Coulomb crystal, using interaction mediated by all axia…
Experimental implementation of high-fidelity unconventional geometric quantum gates using NMR interferometer
J. Du, P. Zou, Z. D. Wang
Following a key idea of unconventional geometric quantum computation developed earlier [Phys. Rev. Lett. 91, 197902 (2003)], here we propose a more general scheme in such an intrig…
Experimental Demonstration of Quantum State Multi-meter and One-qubit Fingerprinting in a Single Quantum Device
Jiangfeng Du, Ping Zou, Daniel K. L. Oi +4
We experimentally demonstrate in NMR a quantum interferometric multi-meter for extracting certain properties of unknown quantum states without resource to quantum tomography. It ca…
Experimental Quantum Cloning with Prior Partial Information
Jiangfeng Du, Thomas Durt, Ping Zou +5
When prior partial information about a state to be cloned is available, it can be cloned with a fidelity higher than that of universal quantum cloning. We experimentally verify thi…
Experimental demonstration of an efficient quantum phase-covariant cloning and its possible applications to simulating eavesdropping in quantum cryptography
Jiangfeng Du, Thomas Durt, Ping Zou +4
We describe a nuclear magnetic resonance (NMR) experiment which implements an efficient one-to-two qubit phase-covariant cloning machine(QPCCM). In the experiment we have achieved…
