High fidelity and flexible quantum state transfer in the atom-coupled cavity hybrid system
(SpringerNew YorkEUA, 2013)
A method to improve quantum state fidelity in circuits executed on ibm’s quantum computers
(2021-01-01)
Recently, various quantum computing and communication tasks have been implemented using IBM’s superconductivity-based quantum computers. Here, we show that the circuits used in most of those works were not optimized and ...
Multifractality In Fidelity Sequences Of Optimized Toffoli Gates
(SpringerNew York, 2016)
Alternative fidelity measure between quantum states
(2008-11-19)
We propose an alternative fidelity measure (namely, a measure of the degree of similarity) between quantum states and benchmark it against a number of properties of the standard Uhlmann-Jozsa fidelity. This measure is a ...
Remote state preparation of a photonic quantum state via quantum teleportation
(Springer Verlag Berlín, 2014-06)
We demonstrate an experimental realization of remote state preparation via the quantum teleportation algorithm, using an entangled photon pair in the polarization degree of freedom as the quantum resource. The input state ...
Sensitivity to perturbations and quantum phase transition
(Amer Physical Soc, 2013-05-17)
The local density of states or its Fourier transform, usually called fidelity amplitude, are important measures of quantum irreversibility due to imperfect evolution. In this Rapid Communication we study both quantities ...
Controlled high-fidelity navigation in the charge stability diagram of a double quantum dot
(Iop Publishing, 2015-03)
We propose an efficient control protocol for charge transfer in a double quantum dot. We consider numerically a two-dimensional model system, where the quantum dots are subjected to time-dependent electric fields ...
Exact dynamics of single-qubit-gate fidelities under the measurement-based quantum computation scheme
(Amer Physical Soc, 2012-10-19)
Measurement-based quantum computation is an efficient model to perform universal computation. Nevertheless, theoretical questions have been raised, mainly with respect to realistic noise conditions. In order to shed some ...

Quantum and classical complexity in coupled maps
(American Physical Society, 2017-12)
We study a generic and paradigmatic two-degrees-of-freedom system consisting of two coupled perturbed cat maps with different types of dynamics. The Wigner separability entropy (WSE)—equivalent to the operator space ...
