Unveiling the origins of quasi-phase matching spectral imperfections in thin-film lithium niobate frequency doublers

open access: yesAPL Photonics, 2023
Thin-film lithium niobate (TFLN) based frequency doublers have widely been recognized as an essential component for both classical and quantum optical communications.

An elegant scheme of self-testing for multipartite Bell inequalities

open access: yesnpj Quantum Information, 2023
Self-testing is the most accurate form of certification of quantum devices. While self-testing in bipartite Bell scenarios has been thoroughly studied, self-testing in the more complex multipartite Bell scenarios remains largely unexplored.

Quantum States Transfer by Analogous Bell States [PDF]

open access: yesCommunications in Theoretical Physics, 2008
Transmitting quantum states by channels of analogous Bell states is studied in this paper. We analyse the transmitting process, constructed the probabilitic unitary operator, and gain the largest successful transfer quantum state probability.

Verifiable Threshold Quantum State Sharing Scheme

open access: yesIEEE Access, 2018
Quantum state sharing (QSTS) is a hot topic in quantum cryptography. However, majority of the current structures cannot resist the participant's fraud well during the initial state reconstruction phase.

Bell States, Bell Operators, and Total Teleportation

open access: yesZeitschrift für Naturforschung A, 2001
Abstract We identify the operators and the corresponding physical quantities whose measurement allows in principle to obtain total teleportation of the unknown spin state of a single electron. We introduce an analogous scheme for a single photon and discuss its experimental implementation.

Robustness of Bell violation of graph states to qubit loss

open access: yesPhysical Review Research, 2023
Graph states are special entangled states advantageous for many quantum technologies, including quantum error correction, multiparty quantum communication, and measurement-based quantum computation.

Bayesian estimation for Bell state rotations

open access: yesAVS Quantum Science, 2023
This paper explores the effect of three-dimensional rotations on two-qubit Bell states and proposes a Bayesian method for the estimation of the parameters of the rotation. We use a particle filter to estimate the parameters of the rotation from a sequence of Bell state measurements, and we demonstrate that the resultant improvement over the optimal ...

Waveform Design for 5G Networks: Analysis and Comparison

open access: yesIEEE Access, 2017
The next-generation cellular network is to provide a large variety of services for different kinds of terminals, from traditional voice and data services over mobile phones to small packet transmission over massive machine-type terminals.

Dissipative preparation of generalized Bell states [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2013
A scheme is presented for the dissipative preparation of generalised Bell states of two-qubits, within the context of cavity QED. In the suggested protocol the dissipative processes of spontaneous emission and cavity loss are no longer undesirable, but essential to the required dynamics.
