Utilizing encoding time as a resource to enhance quantum sensing by probe qubit dephasing
Ji-Bing Yuan, Hai-Fei Liu, Ya-Ju Song +3
We examine a system in which an impurity qubit is immersed in a quasi-two-dimensional dipolar Bose-Einstein condensate whose collective excitations act as a depasing reservoir for…
Antisymmetry-breaking-coupling-enhanced sensing of quantum reservoirs
Ji-Bing Yuan, Zhi-Min Tang, Ya-Ju Song +4
We investigate the utilization of a single generalized dephasing qubit for sensing a quantum reservoir, where the antisymmetric coupling between the qubit and its reservoir is brok…
Quantum sensing of temperature close to absolute zero in a Bose-Einstein condensate
Ji-Bing Yuan, Bo Zhang, Ya-Ju Song +3
We propose a theoretical scheme for quantum sensing of temperature close to absolute zero in a quasi-one-dimensional Bose-Einstein condensate (BEC). In our scheme, a single-atom im…
Effect of weak measurement on entanglement distribution over noisy channels
Xin-Wen Wang, Sixia Yu, Deng-Yu Zhang +1
Being able to implement effective entanglement distribution in noisy environments is a key step towards practical quantum communication, and long-term efforts have been made on the…
Entanglement-enhanced two-photon delocalization in a coupled-cavity array
Shi-Qing Tang, Ji-Bing Yuan, Xin-Wen Wang +1
We study transport properties of two entangled photons which are initially injected into two nearest-neighbor coupling cavities in a one-dimensional coupled-cavity array (CCA). It…
Manipulation of tripartite-to-bipartite entanglement localization under quantum noises and its application to entanglement distribution
Xin-Wen Wang, Shi-Qing Tang, Ji-Bing Yuan +1
This paper is to investigate the effects of quantum noises on entanglement localization by taking an example of reducing a three-qubit Greenberger-Horne-Zeilinger (GHZ) state to a…
Quantum-discord-induced superradiance and subradiance in a system of two separated atoms
Shi-Qing Tang, Ji-Bing Yuan, Xin-Wen Wang +1
We investigate collective radiant properties of two separated atoms in X-type quantum states. We show that quantum correlations measured by quantum discord (QD) can induce and enha…
Nonmaximally entangled states can be better for quantum correlation distribution and storage
Xin-Wen Wang, Shi-Qing Tang, Ji-Bing Yuan +1
For carrying out many quantum information protocols entanglement must be established in advance between two distant parties. Practically, inevitable interaction of entangled subsys…
Many-to-one remote information concentration for qudits and multipartite entanglement
Xin-Wen Wang, Shi-Qing Tang, Li-Jun Xie +2
Telecloning and its reverse process, referred to as remote information concentration(RIC), have attracted considerable interest because of their potential applications in quantum-i…
Photonic two-qubit parity gate with tiny cross-Kerr nonlinearity
Xin-Wen Wang, Deng-Yu Zhang, Shi-Qing Tang +3
The cross-Kerr nonlinearity (XKNL) effect can induce efficient photon interactions in principle with which photonic multiqubit gates can be performed using far fewer physical resou…
Remote information concentration and multipartite entanglement in multilevel systems
Xin-Wen Wang, Deng-Yu Zhang, Guo-Jian Yang +2
Remote information concentration (RIC) in -level systems (qudits) is studied. It is shown that the quantum information initially distributed in three spatially separated qudits…
Multiparty hierarchical quantum-information splitting
Xin-Wen Wang, Deng-Yu Zhang, Shi-Qing Tang +1
We propose a scheme for multiparty hierarchical quantum-information splitting (QIS) with a multipartite entangled state, where a boss distributes a secret quantum state to two grad…
Genuine (k, m)-threshold controlled teleportation and its security
Xin-Wen Wang, Da-Chuang Li, Guo-Jian Yang
We propose genuine (, )-threshold controlling schemes for controlled teleportation via multi-particle entangled states, where the teleportation of a quantum state from a send…
Hierarchical quantum information splitting
Xin-Wen Wang, Li-Xin Xia, Zhi-Yong Wang
We present a scheme for asymmetric quantum information splitting, where a sender distributes asymmetrically a qubit to distant agents in a network. The asymmetric distribution lead…
