Implementing quantum walks with a single qubit
Qi-Ping Su, Shi-Chao Wang, Yan Chi +5
Quantum walks have wide applications in quantum information, such as universal quantum computation, so it is important to explore properties of quantum walks thoroughly. We propose…
Coordinately Assisted Distillation of Quantum Coherence in Multipartite System
Huang-Qiu-Chen Wang, Qi Luo, Qi-Ping Su +4
We investigate the issue of assisted coherence distillation in the asymptotic limit (considering infinite copies of the resource states), by coordinately performing the identical l…
High-dimensional multi-input quantum random access codes and mutually unbiased bases
Rui-Heng Miao, Zhao-Di Liu, Yong-Nan Sun +3
Quantum random access codes (QRACs) provide a basic tool for demonstrating the advantages of quantum resources and protocols, which have a wide range of applications in quantum inf…
Experimental and theoretical characterization of a non-equilibrium steady state of a periodically driven qubit
Yong-Nan Sun, Kimmo Luoma, Zhao-Di Liu +3
Periodically driven dynamics of open quantum systems is very interesting because typically non-equilibrium steady state is reached, which is characterized by a non-vanishing curren…
Experimental realization of high-fidelity teleportation via non-Markovian open quantum system
Zhao-Di Liu, Yong-Nan Sun, Bi-Heng Liu +5
Open quantum systems and study of decoherence are important for our fundamental understanding of quantum physical phenomena. For practical purposes, there exists a large number of…
Transverse Confinement of Photon Position in Light-Atom Interaction
Jun Sun, Yong-Nan Sun
In light-pulsed atom interferometry, the phase accumulated by atoms depends on the effective wave vector of the absorbed photons. In this work, we proposed a theory model to analys…
Achieving Heisenberg-scaling precision with projective measurement on single photons
Geng Chen, Lijian Zhang, Wen-Hao Zhang +11
It has been suggested that both quantum superpositions and nonlinear interactions are important resources for quantum metrology. However, to date the different roles that these two…
Realization of a causal-modeled delayed-choice experiment using single photons
Shang Yu, Yong-Nan Sun, Wei Liu +6
Wave-particle duality constitutes one of the most intriguing features in quantum physics. A well-known gedanken experiment that provides evidence for this is the Wheeler's delayed-…
Experimental implementation of fully controlled dephasing dynamics and synthetic spectral densities
Zhao-Di Liu, Henri Lyyra, Yong-Nan Sun +5
Engineering, controlling, and simulating quantum dynamics is a strenuous task. However, these techniques are crucial to develop quantum technologies, preserve quantum properties, a…
Heisenberg-scaling measurement of the single-photon Kerr non-linearity using mixed states
Geng Chen, Nati Aharon, Yong-Nan Sun +7
Improving the precision of measurements is a significant scientific challenge. The challenge is twofold: first, overcoming noise that limits the precision given a fixed amount of a…
Stable Switching among High-Order Modes in Polariton Condensates
Yongbao Sun, Yoseob Yoon, Saeed Khan +6
We report multistate optical switching among high-order bouncing-ball modes ("ripples") and whispering-gallerying modes ("petals") of exciton-polariton condensates in a laser-gener…
Non-Markovian discrete qubit dynamics
Jun Sun, Yong-Nan Sun, Chuan-Feng Li +3
The study of open quantum systems is important for fundamental issues of quantum physics as well as for technological applications such as quantum information processing. The inter…
Bose-Einstein Condensation of Long-Lifetime Polaritons in Thermal Equilibrium
Yongbao Sun, Patrick Wen, Yoseob Yoon +6
Exciton-polaritons in semiconductor microcavities have been used to demonstrate quantum effects such as Bose-Einstein condensation, superfluity, and quantized vortices. However, in…
Storage of multiple single-photon pulses emitted from a quantum dot in a solid-state quantum memory
Jian-Shun Tang, Zong-Quan Zhou, Yi-Tao Wang +15
Quantum repeaters are critical components for distributing entanglement over long distances in presence of unavoidable optical losses during transmission. Stimulated by Duan-Lukin-…
Violation of Leggett-Garg inequalities in single quantum dot
Yong-Nan Sun, Yang Zou, Rong-Chun Ge +3
We investigate the violation of Leggett-Garg (LG) inequalities inquantum dots with the stationarity assumption. By comparing two types of LG inequalities, we find a better one whic…
