Energy requirement for implementing unitary gates on energy-unbounded systems
Yuxiang Yang, Renato Renner, Giulio Chiribella
The processing of quantum information always has a cost in terms of physical resources such as energy or time. Determining the resource requirements is not only an indispensable st…
Hong-Ou-Mandel Interference between Two Hyper-Entangled Photons Enables Observation of Symmetric and Anti-Symmetric Particle Exchange Phases
Zhi-Feng Liu, Chao Chen, Jia-Min Xu +10
Two-photon Hong-Ou-Mandel (HOM) interference is a fundamental quantum effect with no classical counterpart. The exiting researches on two-photon interference were mainly limited in…
Compression for Qubit Clocks
Yuxiang Yang, Giulio Chiribella, Masahito Hayashi
Two-Ievel (qubit) clock systems are often used to perform precise measurement of time. In this work, we propose a compression protocol for identically prepared states of qubit…
Efficient algorithms for quantum information bottleneck
Masahito Hayashi, Yuxiang Yang
The ability to extract relevant information is critical to learning. An ingenious approach as such is the information bottleneck, an optimisation problem whose solution corresponds…
Experimental Demonstration of Quantum Pseudotelepathy
Jia-Min Xu, Yi-Zheng Zhen, Yu-Xiang Yang +5
Quantum pseudotelepathy is a strong form of nonlocality. Different from the conventional non-local games where quantum strategies win statistically, e.g., the Clauser-Horne-Shimony…
Efficient Deterministic Preparation of Quantum States Using Decision Diagrams
Fereshte Mozafari, Giovanni De Micheli, Yuxiang Yang
Loading classical data into quantum registers is one of the most important primitives of quantum computing. While the complexity of preparing a generic quantum state is exponential…
Nonlinear manipulation of orbital angular momentum spectra with second- and third- harmonic generation in a quasi-periodically poled crystal
Yu-Xiang Yang, Bo-Wen Dong, Zhi-Cheng Ren +7
Optical orbital angular momentum (OAM), as an important degree of freedom of light, has been attracted extensive attention, due to its intrinsic feature of natural discrete infinit…
Third-harmonic generation of spatially structured light in a quasi-periodically poled crystal
Yan-Chao Lou, Zi-Mo Cheng, Yu-Xiang Yang +4
Nonlinear optical processes of spatially structured light, including optical vortex and vector optical fields, have stimulated a lot of interesting physical effects and found a var…
Optimal Strategies of Quantum Metrology with a Strict Hierarchy
Qiushi Liu, Zihao Hu, Haidong Yuan +1
One of the main quests in quantum metrology is to attain the ultimate precision limit with given resources, where the resources are not only of the number of queries, but more impo…
