Detecting Violations of Differential Privacy for Quantum Algorithms
Ji Guan, Wang Fang, Mingyu Huang +1
Quantum algorithms for solving a wide range of practical problems have been proposed in the last ten years, such as data search and analysis, product recommendation, and credit sco…
Detection of entangled states supported by reinforcement learning
Jia-Hao Cao, Feng Chen, Qi Liu +4
Discrimination of entangled states is an important element of quantum enhanced metrology. This typically requires low-noise detection technology. Such a challenge can be circumvent…
Performing SU() operations and rudimentary algorithms in a superconducting transmon qudit for and
Pei Liu, Ruixia Wang, Jing-Ning Zhang +11
Quantum computation architecture based on -level systems, or qudits, has attracted considerable attention recently due to their enlarged Hilbert space. Extensive theoretical and…
Single-Photon-Memory Measurement-Device-Independent Quantum Secure Direct Communication -- Part I: Its Fundamentals and Evolution
Xiang-Jie Li, Dong Pan, Gui-Lu Long +1
Quantum secure direct communication (QSDC) has attracted a lot of attention, which exploits deep-rooted quantum physical principles to guarantee unconditional security of communica…
Probing Complex-energy Topology via Non-Hermitian Absorption Spectroscopy in a Trapped Ion Simulator
Mingming Cao, Kai Li, Wending Zhao +6
Non-Hermitian systems generically have complex energies, which may host topological structures, such as links or knots. While there has been great progress in experimentally engine…
Mechanical Squeezing via Detuning-Switched Driving
Yaohua Li, An-Ning Xu, Long-Gang Huang +1
Generation of mechanical squeezing has attracted a lot of interest for its nonclassical properties, applications in quantum information, and high-sensitivity measurement. Here we p…
