Quantum Spacetime on a Quantum Simulator
Keren Li, Youning Li, Muxin Han +8
We experimentally simulate the spin networks -- a fundamental description of quantum spacetime at the Planck level. We achieve this by simulating quantum tetrahedra and their inter…
Holevo Bound of Entropic Uncertainty in Schwarzschild Spacetime
Jin-Long Huang, Wen-Cong Gan, Yunlong Xiao +2
For a pair of incompatible quantum measurements, the total uncertainty can be bounded by a state-independent constant. However, such a bound can be violated if the quantum system i…
Quantum Simulation of the Non-Fermi-Liquid State of Sachdev-Ye-Kitaev Model
Zhihuang Luo, Yi-Zhuang You, Jun Li +5
The Sachdev-Ye-Kitaev (SYK) model incorporates rich physics, ranging from exotic non-Fermi liquid states without quasiparticle excitations, to holographic duality and quantum chaos…
Experimental Machine Learning of Quantum States
Jun Gao, Lu-Feng Qiao, Zhi-Qiang Jiao +7
Quantum information technologies provide promising applications in communication and computation, while machine learning has become a powerful technique for extracting meaningful s…
NMRCloudQ: A Quantum Cloud Experience on a Nuclear Magnetic Resonance Quantum Computer
Tao Xin, Shilin Huang, Sirui Lu +7
As of today, no one can tell when a universal quantum computer with thousands of logical quantum bits (qubits) will be built. At present, most quantum computer prototypes involve l…
Implementing universal nonadiabatic holonomic quantum gates with transmons
Zhuo-Ping Hong, Bao-Jie Liu, Jia-Qi Cai +4
Geometric phases are well known to be noise-resilient in quantum evolutions/operations. Holonomic quantum gates provide us with a robust way towards universal quantum computation,…
Neural-network-designed pulse sequences for robust control of singlet-triplet qubits
Xu-Chen Yang, Man-Hong Yung, Xin Wang
Composite pulses are essential for universal manipulation of singlet-triplet spin qubits. In the absence of noise, they are required to perform arbitrary single-qubit operations du…
A Separability-Entanglement Classifier via Machine Learning
Sirui Lu, Shilin Huang, Keren Li +7
The problem of determining whether a given quantum state is entangled lies at the heart of quantum information processing, which is known to be an NP-hard problem in general. Despi…
Incompatibility of Observables as State-Independent Bound of Uncertainty Relations
Yunlong Xiao, Cheng Guo, Fei Meng +2
For a pair of observables, they are called "incompatible", if and only if the commutator between them does not vanish, which represents one of the key features in quantum mechanics…
Optimal experiment design for quantum state tomography
Jun Li, Shilin Huang, Zhihuang Luo +3
Quantum state tomography is an indispensable but costly part of many quantum experiments. Typically, it requires measurements to be carried in a number of different settings on a f…
Transforming Bell's Inequalities into State Classifiers with Machine Learning
Yue-Chi Ma, Man-Hong Yung
Quantum information science has profoundly changed the ways we understand, store, and process information. A major challenge in this field is to look for an efficient means for cla…
Measuring Holographic Entanglement Entropy on a Quantum Simulator
Keren Li, Muxin Han, Dongxue Qu +6
Quantum simulation promises to have wide applications in many fields where problems are hard to model with classical computers. Various quantum devices of different platforms have…
Interaction-free measurement study as a quantum channel discrimination problem
You Zhou, Man-Hong Yung
Interaction-free measurement (IFM), just as its name implies, can enable one to detect an object without interacting with it, i.e., substantially reducing the damage to the object.…
Simulating Molecular Spectroscopy with Circuit Quantum Electrodynamics
Ling Hu, YueChi Ma, Y. Xu +5
Spectroscopy is a crucial laboratory technique for understanding quantum systems through their interactions with electromagnetic radiation. Particularly, spectroscopy is capable of…
Heat and work along individual trajectories of a quantum bit
M. Naghiloo, D. Tan, P. M. Harrington +4
We use a near quantum limited detector to experimentally track individual quantum state trajectories of a driven qubit formed by the hybridization of a waveguide cavity and a trans…
