Beyond-Ten-Hour Coherence in a Decoherence-Free Trapped-Ion Clock Qubit
Jiahao Pi, Xiangjia Liu, Junle Cao +8
Quantum systems promise to revolutionize information processing science and technology [1-3]. The preservation of quantum coherence, the defining property of qubits, fundamentally…
On-demand Photonic Ising Machine with Simplified Hamiltonian Calculation by Phase encoding and Intensity Detection
Jiayi Ouyang, Yuxuan Liao, Zhiyao Ma +8
The photonic Ising machine is a new paradigm of optical computing that takes advantage of the unique properties of light wave propagation, parallel processing, and low-loss transmi…
Modular Quantum Computation in a Trapped Ion System
Kuan Zhang, Jayne Thompson, Xiang Zhang +7
Modern computation relies crucially on modular architectures, breaking a complex algorithm into self-contained subroutines. A client can then call upon a remote server to implement…
Operational effects of the UNOT gate on classical and quantum correlations
Kuan Zhang, Jiajun Ma, Xiang Zhang +4
The NOT gate that flips a classical bit is ubiquitous in classical information processing. However its quantum analogue, the universal NOT (UNOT) gate that flips a quantum spin in…
Verification of the Quantum Nonequilibrium Work Relation in the Presence of Decoherence
Andrew Smith, Yao Lu, Shuoming An +6
Although nonequilibrium work and fluctuation relations have been studied in detail within classical statistical physics, extending these results to open quantum systems has proven…
Fermion-antifermion scattering via boson exchange in a trapped ion
Xiang Zhang, Kuan Zhang, Yangchao Shen +7
Quantum field theories describe a wide variety of fundamental phenomena in physics. However, their study often involves cumbersome numerical simulations. Quantum simulators, on the…
Experimental Test of Hyper-Complex Quantum Theories
Lorenzo M. Procopio, Lee A. Rozema, Zi Jing Wong +5
In standard quantum mechanics, complex numbers are used to describe the wavefunction. Although complex numbers have proven sufficient to predict the results of existing experiments…
Quantum Implementation of Unitary Coupled Cluster for Simulating Molecular Electronic Structure
Yangchao Shen, Xiang Zhang, Shuaining Zhang +3
In classical computational chemistry, the coupled-cluster ansatz is one of the most commonly used methods, which is critically limited by its non-unitary nature. The un…
Time Reversal and Charge Conjugation in an Embedding Quantum Simulator
Xiang Zhang, Yangchao Shen, Junhua Zhang +6
The understanding of symmetry operations has brought enormous advancements in physics, ranging from elementary particle to condensed matter systems. In quantum mechanics, symmetry…
Realization of Geometric Landau-Zener-Stückelberg Interferometry
Junhua Zhang, Jingning Zhang, Xiang Zhang +1
We report the first experimental realization of the geometric Landau-Zener-Stückelberg (LZS) interferometry proposed by [Phys. Rev. Lett. 107, 207002 (2011)] in a single trapped io…
State-independent experimental tests of quantum contextuality in a three dimensional system
Xiang Zhang, Mark Um, Junhua Zhang +6
We experimentally observed state-independent violations of Kochen-Specker inequalities for the simplest indivisible quantum system manifesting quantum contextuality, a three-level…
