Two-Dimension Asymmetric Electromagnetically Induced Grating in Rydberg Atoms
Photonics, 2022 We investigate the realization and manipulation of a two-dimension (2D), asymmetric, electromagnetically induced grating (EIG) in a sample of Rydberg atoms exhibiting the van der Waals (vdW) interactions.

Quantum singular value transformation and beyond: exponential improvements for quantum matrix arithmetics [PDF]
, 2018 Quantum computing is powerful because unitary operators describing the time-evolution of a quantum system have exponential size in terms of the number of qubits present in the system.

Quantum Simulation of Antiferromagnetic Heisenberg Chain with Gate-Defined Quantum Dots [PDF]
Physical Review X, 2021 Quantum-mechanical correlations of interacting fermions result in the emergence of exotic phases. Magnetic phases naturally arise in the Mott-insulator regime of the Fermi-Hubbard model, where charges are localized and the spin degree of freedom remains.

AIP Advances, 2011 In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator would not. An ideal quantum simulator would be controllable, and built using existing technology.

Digital Quantum Simulation of the Schwinger Model and Symmetry Protection with Trapped Ions [PDF]
PRX Quantum, 2021 Tracking the dynamics of physical systems in real time is a prime application of digital quantum computers. Using a trapped-ion system with up to six qubits, we simulate the real-time dynamics of a lattice gauge theory in 1+1 dimensions, i.e., the ...

Quantum Simulations with Circuit Quantum Electrodynamics [PDF]
, 2017 Superconducting circuits have become a leading quantum technology for testing fundamentals of quantum mechanics and for the implementation of advanced quantum information protocols. In this chapter, we revise the basic concepts of circuit network theory and circuit quantum electrodynamics for the sake of digital and analog quantum simulations of ...

Subspace variational quantum simulator
Physical Review Research, 2023 Quantum simulation is one of the key applications of quantum computing, which accelerates research and development in the fields such as chemistry and material science. The recent development of noisy intermediate-scale quantum (NISQ) devices urges the exploration of applications without the necessity of quantum error correction.

Holographic Quantum Simulation of Entanglement Renormalization Circuits [PDF]
PRX Quantum, 2022 While standard approaches to quantum simulation require a number of qubits proportional to the number of simulated particles, current noisy quantum computers are limited to tens of qubits.
