Quantum simulation and computing with Rydberg-interacting qubits [PDF]
AVS Quantum Science, 2020 Arrays of optically trapped atoms excited to Rydberg states have recently emerged as a competitive physical platform for quantum simulation and computing, where high-fidelity state preparation and readout, quantum logic gates and controlled quantum ...

Quantum Simulators and Quantum Repeaters [PDF]
Fortschritte der Physik, 2000 It is shown that a photon from a non-maximal singlet, obtained by a controlled entanglement of two downconverted photon pairs, can be entangled with a photon from another such singlet. As a result the other photons from the singlets appear in a singlet state with an event probability arbitrary close to one.

Complete Characterization of a Quantum Process: the Two-Bit Quantum Gate [PDF]
, 1996 We show how to fully characterize a quantum process in an open quantum system. We particularize the procedure to the case of a universal two-qubit gate in a quantum computer.

Generalized quantum assisted simulator
Quantum Science and Technology, 2022 Abstract We provide a noisy intermediate-scale quantum framework for simulating the dynamics of open quantum systems, generalized time evolution, non-linear differential equations and Gibbs state preparation. Our algorithm does not require any classical–quantum feedback loop, bypass the barren plateau problem and does not necessitate ...

Simulated quantum annealing as a simulator of nonequilibrium quantum dynamics [PDF]
Physical Review A, 2021 Simulated quantum annealing based on the path-integral Monte Carlo is one of the most common tools to simulate quantum annealing on classical hardware. Nevertheless, it is in principle highly non-trivial whether or not this classical algorithm can correctly reproduce the quantum dynamics of quantum annealing, particularly in the diabatic regime.

Radical pairs may play a role in xenon-induced general anesthesia
Scientific Reports, 2021 Understanding the mechanisms underlying general anesthesia would be a key step towards understanding consciousness. The process of xenon-induced general anesthesia has been shown to involve electron transfer, and the potency of xenon as a general ...

Classical wave-optics analogy of quantum information processing [PDF]
, 2001 An analogous model system for quantum information processing is discussed, based on classical wave optics. The model system is applied to three examples that involve three qubits: ({\em i}) three-particle Greenberger-Horne-Zeilinger entanglement, ({\em ...

Quantum simulation of nonequilibrium dynamics and thermalization in the Schwinger model [PDF]
Physical Review D, 2021 We present simulations of non-equilibrium dynamics of quantum field theories on digital quantum computers. As a representative example, we consider the Schwinger model, a 1+1 dimensional U(1) gauge theory, coupled through a Yukawa-type interaction to a ...

Tools for quantum simulation with ultracold atoms in optical lattices [PDF]
Nature Reviews Physics, 2020 After many years of development of the basic tools, quantum simulation with ultracold atoms has now reached the level of maturity at which it can be used to investigate complex quantum processes.
