Operationally classical simulation of quantum states [PDF]
Nature CommunicationsA classical state-preparation device cannot generate states in relative superposition. We introduce classical models in which devices that are individually unable to generate states with relative superposition can be stochastically coordinated to ...

Classical simulation of non-Gaussian fermionic circuits [PDF]
Quantum, 2023 We propose efficient algorithms for classically simulating fermionic linear optics operations applied to non-Gaussian initial states. By gadget constructions, this provides algorithms for fermionic linear optics with non-Gaussian operations.

Semi-classical simulation of spin-1 magnets [PDF]
Physical Review Research, 2022 Theoretical studies of magnets have traditionally concentrated on either classical spins, or the extreme quantum limit of spin-1/2. However, magnets built of spin-1 moments are also intrinsically interesting, not least because they can support quadrupole,

Classical simulation of photonic linear optics with lost particles [PDF]
New Journal of Physics, 2018 We explore the possibility of efficient classical simulation of linear optics experiments under the effect of particle losses. Specifically, we investigate the canonical boson sampling scenario in which an n -particle Fock input state propagates through ...

Certifying the classical simulation cost of a quantum channel [PDF]
Physical Review Research, 2021 A fundamental objective in quantum information science is to determine the cost in classical resources of simulating a particular quantum system. The classical simulation cost is quantified by the signaling dimension which specifies the minimum amount of

Classical simulation of boson sampling with sparse output. [PDF]
Sci Rep, 2020 Boson sampling can simulate physical problems for which classical simulations are inefficient. However, not all problems simulated by boson sampling are classically intractable.

Efficient Classical Simulation of Random Shallow 2D Quantum Circuits [PDF]
Physical Review X, 2022 A central question of quantum computing is determining the source of the advantage of quantum computation over classical computation. Even though simulating quantum dynamics on a classical computer is thought to require exponential overhead in the worst ...

Quantum simulation in the semi-classical regime [PDF]
Quantum, 2022 Solving the time-dependent Schrödinger equation is an important application area for quantum algorithms. We consider Schrödinger's equation in the semi-classical regime. Here the solutions exhibit strong multiple-scale behavior due to a small parameter $\

Classical simulation of linear optics subject to nonuniform losses [PDF]
Quantum, 2020 We present a comprehensive study of the impact of non-uniform, i.e. path-dependent, photonic losses on the computational complexity of linear-optical processes. Our main result states that, if each beam splitter in a network induces some loss probability,
