Selective filtering of multi-photon events from a single-photon emitter

Abstract Single-photon purity is one of the most important key metrics of many quantum states of light. For applications in photonic quantum technologies, e.g. quantum communication and linear optical quantum computing, a minimization of the multi-photon error rate is required be...

Efficient Auxiliary-FieldQuantum Monte Carlo UsingIsometric Tensor Hypercontraction

Abstract Auxiliary Field Quantum Monte Carlo (AFQMC) has emerged as a powerful framework for treating strongly correlated electronic systems, offering a favorable balance between computational cost and accuracy. In this paper, we present a novel AFQMC method that uses the isometr...
