Quantum Sensing and Hamiltonian Learning under Stochastic Parameter Evolution
Kelvin Koor, Patrick Rebentrost
We introduce the notion of stochastically evolving Hamiltonians (SEHs), which are local Hamiltonians whose coefficients are governed by stochastic differential equations (SDEs). Af…
Quantum Quasi-Monte Carlo: a window for pre-asymptotic quantum advantage
Paolo Recchia, Zhan Yu, Kelvin Koor +1
Numerical integration with Monte Carlo methods is a central computational task in many scientific and industrial applications, including financial derivative pricing and risk manag…
