Measurements of Quantum Hamiltonians with Locally-Biased Classical Shadows
Charles Hadfield, Sergey Bravyi, Rudy Raymond +1
Obtaining precise estimates of quantum observables is a crucial step of variational quantum algorithms. We consider the problem of estimating expectation values of molecular Hamilt…
