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…
Spectral theory of the frame flow on hyperbolic 3-manifolds (with an appendix by Charles Hadfield)
Colin Guillarmou, Charles Hadfield, Benjamin Küster
We study the spectral theory and the resolvent of the vector field generating the frame flow of closed hyperbolic 3-dimensional manifolds on some family of anisotropic Sobolev spac…
Ruelle zeta function from field theory
Charles Hadfield, Santosh Kandel, Michele Schiavina
We propose a field-theoretic interpretation of Ruelle zeta function, and show how it can be seen as the partition function for theory when an unusual gauge fixing condition on…
