Fluid fermionic fragments for optimizing quantum measurements of electronic Hamiltonians in the variational quantum eigensolver
Seonghoon Choi, Ignacio Loaiza, Artur F. Izmaylov
Measuring the expectation value of the molecular electronic Hamiltonian is one of the challenging parts of the variational quantum eigensolver. A widely used strategy is to express…

Improving quantum measurements by introducing "ghost" Pauli products
Seonghoon Choi, Tzu-Ching Yen, Artur F. Izmaylov
Reducing the number of measurements required to estimate the expectation value of an observable is crucial for the variational quantum eigensolver to become competitive with state-…
