Model-free readout-error mitigation for quantum expectation values
Ewout van den Berg, Zlatko K. Minev, Kristan Temme
Measurements on current quantum processors are subject to hardware imperfections that lead to readout errors. These errors manifest themselves as a bias in quantum expectation valu…
A simple method for sampling random Clifford operators
Ewout van den Berg
We describe a simple algorithm for sampling -qubit Clifford operators uniformly at random. The algorithm outputs the Clifford operators in the form of quantum circuits with at m…
Efficient Bayesian phase estimation using mixed priors
Ewout van den Berg
We describe an efficient implementation of Bayesian quantum phase estimation in the presence of noise and multiple eigenstates. The main contribution of this work is the dynamic sw…
Circuit optimization of Hamiltonian simulation by simultaneous diagonalization of Pauli clusters
Ewout van den Berg, Kristan Temme
Many applications of practical interest rely on time evolution of Hamiltonians that are given by a sum of Pauli operators. Quantum circuits for exact time evolution of single Pauli…
