Accelerating Quantum Computations of Chemistry Through Regularized Compressed Double Factorization

Oumarou Oumarou, Maximilian Scheurer, Robert M. Parrish +2

We propose the regularized compressed double factorization (RC-DF) method to classically compute compressed representations of molecular Hamiltonians that enable efficient simulati…

Purification-based quantum error mitigation of pair-correlated electron simulations

T. E. O'Brien, G. Anselmetti, F. Gkritsis +173

An important measure of the development of quantum computing platforms has been the simulation of increasingly complex physical systems. Prior to fault-tolerant quantum computing,…

Efficient Quantum Analytic Nuclear Gradients with Double Factorization

Edward G. Hohenstein, Oumarou Oumarou, Rachael Al-Saadon +4

Efficient representations of the Hamiltonian such as double factorization drastically reduce circuit depth or number of repetitions in error corrected and noisy intermediate scale…

Optimizing the information extracted by a single qubit measurement

Stefano Polla, Gian-Luca R. Anselmetti, Thomas E. O'Brien

We consider a quantum computation that only extracts one bit of information per -qubit quantum state preparation. This is relevant for error mitigation schemes where the remaind…
