Quantum Error-Corrected Computation of Molecular Energies
Kentaro Yamamoto, Yuta Kikuchi, David Amaro +18
We present the first demonstration of an end-to-end pipeline with quantum error correction (QEC) for a quantum computation of the electronic structure of molecular systems. We calc…

Quantum state preparation for multivariate functions
Matthias Rosenkranz, Eric Brunner, Gabriel Marin-Sanchez +5
A fundamental step of any quantum algorithm is the preparation of qubit registers in a suitable initial state. Often qubit registers represent a discretization of continuous variab…

Hamiltonian dynamics simulation using linear combination of unitaries on an ion trap quantum computer
Michelle Wynne Sze, Yao Tang, Silas Dilkes +3
The linear combination of unitaries (LCU) method has proven to scale better than existing product formulas in simulating long time Hamiltonian dynamics. However, given the number o…
