Efficient computation of real-time correlators using Pauli Propagation
Alexander F. Kemper, Raghav G. Jha, Arnab Bachhar +3
Pauli propagation has shown promise for classically simulating quantum dynamics by evolving observables directly in the Heisenberg picture. In this work, we investigate its use for…
TIMES-ADAPT: A Quantum algorithm for real-time evolution in low-energy subspaces using fixed-depth circuits
Bharath Sambasivam, Kyle Sherbert, Karunya Shirali +3
We propose a new variational quantum algorithm, which we refer to as TIMES-ADAPT, that prepares time-evolved states in a low-energy or symmetric subspace of a time-independent Hami…
Co-Designed Adaptive Quantum State Preparation Protocols
Mafalda Ramôa, Luis Paulo Santos, Nicholas J. Mayhall +2
We propose a co-designed variant of ADAPT-VQE (Co-ADAPT-VQE) where the quantum hardware is taken into account in the construction of the ansatz. This framework can be readily used…
