Reducing the Resources Required by ADAPT-VQE Using Coupled Exchange Operators and Improved Subroutines
Mafalda Ramôa, Panagiotis G. Anastasiou, Luis Paulo Santos +3
Adaptive variational quantum algorithms arguably offer the best prospects for quantum advantage in the Noisy Intermediate-Scale Quantum era. Since the inception of the first such a…
Minimal evolution times for fast, pulse-based state preparation in silicon spin qubits
Christopher K. Long, Nicholas J. Mayhall, Sophia E. Economou +5
Standing as one of the most significant barriers to reaching quantum advantage, state-preparation fidelities on noisy intermediate-scale quantum processors suffer from quantum-gate…
Restricted Open-shell cluster Mean-Field theory for Strongly Correlated Systems
Arnab Bachhar, Nicholas J. Mayhall
The cluster-based Mean Field method (cMF) and it's second order perturbative correction[1], was introduced by Jiménez-Hoyos and Scuseria to reduce the cost of modeling strongly cor…
Parameterization and optimizability of pulse-level VQEs
Kyle M Sherbert, Hisham Amer, Sophia E Economou +2
In conventional variational quantum eigensolvers (VQEs), trial states are prepared by applying series of parameterized gates to a reference state, with the gate parameters being va…
Accurate and Interpretable Representation of Correlated Electronic Structure via Tensor Product Selected CI
Nicole M. Braunscheidel, Arnab Bachhar, Nicholas J. Mayhall
The task of computing wavefunctions that are accurate, yet simple enough mathematical objects to use for reasoning has long been a challenge in quantum chemistry. The difficulty in…
Physically motivated improvements of Variational Quantum Eigensolvers
Nonia Vaquero-Sabater, Abel Carreras, Román Orús +2
The Adaptive Derivative-Assembled Pseudo-Trotter Variational Quantum Eigensolver (ADAPT-VQE) has emerged as a pivotal promising approach for electronic structure challenges in quan…
Reducing measurement costs by recycling the Hessian in adaptive variational quantum algorithms
Mafalda Ramôa, Luis Paulo Santos, Nicholas J. Mayhall +2
