Assessing System Capabilities and Bottlenecks of an Early Fault-Tolerant Bicycle Architecture
Kun Liu, Ben Foxman, Gian-Luca R. Anselmetti +1
Early modular fault tolerant quantum computers remain constrained by costly inter-module communication and limited magic state factory service. Understanding such bottlenecks and i…
Improving the runtime of quantum phase estimation for chemistry through basis set optimization
Pauline J. Ollitrault, Jerome F. Gonthier, Dario Rocca +5
Quantum phase estimation (QPE) is a promising quantum algorithm for obtaining molecular ground-state energies with chemical accuracy. However, its computational cost, dominated by…
Dividing and Conquering the Van Vleck Catastrophe
Sophia Simon, Gian-Luca R. Anselmetti, Raffaele Santagati +4
The quantum-computational cost of determining ground state energies through quantum phase estimation depends on the overlap between an easily preparable initial state and the targe…
Classical optimisation of reduced density matrix estimations with classical shadows using N-representability conditions under shot noise considerations
Gian-Luca R. Anselmetti, Matthias Degroote, Nikolaj Moll +2
Classical shadow tomography has become a powerful tool in learning about quantum states prepared on a quantum computer. Recent works have used classical shadows to variationally en…
Enhancing initial state overlap through orbital optimization for faster molecular electronic ground-state energy estimation
Pauline J. Ollitrault, Cristian L. Cortes, Jerome F. Gonthier +7
The quantum phase estimation algorithm stands as the primary method for determining the ground state energy of a molecular electronic Hamiltonian on a quantum computer. In this con…
Analytical Ground- and Excited-State Gradients for Molecular Electronic Structure Theory from Hybrid Quantum/Classical Methods
Robert M. Parrish, Gian-Luca R. Anselmetti, Christian Gogolin
We develop analytical gradients of ground- and excited-state energies with respect to system parameters including the nuclear coordinates for the hybrid quantum/classical multistat…
