Implementation of the Projective Quantum Eigensolver on a Quantum Computer
Jonathon P. Misiewicz, Francesco A. Evangelista
We study the performance of our previously proposed Projective Quantum Eigensolver (PQE) on IBM's quantum hardware in conjunction with error mitigation techniques. For a single qub…
CNOT-Efficient Circuits for Arbitrary Rank Many-Body Fermionic and Qubit Excitations
Ilias Magoulas, Francesco A. Evangelista
Efficient quantum circuits are necessary for realizing quantum algorithms on noisy intermediate-scale quantum devices. Fermionic excitations entering unitary coupled-cluster (UCC)…
Leveraging small scale quantum computers with unitarily downfolded Hamiltonians
Renke Huang, Chenyang Li, Francesco A. Evangelista
In this work, we propose a quantum unitary downfolding formalism based on the driven similarity renormalization group (QDSRG) that may be combined with quantum algorithms for both…
AGP-based unitary coupled cluster theory for quantum computers
Armin Khamoshi, Guo P. Chen, Francesco A. Evangelista +1
Electronic structure methods typically benefit from symmetry breaking and restoration, specially in the strong correlation regime. The same goes for Ansätze on a quantum computer.…
QForte: an efficient state simulator and quantum algorithms library for molecular electronic structure
Nicholas H. Stair, Francesco A. Evangelista
We introduce a novel open-source software package QForte, a comprehensive development tool for new quantum simulation algorithms. QForte incorporates functionality for handling mol…
Simulating Many-Body Systems with a Projective Quantum Eigensolver
Nicholas H. Stair, Francesco A. Evangelista
We present a new hybrid quantum-classical algorithm for optimizing unitary coupled-cluster (UCC) wave functions deemed the projective quantum eigensolver (PQE), amenable to near-te…
Correlating AGP on a quantum computer
Armin Khamoshi, Francesco A. Evangelista, Gustavo E. Scuseria
For variational algorithms on the near term quantum computing hardware, it is highly desirable to use very accurate ansatze with low implementation cost. Recent studies have shown…
