Periodic Plane-Wave Electronic Structure Calculations on Quantum Computers

2022 · Research Square

Abstract A procedure for defining virtual spaces, and the periodic one-electron and two-electron integrals, for plane-wave second quantized Hamiltonians has been developed and demonstrated using full configuration interaction (FCI) simulations and variational quantum eigensolver (VQE) …

Factoring using 2n+2 qubits with Toffoli based modular multiplication

2016 · arXiv (Cornell University)

We describe an implementation of Shor's quantum algorithm to factor n-bit integers using only 2n+2 qubits. In contrast to previous space-optimized implementations, ours features a purely Toffoli based modular multiplication circuit. The circuit depth and …

A Reference Implementation for a Quantum Message Passing Interface

2023

Practical applications of quantum computing are currently limited by the number of qubits that can be set with reasonable fidelity for each system. Therefore, a distributed quantum computing system with multiple quantum computers coherently connected …
