Distributed Quantum Computing and Network Control for Accelerated VQE

Understand

Interconnecting small quantum computers will be essential in the future for creating large scale, robust quantum computers.

• Methods for distributing monolithic quantum algorithms efficiently are thus needed.
• In this work we consider an approach for distributing the accelerated variational quantum eigensolver (AVQE) algorithm over arbitrary sized - in terms of number of qubits - distributed quantum computers.
• We consider approaches for distributing qubit assignments of the Ansatz states required to estimate the expectation value of Hamiltonian operators in quantum chemistry in a parallelized computation and provide a systematic approach to generate distributed quantum circuits for distributed quantum computing.
