Hamiltonian Switching Control of Noisy Bipartite Qubit Systems
Hamiltonian Switching Control of Noisy Bipartite Qubit Systems
Abstract We develop a Hamiltonian switching ansatz for bipartite control that is inspired by the quantum approximate optimization algorithm, to mitigate environmental noise on qubits. We demonstrate the control for a central spin coupled to bath spins via isotropic Heisenberg interactions, and then make physical applications to the protection of …
