Design and execution of quantum circuits using tens of superconducting qubits and thousands of gates for dense Ising optimization problems
We develop a hardware-efficient ansatz for variational optimization, derived from existing
ansatzes in the literature, that parametrizes subsets of all interactions in the cost Hamiltonian
in each layer. We treat gate orderings as a variational parameter and observe that doing so
can provide significant performance boosts in experiments. We carried out experimental
demonstration runs of a compilation-optimized implementation of fully connected
Sherrington-Kirkpatrick Hamiltonians on a 50-qubit linear-chain subsystem of Rigetti's …
