Design and execution of quantum circuits using tens of superconducting qubits and thousands of gates for dense Ising optimization problems
Filip B. Maciejewski, Stuart Hadfield, Benjamin Hall +13
We develop a hardware-efficient ansatz for variational optimization, derived from existing ansatze in the literature, that parametrizes subsets of all interactions in the Cost Hami…
Quantum-Enhanced Greedy Combinatorial Optimization Solver
Maxime Dupont, Bram Evert, Mark J. Hodson +13
Combinatorial optimization is a broadly attractive area for potential quantum advantage, but no quantum algorithm has yet made the leap. Noise in quantum hardware remains a challen…
Towards solving the Fermi-Hubbard model via tailored quantum annealers
Ryan Levy, Zoe Gonzalez Izquierdo, Zhihui Wang +8
The Fermi-Hubbard model (FHM) on a two dimensional square lattice has long been an important testbed and target for simulating fermionic Hamiltonians on quantum hardware. We presen…
Advantage of pausing: parameter setting for quantum annealers
Zoe Gonzalez Izquierdo, Shon Grabbe, Husni Idris +3
Prior work showed the efficacy of pausing midanneal: such a pause improved the probability of success by orders of magnitude in a class of native problem instances and improved the…
Logical shadow tomography: Efficient estimation of error-mitigated observables
Hong-Ye Hu, Ryan LaRose, Yi-Zhuang You +2
We introduce a technique to estimate error-mitigated expectation values on noisy quantum computers. Our technique performs shadow tomography on a logical state to produce a memory-…
Dual Map Framework for Noise Characterization of Quantum Computers
James Sud, Jeffrey Marshall, Zhihui Wang +2
In order to understand the capabilities and limitations of quantum computers, it is necessary to develop methods that efficiently characterize and benchmark error channels present…
