Driven-dissipative four-mode squeezing of multilevel atoms in an optical cavity
Bhuvanesh Sundar, Diego Barbarena, Ana Maria Rey +1
We utilize multilevel atoms trapped in a driven resonant optical cavity to produce scalable multi-mode squeezed states for quantum sensing and metrology. While superradiance or col…
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…
Extending relax-and-round combinatorial optimization solvers with quantum correlations
Maxime Dupont, Bhuvanesh Sundar
We introduce a relax-and-round approach embedding the quantum approximate optimization algorithm (QAOA) with layers. We show for many problems, including Sherrington-Kirk…
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…
Squeezing multilevel atoms in dark states via cavity superradiance
Bhuvanesh Sundar, Diego Barberena, Ana Maria Rey +1
We describe a method to create and store scalable and long-lived entangled spin-squeezed states within a manifold of many-body cavity dark states using collective emission of light…
