X-ResQ: Reverse Annealing for Quantum MIMO Detection with Flexible Parallelism
Minsung Kim, Abhishek Kumar Singh, Davide Venturelli +2
Quantum Annealing (QA)-accelerated MIMO detection is an emerging research approach in the context of NextG wireless networks. The opportunity is to enable large MIMO systems and th…
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…
Uplink MIMO Detection using Ising Machines: A Multi-Stage Ising Approach
Abhishek Kumar Singh, Ari Kapelyan, Davide Venturelli +1
Multiple-Input-Multiple-Output~(MIMO) signal detection is central to every state-of-the-art communication system, and enhancements in error performance and computation complexity o…
Memory-induced oscillations of a driven particle in a dissipative correlated medium
Davide Venturelli, Andrea Gambassi
The overdamped dynamics of a particle is in general affected by its interaction with the surrounding medium, especially out of equilibrium, and when the latter develops spatial and…
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…
Tracer particle in a confined correlated medium: an adiabatic elimination method
Davide Venturelli, Markus Gross
We present a simple and systematic procedure to determine the effective dynamics of a Brownian particle coupled to a rapidly fluctuating correlated medium, modeled as a scalar Gaus…
