Digital-Analog Simulations of Schrödinger Cat States in the Dicke-Ising Model
Dmitriy S. Shapiro, Yannik Weber, Tim Bode +2
The Dicke-Ising model, one of the few paradigmatic models of matter-light interaction, exhibits a superradiant quantum phase transition above a critical coupling strength. However,…
Limitations of Quantum Approximate Optimization in Solving Generic Higher-Order Constraint-Satisfaction Problems
Thorge Müller, Ajainderpal Singh, Frank K. Wilhelm +1
The ability of the Quantum Approximate Optimization Algorithm (QAOA) to deliver a quantum advantage on combinatorial optimization problems is still unclear. Recently, a scaling adv…
Quantum combinatorial optimization beyond the variational paradigm: simple schedules for hard problems
Tim Bode, Krish Ramesh, Tobias Stollenwerk
Advances in quantum algorithms suggest a tentative scaling advantage on certain combinatorial optimization problems. Recent work, however, has also reinforced the idea that barren…
Adiabatic Bottlenecks in Quantum Annealing and Nonequilibrium Dynamics of Paramagnons
Tim Bode, Frank K. Wilhelm
The correspondence between long-range interacting quantum spin glasses and combinatorial optimization problems underpins the physical motivation for adiabatic quantum computing. On…
Noise-Robust Detection of Quantum Phase Transitions
Kevin Lively, Tim Bode, Jochen Szangolies +2
Quantum computing allows for the manipulation of highly correlated states whose properties quickly go beyond the capacity of any classical method to calculate. Thus one natural pro…
