Quantum Simulation of Strongly Correlated Fermion-Phonon Models in Circuit QED
Tim Bode, Riccardo Roma, Stefan Schmitz +4
Gate-based digital quantum simulations offer an exciting new paradigm for studying the many-body physics of strongly correlated systems. In this context, electron-phonon models are…
Beyond-mean-field fluctuations for the solution of constraint satisfaction problems
Niklas Foos, Bastian Epping, Jannik Grundler +5
Constraint Satisfaction Problems (CSPs) lie at the heart of complexity theory and find application in a plethora of prominent tasks ranging from cryptography to genetics. Classical…
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…
