Quantum annealing inspired algorithms for the NISQ Era
Rijul Sachdeva, Vrinda Mehta, Manpreet Singh Jattana +2
We study algorithms inspired by quantum annealing that are suited for the NISQ era. First, we analyze approximate quantum annealing (AQA), which employs a discretized annealing ans…
Universal Quantum Computer Simulation of 50 Qubits on Europe`s First Exascale Supercomputer Harnessing Its Heterogeneous CPU-GPU Architecture
Hans De Raedt, Jiri Kraus, Andreas Herten +5
We have developed a new version of the high-performance Jülich universal quantum computer simulator (JUQCS-50) that leverages key features of the GH200 superchips as used in the JU…
Understanding the physics of D-Wave annealers: From Schrödinger to Lindblad to Markovian Dynamics
Vrinda Mehta, Hans De Raedt, Kristel Michielsen +1
Understanding the physical nature of the D-Wave annealers remains a subject of active investigation. In this study, we analyze the sampling behavior of these systems and explore wh…
Unraveling Reverse Annealing: A Study of D-Wave Quantum Annealers
Vrinda Mehta, Hans De Raedt, Kristel Michielsen +1
D-Wave quantum annealers offer reverse annealing as a feature allowing them to refine solutions to optimization problems. This paper investigates the influence of key parameters, s…
Performance of quantum annealing for 2-SAT problems with multiple satisfying assignments
Vrinda Mehta, Hans De Raedt, Kristel Michielsen +1
Using a specially constructed set of hard 2-SAT problems with four satisfying assignments, we study the scaling and sampling performance of numerical simulation of quantum annealin…
Can foreign exchange rates violate Bell inequalities?
Hans De Raedt, Mikhail I. Katsnelson, Manpreet S. Jattana +5
The analysis of empirical data through model-free inequalities leads to the conclusion that violations of Bell-type inequalities by empirical data cannot have any significance unle…
Einstein-Podolsky-Rosen-Bohm experiments: a discrete data driven approach
Hans De Raedt, Mikhail I. Katsnelson, Manpreet S. Jattana +5
We take the point of view that building a one-way bridge from experimental data to mathematical models instead of the other way around avoids running into controversies resulting f…
Model-free inequality for data of Einstein-Podolsky-Rosen-Bohm experiments
Hans De Raedt, Mikhail I. Katsnelson, Manpreet S. Jattana +5
We present a new inequality constraining correlations obtained when performing Einstein-Podolsky-Rosen-Bohm experiments. The proof does not rely on mathematical models that are ima…
On the hardness of quadratic unconstrained binary optimization problems
Vrinda Mehta, Fengping Jin, Kristel Michielsen +1
We use exact enumeration to characterize the solutions of quadratic unconstrained binary optimization problems of less than 21 variables in terms of their distributions of Hamming…
Quantum annealing for hard 2-SAT problems : Distribution and scaling of minimum energy gap and success probability
Vrinda Mehta, Fengping Jin, Hans De Raedt +1
In recent years, quantum annealing has gained the status of being a promising candidate for solving various optimization problems. Using a set of hard 2-satisfiabilty (2-SAT) probl…
Quantum Annealing with Trigger Hamiltonians: Application to 2-SAT and Nonstoquastic Problems
Vrinda Mehta, Fengping Jin, Hans De Raedt +1
We study the performance of quantum annealing for two sets of problems, namely, 2-satisfiability (2-SAT) problems represented by Ising-type Hamiltonians, and nonstoquastic problems…
