On the fragility of gate-error metrics in simulation models of flux-tunable transmon quantum computers
Hannes Lagemann, Dennis Willsch, Madita Willsch +3
Constructing a quantum computer requires immensely precise control over a quantum system. A lack of precision is often quantified by gate-error metrics, such as the average infidel…
Classical, quantum and event-by-event simulation of a Stern-Gerlach experiment with neutrons
Hans De Raedt, Fengping Jin, Kristel Michielsen
We present a comprehensive simulation study of the Newtonian and quantum model of a Stern-Gerlach experiment with cold neutrons.By solving Newton's equation of motion and the time-…
Spatiotemporal dynamics of classical and quantum density profiles in low-dimensional spin systems
Tjark Heitmann, Jonas Richter, Fengping Jin +3
We provide a detailed comparison between the dynamics of high-temperature spatiotemporal correlation functions in quantum and classical spin models. In the quantum case, our large-…
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…
Sustaining Rabi oscillations by using a phase-tunable image drive
H. De Raedt, S. Miyashita, K. Michielsen +3
Recent electron spin resonance experiments on CaWO:Gd and on other magnetic impurities have demonstrated that sustained Rabi oscillations can be created by driving a mag…
Improved variational quantum eigensolver via quasi-dynamical evolution
Manpreet Singh Jattana, Fengping Jin, Hans De Raedt +1
The variational quantum eigensolver (VQE) is a hybrid quantum-classical algorithm designed for current and near-term quantum devices. Despite its initial success, there is a lack o…
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…
Assessment of the variational quantum eigensolver: application to the Heisenberg model
Manpreet Singh Jattana, Fengping Jin, Hans De Raedt +1
We present and analyze large-scale simulation results of a hybrid quantum-classical variational method to calculate the ground state energy of the anti-ferromagnetic Heisenberg mod…
Numerical analysis of effective models for flux-tunable transmon systems
Hannes Lagemann, Dennis Willsch, Madita Willsch +3
Simulations and analytical calculations that aim to describe flux-tunable transmons are usually based on effective models of the corresponding lumped-element model. However, when a…
