On the experimental verification of the uncertainty principle of position and momentum
Thomas Schürmann, Ingo Hoffmann, Winfrid Görlich
Historically, Kennard was the first to choose the standard deviation as a quantitative measure of uncertainty, and neither he nor Heisenberg explicitly explained why this choice sh…
Unbalanced penalization: A new approach to encode inequality constraints of combinatorial problems for quantum optimization algorithms
Alejandro Montanez-Barrera, Dennis Willsch, Alberto Maldonado-Romo +1
Solving combinatorial optimization problems of the kind that can be codified by quadratic unconstrained binary optimization (QUBO) is a promising application of quantum computation…
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…
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…
Folding lattice proteins with quantum annealing
Anders Irbäck, Lucas Knuthson, Sandipan Mohanty +1
Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure…
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…
