Long-Time Correlations in Single-Neutron Interferometry Data
M. Willsch, D. Willsch, K. Michielsen +5
We present a detailed analysis of the time series of time-stamped neutron counts obtained by single-neutron interferometry. The neutron counting statistics display the usual Poisso…
Experimental protection of quantum coherence by using a phase-tunable image drive
Sylvain Bertaina, Hervé Vezin, Hans De Raedt +1
The protection of qubit coherence is an essential task in order to build a practical quantum computer able to manipulate, store and read quantum information with a high degree of f…
Spin-relaxation times exceeding seconds for color centers with strong spin-orbit coupling in SiC
Carmem M. Gilardoni, Tom Bosma, Danny van Hien +6
Spin-active color centers in solids show good performance for quantum technologies. Several transition-metal defects in SiC offer compatibility with telecom and semiconductor indus…
Benchmarking the Quantum Approximate Optimization Algorithm
Madita Willsch, Dennis Willsch, Fengping Jin +2
The performance of the quantum approximate optimization algorithm is evaluated by using three different measures: the probability of finding the ground state, the energy expectatio…
Real-time simulation of flux qubits used for quantum annealing
Madita Willsch, Dennis Willsch, Fengping Jin +2
The real-time flux dynamics of up to three superconducting quantum interference devices (SQUIDs) are studied by numerically solving the time-dependent Schrödinger equation. The num…
Plasmon-assisted two-photon Rabi oscillations in a semiconductor quantum dot -- metal nanoparticle heterodimer
Bintoro S. Nugroho, Alexander A. Iskandar, Victor A. Malyshev +1
Tho-photon Rabi oscillations hold potential for quantum computing and quantum information processing, because during a Rabi cycle a pair of entangled photons may be created. We the…
Separation of conditions as a prerequisite for quantum theory
Hans De Raedt, Mikhail I. Katsnelson, Dennis Willsch +1
We introduce the notion of "separation of conditions" meaning that a description of statistical data obtained from experiments, performed under a set of different conditions, allow…
Testing quantum fault tolerance on small systems
D. Willsch, M. Willsch, F. Jin +2
We extensively test a recent protocol to demonstrate quantum fault tolerance on three systems: (1) a real-time simulation of five spin qubits coupled to an environment with two-lev…
Massively parallel quantum computer simulator, eleven years later
Hans De Raedt, Fengping Jin, Dennis Willsch +5
A revised version of the massively parallel simulator of a universal quantum computer, described in this journal eleven years ago, is used to benchmark various gate-based quantum a…
Quantum dynamics of a small symmetry breaking measurement device
H. C. Donker, H. De Raedt, M. I. Katsnelson
A quantum measuring instrument is constructed that utilises symmetry breaking to enhance a microscopic signal. The entire quantum system consists of a system-apparatus-environment…
Analysis of Wigner's Set Theoretical Proof for Bell-type inequalities
Karl Hess, Hans De Raedt, Kristel Michielsen
We present a detailed analysis of the set theoretical proof of Wigner for Bell type inequalities with the following result. Wigner introduced a crucial assumption that is not relat…
From Boole to Leggett-Garg: Epistemology of Bell-type Inequalities
Karl Hess, Hans De Raedt, Kristel Michielsen
In 1862, George Boole derived an inequality for variables, now known as Boolean variables, that in his opinion represents a demarcation line between possible and impossible experie…
Counterfactual Definiteness and Bell's Inequality
Karl Hess, Hans De Raedt, Kristel Michielsen
Counterfactual definiteness must be used as at least one of the postulates or axioms that are necessary to derive Bell-type inequalities. It is considered by many to be a postulate…
Logical inference approach to relativistic quantum mechanics: derivation of the Klein-Gordon equation
H. C. Donker, M. I. Katsnelson, H. De Raedt +1
The logical inference approach to quantum theory, proposed earlier [Ann. Phys. 347 (2014) 45-73], is considered in a relativistic setting. It is shown that the Klein-Gordon equatio…
Eigenstate Thermalization Hypothesis and Quantum Jarzynski Relation for Pure Initial States
F. Jin, R. Steinigeweg, H. De Raedt +3
Since the first suggestion of the Jarzynski equality many derivations of this equality have been presented in both, the classical and the quantum context. While the approaches and…
Quantum theory as plausible reasoning applied to data obtained by robust experiments
H. De Raedt, M. I. Katsnelson, K. Michielsen
We review recent work that employs the framework of logical inference to establish a bridge between data gathered through experiments and their objective description in terms of hu…
Quantum Decoherence and Thermalization at Finite Temperature within the Canonical Thermal State Ensemble
M. A. Novotny, F. Jin, S. Yuan +3
We study measures of decoherence and thermalization of a quantum system in the presence of a quantum environment (bath) . The entirety is prepared in a canonical t…
Nonlinear actuation dynamics of driven Casimir oscillators with rough surfaces
Wijnand Broer, Holger Waalkens, Vitaly B. Svetovoy +2
At separations below 100 nm, Casimir-Lifshitz forces strongly influence the actuation dynamics of micro-electromechanical systems (MEMS) in dry vacuum conditions. For a micron size…
Event-based simulation of quantum physics experiments
Kristel Michielsen, Hans De Raedt
We review an event-based simulation approach which reproduces the statistical distributions of wave theory not by requiring the knowledge of the solution of the wave equation of th…
