Extracting random numbers from quantum tunnelling through a single diode. [PDF]
Sci Rep, 2017 Random number generation is crucial in many aspects of everyday life, as online security and privacy depend ultimately on the quality of random numbers.

On the status of quantum tunnelling time
European Journal for Philosophy of Science, 2022 How long does a quantum particle take to traverse a classically forbidden energy barrier? In other words, what is the correct expression for quantum tunnelling time? This seemingly simple question has inspired widespread debate in the physics literature.

Witnessing quantum correlations in two coupled quantum dots under intrinsic decoherence
Alexandria Engineering Journal, 2023 The influences of intrinsic decoherence, tunnelling rates, and Coulomb coupling interaction on the behaviour of negativity, quantum coherence and the measurement-induced disturbance of two coupled quantum dot molecules are discussed.

npj Quantum Information, 2021 Combining external control with long spin lifetime and coherence is a key challenge for solid state spin qubits. Tunnel coupling with electron Fermi reservoir provides robust charge state control in semiconductor quantum dots, but results in undesired ...

On the effect of decoherence on quantum tunnelling
SN Applied Sciences, 2021 This work proposes a series of quantum experiments that can, at least in principle, allow for examining microscopic mechanisms associated with decoherence.

Scientific Reports, 2022 Direct interspecies electron transfer (DIET) has been identified as an efficient metabolism between symbiotically interacting organisms. One method of DIET uses conductive materials (e.g., granular activated carbon (GAC)) as a medium to shuttle electrons

Macroscopic quantum tunnelling in spin filter ferromagnetic Josephson junctions. [PDF]
Nat Commun, 2015 The interfacial coupling of two materials with different ordered phases, such as a superconductor (S) and a ferromagnet (F), is driving new fundamental physics and innovative applications.

Dissipation and Tunnelling in Quantum Hall Bilayers [PDF]
, 2004 We discuss the interplay between transport and intrinsic dissipation in quantum Hall bilayers, within the framework of a simple thought experiment. We compute, for the first time, quantum corrections to the semiclassical dynamics of this system.

Influence of classical resonances on chaotic tunnelling [PDF]
, 2006 Dynamical tunnelling between symmetry-related stable modes is studied in the periodically driven pendulum. We present strong evidence that the tunnelling process is governed by nonlinear resonances that manifest within the regular phase-space islands on ...

Quantum tunnelling, real-time dynamics and Picard-Lefschetz thimbles [PDF]
Journal of High Energy Physics, 2019 We follow up the work, where in light of the Picard-Lefschetz thimble approach, we split up the real-time path integral into two parts: the initial density matrix part which can be represented via an ensemble of initial conditions, and the dynamic part ...
