Quantum computing for quantum tunneling [PDF]
Physical Review D, 2021 We demonstrate how quantum field theory problems can be embedded on quantum annealers. The general method we use is a discretisation of the field theory problem into a general Ising model, with the continuous field values being encoded into Ising spin chains.

Quantum battles in attoscience: tunnelling [PDF]
The European Physical Journal D, 2021 Abstract What is the nature of tunnelling? This yet unanswered question is as pertinent today as it was at the dawn of quantum mechanics. This article presents a cross section of current perspectives on the interpretation, computational modelling, and numerical investigation of tunnelling processes in attosecond physics

Quantum Tunneling on Graphs [PDF]
Communications in Mathematical Physics, 2012 We explore the tunneling behavior of a quantum particle on a finite graph, in the presence of an asymptotically large potential. Surprisingly the behavior is governed by the local symmetry of the graph around the wells.

Aromaticity switching by quantum tunnelling. [PDF]
Chem SciCarbon tunnelling in pentalene-based polycyclic molecules enables ultrafast π-bond rearrangements switching local aromaticity/antiaromaticity, or leading to a quantum “Schrödinger's aromaticity cat” in a coherent tunnelling regime.

Tunneling Quantum Dynamics in Ammonia [PDF]
International Journal of Molecular Sciences, 2021 Ammonia is a well-known example of a two-state system and must be described in quantum-mechanical terms. In this article, we will explain the tunneling phenomenon that occurs in ammonia molecules from the perspective of trajectory-based quantum dynamics, rather than the usual quantum probability perspective.

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

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.
