An electron wave packet tunneling through a barrier has a transmission (or “group delay”)
time τ g that, for a rectangular barrier, is commonly held to become independent of the …

It is well known that quantum simulation can be efficiently performed on a quantum computer
rather than a classical one 1. The quantum machine considers all possible cases within …

A numerical solution to the time evolution equation of the Wigner distribution function (WDF)
with an accuracy necessary to simulate the passage of a wave packet past a barrier is …

Electron emission into a nanogap is not instantaneous, which presents a difficulty in
simulating ultra-fast behavior using particle models. A method of approximating the …

Quantum computers are the promising candidates for simulation of large quantum systems,
which is a daunting task to perform in a classical computer. Here, we report the experimental …

The Schrödinger equation is a fundamental equation in quantum mechanics that describes
how wave functions evolve over time. The study explored specific focus on the Crank …

Quantum tunneling, as a quintessential quantum phenomenon, has been investigated in
detail both theoretically and experimentally. Still, the physical picture of the tunneling …

We examine the tunnelling process of incident Hermite-Gaussian wavepackets which
feature several nodes and peaks. An analytic formula for the transmitted wave function is …

We investigate potential scattering and tunneling dynamics of a particle wavepacket
evolving according to the relativistic Schrödinger equation (also known as the Salpeter …

This work proposes a series of quantum experiments that can, at least in principle, allow for
examining microscopic mechanisms associated with decoherence. These experiments can …
