Quantum Simulation of Tunneling in Small Systems
A number of quantum algorithms have been performed on small quantum computers; these include Shor's prime factorization algorithm, error correction, Grover's search algorithm and a number of analog and digital quantum simulations. Because of the number of gates and qubits necessary, however, digital quantum particle simulations remain untested. A contributing factor to the system size required ...
متن کاملExperimental simulation of quantum tunneling in small systems
It is well known that quantum computers are superior to classical computers in efficiently simulating quantum systems. Here we report the first experimental simulation of quantum tunneling through potential barriers, a widespread phenomenon of a unique quantum nature, via NMR techniques. Our experiment is based on a digital particle simulation algorithm and requires very few spin-1/2 nuclei wit...
متن کاملTunneling in open quantum systems
Processes involving quantum tunneling can be found in a huge variety of physical and chemical systems, ranging in length from the mesoscopic scale of a few microns to the subatomic scale of a few fermi. It has been realized already three decades ago that thereby the interaction of the tunneling degree of freedom with environmental degrees of freedom plays a crucial role. Namely, any realistic d...
متن کاملQuantum Tunneling in Half-Integer Spin Systems
Motivated by the experimental observations of resonant tunnelings in the systems with half-integer spin, such as V15 and Mn4, we study the mechanism of adiabatic change of the magnetization in systems with the time-reversal symmetry. Within the time-reversal symmetric models, effects of several types of perturbations are investigated. Although tunneling between the ground states is suppressed i...
متن کاملTunneling with Dissipation in Open Quantum Systems
Based on the general form of the master equation for open quantum systems the tunneling is considered. Using the path integral technique a simple closed form expression for the tunneling rate through a parabolic barrier is obtained. The tunneling in the open quantum systems strongly depends on the coupling with environment. We found the cases when the dissipation prohibits tunneling through the...
