Coherent Control of Quantum Entropy via Quantum Interference in a Four-Level Atomic System
The time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. Quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. It is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. The phase dependence of the atom-field entanglement is...

متن کاملQuantum Erasure: Quantum Interference Revisited
It may be somewhat surprising that Thomas Young’s double-slit experiment a staple in the freshman physics laboratory would be such an invaluable testing ground for the foundations of quantum physics. Yet the quantum version of the double-slit experiment has been at the center of many debates over the fundamentals of quantum physics since the theory was born, nearly a century ago. In fact, Young...
متن کاملGraphene quantum interference photodetector
In this work, a graphene quantum interference (QI) photodetector was simulated in two regimes of operation. The structure consists of a graphene nanoribbon, Mach-Zehnder interferometer (MZI), which exhibits a strongly resonant transmission of electrons of specific energies. In the first regime of operation (that of a linear photodetector), low intensity light couples two resonant energy levels,...
متن کاملQuantum interference in polyenes.
The explicit form of the zeroth Green's function in the Hückel model, approximated by the negative of the inverse of the Hückel matrix, has direct quantum interference consequences for molecular conductance. We derive a set of rules for transmission between two electrodes attached to a polyene, when the molecule is extended by an even number of carbons at either end (transmission unchanged) or ...
