Entangletronics

Entanglement has many applications in quantum information theory, quantum computing, superdense coding and quantum teleportation as well as cryptography. Entanglement is used to  advance the measurement accuracy at quantum scales, for surpassing the standard quantum limit towards achieving the Heisenberg limit.

IN QUANTUM HUNTING THE SCHROEDINGER CAT ENTANGLES ITS STATE WITH THE STATE OF THE MOUSE.

We introduce the phrase Entangletronics (short for Entangled Electronics) for an emerging branch of nanoelectronics, which unifies methods and principles for electron state control and engineering, aiming to create quantum states with certain desired properties. Entanglement characterizes the state evolution in electron lenses, mesoscopic (Aharonov-Bohm) rings and Quantum Point Contacts (QPC’s). Electron transport in such structures comprises phenomena with yet not explored physical and application aspects. The underlying physics involves processes of superposition and interference, featuring nanoscale dimensions, which compete with decoherence effects caused by the environment.
