Quantum Energy Teleportation with Trapped Ions
We analyse a protocol of quantum energy teleportation that transports energy from the left edge of a linear ion crystal to the right edge by local operations and classical communication at a speed considerably greater than the speed of a phonon in the crystal. A probe qubit is strongly coupled with phonon fluctuation in the ground state for a short time, and it is projectively measured in order...
متن کاملQuantum Energy Teleportation: An Introductory Review
The development of techniques for manipulation of quantum information has opened the door to a variety of protocols for accomplishing unprecedented tasks. In particular, a new protocol of quantum teleportation was proposed in 2008 to achieve e¤ective energy transportation simply via local operations and classical communication without breaking any known physical laws. This is achieved by extr...
متن کاملQuantum Energy Teleportation in Spin Chain Systems
We propose a protocol of quantum energy teleportation that transports energy in spin chains to distant sites by only local operations and classical communication. The protocol uses ground-state entanglement and localized negative-energy excitation, and the energy is teleported without breaking any physical laws including causality and local energy conservation.
متن کاملQuantum kinetic energy densities: an operational approach.
We propose and investigate a procedure to measure, at least in principle, a positive quantum version of the local kinetic energy density. This procedure is based, under certain idealized limits, on the detection rate of photons emitted by moving atoms which are excited by a localized laser beam. The same type of experiment, but in different limits, can also provide other non-positive-definite v...
متن کاملGround-State Entanglement Gives Birth to Quantum Energy Teleportation
Ground-state entanglement induces emergence of negativeenergy-density regions in quantum systems by squeezing zero-point oscillation, keeping total energy of the systems nonnegative. By use of the negativity of quantum energy density, protocols of quantum energy teleportation are proposed that transport energy to distant sites by local operations and classical communication. The energy is telep...
