Teleportation of massive particles without shared entanglement

Abstract

We propose a method for quantum state transfer from one atom laser beam to another via an intermediate optical field, using Raman incoupling and outcoupling techniques. Our proposal utilises existing experimental technologies to teleport macroscopic matter waves over potentially large distances without shared entanglement.

Raman schemes for phase sensitive measurement and teleportation of massive particles

Ashton S. Bradley, M. K. Olsen, Simon A. Haine +1 more

The Raman atom-laser outcoupler, which is based on optical Bose-enhancement, provides a coherent way to generate an atom laser beam from a Bose-Einstein condensate. In this theoretical work we show that a Raman atom laser incoupler, which utilises atomic Bose-enhancement, can be used to make phase sensitive quadrature measurements of an atom laser beam. An incoupler-outcoupler sequence can be used to teleport an input atom laser beam to a spatially separated location via an intermediate optical field.

We explore the feasibility of creating a translationally entangled state for massive particles, and its use for matter wave teleportation by means of cold-molecule Raman dissociation and association in optical traps.

Proposal for teleportation of the wave function of a massive particle

A. S. Parkins, Harry J. Kimble

We propose a scheme for teleporting an atomic center-of-mass wave function between distant locations. The scheme uses interactions in cavity quantum electrodynamics to facilitate a coupling between the motion of an atom trapped inside a cavity and external propagating light fields. This enables the distribution of quantum entanglement and the realization of the required motional Bell-state analysis.

Stationary Source of Nonclassical or Entangled Atoms

Michael Fleischhauer, Shangqing Gong

A scheme for generating continuous beams of atoms in nonclassical or entangled quantum states is proposed and analyzed. For this the recently suggested transfer technique of quantum states from light fields to collective atomic excitation by stimulated Raman adiabatic passage [M. Fleischhauer and M. D. Lukin, Phys. Rev. Lett. 84, 5094 (2000)] is employed and extended to matter waves.

An Investigation on Quantum Teleportation

Shefali Singhal, Anjali Jain, Anil Kumar Gankotiya +1 more

Teleportation also called, as Quantum Teleportation is a technique, which involves the duplication or re-creation of physical properties using light beams. Teleportation involves the transfer of States between two separate atoms. It relies on a strange behaviour that exists at the atomic scale known as entanglement, whereby two particles can have related properties even when they are far apart. Entanglement allows particles to have a much closer relationship than is possible in classical physics. If two particles are entangled, we can know the state of one particle by measuring the state of the other. For example, two particles can be entangled such that the spin of one particle is always up when the spin of the other is down, and vice versa. An additional feature of quantum mechanics is that the particle can exist in a superposition of both these states at the same time. The landmark experiments are being viewed as a major advance in the quest to achieve ultra-fast computers, inside which teleportation could provide a form of invisible wiring. These machines would be able to handle far bigger and more complex loads than today's super-computers, and at many times their speed. Here in this report, we are going to discuss about the technique involved in quantum computing, quantum cryptography and quantum teleportation and in specific Quantum Computers along with its advantages and disadvantages. Moreover, the future aspects of quantum teleportation such as human teleportation have also been overviewed.
