Quantum teleportation using active feed-forward between two Canary Islands

, 2012
Quantum teleportation [1] is a quintessential prerequisite of many quantum information processing protocols [2-4]. By using quantum teleportation, one can circumvent the no-cloning theorem [5] and faithfully transfer unknown quantum states to a party ...

A QUANTUM TELEPORTATION GAME [PDF]

International Journal of Quantum Information, 2005
We investigate a game where a sender (Alice) teleports coherent states to two receivers (Bob and Charlie) through a tripartite Gaussian state. The aim of the receivers is to optimize their teleportation fidelities by means of local operations and classical communications.

Quantum Teleportation with Continuous Variables: a survey

, 2006
Very recently we have witnessed a new development of quantum information, the so-called continuous variable (CV) quantum information theory. Such a further development has been mainly due to the experimental and theoretical advantages offered by CV ...

Constraint on teleportation over multipartite pure states

, 2010
We first define a quantity exhibiting the usefulness of bipartite quantum states for teleportation, called the quantum teleportation capability, and then investigate its restricted shareability in multi-party quantum systems. In this work, we verify that

Teleportation Systems Toward a Quantum Internet

PRX Quantum, 2020
Quantum teleportation is essential for many quantum information technologies, including long-distance quantum networks. Using fiber-coupled devices, including state-of-the-art low-noise superconducting nanowire single-photon detectors and off-the-shelf ...

Two‐Photon Interference from an InAs Quantum Dot Emitting in the Telecom C‐Band

Advanced Quantum Technologies, EarlyView.
A telecom C‐band emitting quantum dot integrated with a circular Bragg grating cavity demonstrates two‐photon interference visibility of 71.9%, which is currently state‐of‐art. The improved two‐photon interference visibility is enabled by optimized growth and Purcell enhancement.

Scheme for Total Quantum Teleportation [PDF]

Physical Review Letters, 2000
We address the issue of totally teleporting the quantum state of an external particle, as opposed to studies on partial teleportation of external single-particle states, total teleportation of coherent states and encoded single-particle states, and intramolecular teleportation of nuclear spin states.

Quantum Circuit Design using a Progressive Widening Enhanced Monte Carlo Tree Search

Advanced Quantum Technologies, EarlyView.
This article proposes the Progressive Widening enhanced Monte Carlo Tree Search (PWMCTS) to design parameterized quantum circuits. It improves the efficiency of the previous MCTS‐based techniques in terms of number of quantum circuit evaluation, number of gates and CNOT count.

Quantum Teleportation of Optical Quantum Gates [PDF]

Physical Review Letters, 2003
We show that a universal set of gates for quantum computation with optics can be quantum teleported through the use of EPR entangled states, homodyne detection, and linear optics and squeezing operations conditioned on measurement outcomes. This scheme may be used for fault-tolerant quantum computation in any optical scheme (qubit or continuous ...
