Twenty Years of Quantum State Teleportation at the Sapienza University in Rome

Abstract

Quantum teleportation is one of the most striking consequence of quantum mechanics and is defined as the transmission and reconstruction of an unknown quantum state over arbitrary distances. This concept was introduced for the first time in 1993 by Charles Bennett and coworkers, it has then been experimentally demonstrated by several groups under different conditions of distance, amount of particles and even with feed forward. After 20 years from its first realization, this contribution reviews the experimental implementations realized at the Quantum Optics Group of the University of Rome La Sapienza.

Quantum Communication—Celebrating the Silver Jubilee of Teleportation

“…Francesco De Martini and Fabio Sciarrino, in their paper “Twenty years of quantum state teleportation at the Sapienza University in Rome” [ 25 ], review various experiments of quantum teleportation that were conducted at the Sapienza University in Rome, ranging from the first teleportation experiment (1997) to several variations and generalizations of teleportation, such as active teleportation and quantum machines based on teleportation.…”

Research on information lossless teleportation via the W states

“…Quantum communication is a method of transmitting information that uses the unique properties of quantum physics to ensure its security. Quantum entanglement [1] is one of the most common quantum mechanical phenomena in quantum communication which plays a key role in different quantum information processing tasks, such as quantum teleportation (QT) [2], quantum secret sharing [3], quantum cryptography [4] and so on. Entanglement pairs are the basic resources for QT.…”

A Verifiable Arbitrated Quantum Signature Scheme Based on Controlled Quantum Teleportation

“…Quantum cryptography can provide the advantage of unconditional security, making the research of quantum cryptography increasingly important. Many important quantum cryptography branches have been developed, such as quantum key distribution [ 2 , 3 ], quantum signature (QS) [ 4 , 5 , 6 ], quantum teleportation (QT) [ 7 ], quantum authentication [ 8 ], and deterministic secure quantum communication [ 9 ].…”
