The 5 most significant breakthroughs in quantum computing
Introduction · Breakthrough #1: Quantum supremacy · Breakthrough #2: Quantum error correction · Breakthrough #3: Fault-tolerant quantum computing.
first investigated in 1993
Quantum teleportation was <anchor>first investigated in 1993</anchor> by scientists who were using it as a way to send and receive quantum information. It was experimentally realized only 4 years later, in 1997, by two independent research groups. The basic principle behind quantum teleportation is entanglement (when two particles remain connected even when separated by vast distances).

#### Abstract

An unknown quantum state ‖φ〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations. To do so the sender, ‘‘Alice,’’ and the receiver, ‘‘Bob,’’ must prearrange the sharing of an EPR-correlated pair of particles. Alice makes a joint measurement on her EPR particle and the unknown quantum system, and sends Bob the classical result of this measurement. Knowing this, Bob can convert the state of his EPR particle into an exact replica of the unknown state ‖φ〉 which Alice destroyed.

##### [Letters from the Past - A PRL Retrospective](http://journals.aps.org/prl/50years/milestones)

2008 marked PRL’s 50th anniversary. As part of the celebrations a collection of milestone Letters was started. The collection contains Letters that have made long-lived contributions to physics, either by announcing significant discoveries, or by initiating new areas of research.
