Quantum teleportation, a means of transferring the identity of one particle to another over some distance, made its debut in Physical Review Letters in 1993.
Quantum teleportation, because of the word t eleportation , may seem to bring us to the edge of science fiction. But not so fast. Quantum teleportation refers to the use of a quantum entanglement apparatus with its entangled photon pair source, its two detection stages, plus additional necessary optics, to transport a quantum state from one site to another site. This is done via the use of quantum entanglement probability amplitudes and with the help of a classical transmission of a unitary transformation . A unitary transformation is a mathematical matrix that takes the form of https://www.w3.org/1998/Math/MathML" display="inline"> I , σ x , σ z , or i σ y , where I is the identity matrix and the Greek characters refer to the Pauli matrices.
