In matters relating to quantum information theory, it is convenient to work with the simplest possible unit of information: the two-state system of the qubit.The qubit functions as the quantum analog of the classic computational part, the bit, as it can have a measurement value of both a 0 and a 1, whereas the classical bit can only be measured as a 0 or a 1.

The choice of whether to measure a qubit before, after, or during an operation conditioned on that qubit will have no observable effect on a circuit's final expected results. Thanks to the deferred measurement principle, measurements in a quantum circuit can often be shifted around so they happen at better times. For example, measuring qubits ...
Additionally, gate teleportation is a key component of magic state distillation, a technique that can be used to overcome the limitations of the Eastin-Knill theorem. [ 3 ] Quantum gate teleportation has been demonstrated in various types of quantum computers, including linear optical, [ 4 ] superconducting quantum computing , [ 5 ] and trapped ...
Entanglement swapping is a form of quantum teleportation. In quantum teleportation, the unknown state of a particle can be sent from one location to another using the combination of a quantum and classical channel. The unknown state is projected by Alice onto a Bell state and the result is communicated to Bob through the classical channel. [4]
In quantum teleportation, a sender wishes to transmit an arbitrary quantum state of a particle to a possibly distant receiver. Consequently, the teleportation process is a quantum channel. The apparatus for the process itself requires a quantum channel for the transmission of one particle of an entangled-state to the receiver.
Quantum teleportation promises a leap into the next great era of computing -- but first we've got to get it working consistently. Scientists at the Kavli Institute of Nanoscience Delft say they've ...
String diagrams for rigid categories can be defined as non-progressive plane graphs, i.e. the edges can bend backward. In the context of categorical quantum mechanics, this is known as the snake equation. The category of Hilbert spaces is rigid, this fact underlies the proof of correctness for the quantum teleportation protocol.
