Taking a Closer Look at Quantum Teleportation

9 October 2017, 5.00 PM - 9 October 2017, 6.00 PM

Dr Paul Skrzypczyk (Physics, Bristol)

Frank Lecture Theatre H H Wills Physics Laboratory, Tyndall Avenue, Bristol BS8 1TL

 

 Quantum teleportation, the process by which a quantum state is transferred from one place to another, using quantum entanglement and classical communication, is one of the cornerstones of quantum information. In experimental, non-ideal implementations, when the entanglement is noisy, quantum teleportation can be approximately realised, with the quantum state transferred up to some noise. Conventional wisdom says that some forms of noisy entanglement are useless for performing such approximate teleportation. In this talk I will explain how, taking a closer look at the full data produced in a teleportation experiment, this turns out to be untrue. I will show that all types of entanglement are useful for performing quantum teleportation, as well as uncover some new aspects of teleportation.

 
*These colloquia start at 17:00 on Mondays in the Frank lecture.
