[quantum-info] Q+ Hangout: Tuesday March 26 10:00 am QNC:B201

[Aharon Brodutch]

Hi all
The next Q+ Hangout will be in the QNC videoconferencing room.

Tuesday March 26 10:00 am  QNC:B201
Speaker:Ivette Fuentes (University of Nottingham)
Title: Quantum information processing in spacetime

Cutting-edge experiments in quantum communications are reaching regimes
where relativistic effects can no longer be neglected. For example, there
are advanced plans to use satellites to implement teleportation and quantum
cryptographic protocols. Relativistic effects can be expected at these
regimes: the Global Positioning System (GPS), which is a system of
satellites that is used for time dissemination and navigation, requires
relativistic corrections to determine time and positions accurately.
Therefore, it is timely to understand what are the effects of gravity and
motion on entanglement and other quantum properties exploited in quantum
information.
In this talk I will show that entanglement can be created or degraded by
gravity and non-uniform motion.  While relativistic effects can degrade the
efficiency of teleportation between moving observers, the effects can also
be exploited in quantum information. I will show that the relativistic
motion of a quantum system can be used to perform quantum gates.  Our
results, which will impact future space-based experiments, can be
demonstrated in table-top experiments using superconducting circuits.
