Distributed Quantum Information Processing

 

Entanglement is generated 'naturally' when physical systems interact coherently. For example two electrons trapped at nearby sites can entangle with one another through their mutual Heisenberg interaction. This is the basis of many schemes for QIP, especially in the solid state. However, there is another route to entanglement: rather than allowing the physical qubits to interact directly, instead they can be kept at fixed, well separated sites and simply subjected to a measurement. The resulting paradigm of distributed QIP is increasingly perceived as an excellent prospect for a real practical technology. In this theoretical project we will examine a range of issues related to the distributed approach, from the physics of the individual subsystems through to the properties of the large scale entangled states which one would aim to create.
