"Flying and stationary qubits – a cascaded systems approach"

Speaker: Prof. Klaus Mølmer

(Niels Bohr Institute)

Abstract:

With the scaling of quantum technologies to many separate material quantum

components, we may have recourse to couple these systems by quantum radiation

of light, microwaves or phonons. In future optical quantum processors, we may,

conversely, need to manipulate the quantum states of radiation pulses by their

interaction with non-linear stationary quantum components. Several physical

processes have been proposed and already demonstrated for these tasks.

There are, however, rather fundamental obstacles to the treatment of propagation

of radiation in circuits for quantum computing. These obstacles include the general

multimode character of propagating fields and the duration and spatial extent of

useful light and microwave pulses. The talk will review recent developments of a

cascaded master equation approach to deal theoretically with these obstacles, and

it will present examples of new, unforeseen, possibilities for easy preparation and

manipulation “on the fly” of quantum states of light and matter.
