"Quantum metrology and creating the quantum resources for it" - C1, 3pm

Quantum information technologies (QIT) offer advantages over their conventional IT counterparts, due to exploitation of fundamental features of quantum physics such as entanglement. Quantum communication technologies are now available, whereas large scale quantum computers are still a long way off. Measurement and sensing technologies, based on modest and practical quantum resources, could be the next QIT to emerge commercially. In this talk I'll give a simple review of the ideas that underpin quantum metrology. A key issue for metrology is the preparation of suitable quantum resources.

I'll highlight two examples of such resource preparation:

(i) Collapse and revival and cat state preparation in spin systems.

(ii) "Cooling" a superconducting device into a cat state.
