Where's mick?

Following the example of Dave I thought I'd start posting my travel plans for all the world to see.

For the next week or so I'll be heading to the UK. I will be traveling to Bristol for an interview and will be there till the weekend. After that I'll be in London where I will catch up with a whole bunch of people and maybe sneak in a little research on the side.

On Thursday I'm giving a talk to the quantum information theory group at the University of Bristol. If any of you are interested the title and the abstract can be found below:

Title: To what extent can one quantum system simulate another?


Quantum computers are an example of a large class of quantum-control systems that are capable of simulating the Hamiltonian dynamics of any finite-dimensional system. It turns out that many such systems have the same computational power as a quantum computer, at least when one assumes perfect control operations. For some simulation problems this is a blessing, as in when you want to simulate the dynamics of a k-local Hamiltonian, and for others this is a curse, for instance when you want to find spectral information of a k-local Hamiltonian. In this talk I will discuss some of the key challenges ahead in the field of quantum simulation, in particular I will focus on the problem of identifying systems that are universal for quantum computation (and simulation) and on the effects of noise on certain quantum simulation protocols.
