The Department of Applied Mathematics at H.I.T. – Holon Institute of Technology (Holon, Israel) invites applications for a postdoctoral position in Mathematical Physics. The successful candidate is expected to be involved into a research at the crossroad of the Random Matrix Theory, Quantum Chaotic Systems, and the Theory of Integrable Hierarchies. Previous research record in one of those fields is an advantage, strong analytical skills is a must.

Quantum Information Theory is the study of information-processing tasks such as storage and transmission of information, or manipulation of entanglement, using quantum-mechanical systems. Until very recently, the study of these processes was limited to the case in which the required resources, e.g. information sources, communication channels or entanglement resources, were assumed to be available for an infinite number of independent uses.

We prove that the optimal strategy to store an unknown group transformation into a quantum memory is to apply the available uses in parallel on a suitable entangled state. The optimal retrieving strategy is the incoherent, ``measure-and-rotate'' strategy, in which the quantum memory is measured and a unitary depending on the outcome is performed. The same result holds for approximate re-alignment of reference frames for quantum communication.

Postdoctoral Research Associate (Fixed term until 31 August 2012)

Mathematical Quantum Control

Institute of Mathematics and Physics

Grade 7: £30,594 - £35,469

Applications are invited for a postdoctoral research associate position at Aberystwyth University. The successful candidate will work on an EPSRC funded project on theoretic methods applied to quantum control, and will work with the Quantum Open Systems and Control research group at Aberystwyth.

We introduce the quantum stochastic walk (QSW), which determines the evolution of generalized quantum mechanical walk on a graph that obeys a quantum stochastic equation of motion. Using an axiomatic approach, we specify the rules for all possible quantum, classical and quantum-stochastic transitions of a vertex as defined from its connectivity. We show how the family of possible QSW encompasses both the classical random walk (CRW) and the quantum walks (QW) as special cases, but also includes more general probability distributions.

The difficulty in producing precisely timed and controlled quantum gates is a significant source of error in many physical implementations of quantum computers. Here we introduce a simple universal primitive, adiabatic gate teleportation, which is robust to timing errors and many control errors and maintains a constant energy gap throughout the computation above a degenerate ground state space. Notably this construction allows for geometric robustness based upon the control of two independent qubit interactions.
