If you have a question about this talk, please contact Ashley Montanaro. I will talk about two recent projects: 1) An experiment-friendly method of implementing quantum computation, called Ancilla-Driven Quantum Computation (ADQC), where the computation on a static register of qubits is driven remotely with the help of a single, flying ancilla qubit that “steers” the evolution of the register. Refs: Janet Anders, Daniel K. L. Oi, Elham Kashefi, Dan E. Browne, Erika Andersson, Phys. Rev. A 82 , 020301® (2010); a technical discussion can be found at arXiv:0905.3354v2 2) I will then review Landauer’s erasure principle. In the last decade a number of papers and books have claimed violation of Landauer’s principle (and the 2nd law of thermodynamics) in the strongly coupled quantum regime. I will argue why these claims are erroneous and show how a consistent treatment resolves the paradox.
