Journal Club Winter 2013
This season we will be focusing on quantum information theory. Classical information theory is ubiquitous in science and mathematics with applications ranging from characterizing ensembles of particles to answering how many bits can be sent reliably over a noisy channel. It is even useful as an estimation technique for gauging the difficulty of a research problem. For instance, one may ask, how many bits are necessary to specify a quantum circuit acting on n bits(with bit flips Toffoli and Hadamard gates) and how does that compare to the number of bits required to specify a classical circuit(just bit flips and Tofolli gates)? This question already leads to a naive bound on the average quantum speed-up attainable over classical circuits, e.g. there isn't enough information in the specification of constant depth quantum circuits to characterize all reversible function on n-bits and so we conclude that there are deterministic functions that require more than constant quantum depth. Although this example is rather simple, it already gives the researcher some perspective about a very broad and difficult problem, that of finding quantum speed-ups. If classical information theory can quickly give us insight into the classical resources needed for a task, perhaps quantum information theory would be equally useful in giving us insight into the quantum resources needed for a quantum task?
