Maxwell’s demon with a Szilard box, as proposed by Bennett. A measurement detects on which side of the inserted separator the particle is, and extracts work with a piston in either case. The cylinder is left in its original state, apparently creating a perpetuum mobile with net work gain. However, the measurement outcome (represented by ‘L’ or ‘R’) had to be stored in a memory register, which was initially in some pure state (represented by ‘—’) and the work cost of resetting it to a pure state again compensates the work gain.

New Paper out in CMP

Don’t miss out on our latest CMP paper. We recently derived extensions of the Golden-Thompson inequality to arbitrarily many matrices. We show how spectral pinching and complex interpolation theory can be used to prove matrix inequalities. Such inequalities sharpen our understanding of the laws of quantum mechanics. Read more
