Quantum Journal Club: Quantum imaging with undetected photons
Abstract: Information is central to quantummechanics. In particular, quantum interference occurs only if there exists no information to distinguish between the superposed states. The mere possibility...

Quantum Control of Superconducting Circuits
Abstract: We develop an efficient scheme that allows for arbitrary operations on a cavity mode using a strongly dispersive qubit-cavity interaction and time-dependent drives. The scheme can readily b...

Entanglement in Fermionic Quantum Theory
Abstract: We review the framework of operational probabilistic theories, with particular emphasis on those notions that are related to the structure of composite systems. We then introduce the fermio...

Quantum Journal Club: Maxwell's Refrigerator: An Exactly Solvable Model
Abstract: We describe a simple and solvable model of a device that—like the ‘‘neat-fingered being’’ in Maxwell’s famous thought experiment—transfers energy from a cold system to a hot system b...

Quantum Cloning
Abstract: Giulio Chiribella will say a few words about the relation between quantum cloning and the distinguishability of quantum states, presenting, among other things, the solution of a previously ...
