Consider the subset of multipartite quantum operations that can be implemented when the parties are restricted to using local quantum operations and classical communication (LOCC). Besides technological motivations, questions concerning LOCC have inspired results including teleportation, entanglement distillation, and error correcting codes. We summarize recent results concerning LOCC -- in...

It is often said that quantum computers can achieve exponential speed-ups over classical computers and that quantum computers render RSA and other cryptographic protocols insecure. But how do quantum computers actually achieve this? I will describe the main ingredients that make these improvements possible and I will discuss the physical resources that are required to do so. I will also...

The epistemic view of the quantum state vector, according to which the state vector or wave function represents knowledge about a quantum system, rather than the true state of the system, goes back at least to Heisenberg. It has been revived and further developed in the past two decades, in the wake of the emergence of quantum information theory. Its sharpest formulation is Quantum...

Chaos in classical systems is characterized by extreme sensitivity of the dynamics to small perturbations. A corresponding characterization at the quantum level is challenging due to the uncertainty principle and the unitarity of quantum evolution. Here we explore how chaos can manifest itself in the quantum correlations between a collection of spin-1/2 systems or qubits. We present the first...
