Research Interests
Quantum information theory, quantum computing and quantum cryptography. I study the absolute limits that physics places on information processing, and how to exploit physical effects to accomplish otherwise impossible communication and computing tasks.

Selected Recent Papers
* Quantum computation vs. firewalls
* Two-message quantum interactive proofs and the quantum separability problem
* Summoning information in spacetime, or where and when can a qubit be?
* Information trade-offs for optical quantum communication
* Towards the fast scrambling conjecture
* Holographic mutual information is monogamous
* From low-distortion norm embeddings to explicit uncertainty relations and efficient information locking
* Weak decoupling duality and quantum identification
* Black holes as mirrors: Quantum information in random subsystems
* Counterexamples to the maximal p-norm multiplicativity conjecture for all p > 1

Prospective Students
I am currently recruiting M.Sc. and Ph.D. students. If you love computer science, mathematics and physics, and have a strong background in at least two of them, please apply!
