Certification of Quantum Technologies
By Antonio Acín (ICFO)
Place: Aula Magna
Quantum technologies promise applications with no classical counterpart: more powerful computers or novel forms of encryption become possible when information is encoded on quantum systems. Given a quantum system, how can one ensure that it (i) is entangled? (ii) random? (iii) secure? (iv) performs a computation correctly? The concept of quantum certification embraces all these questions. It is crucial for the future development of quantum information technologies, but also goes at the heart of the fundamental question of what distinguishes quantum from classical physics. The talk first provides an introduction to the general problem of quantum certification and then focuses on methods for the certification of quantum cryptography protocols and quantum optimisers.
