Certification of quantum technologies

Antonio Acín

ICFO-The Institute of Photonic Sciences, Barcelona

Quantum information 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) and 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.
