Idex UCAJEDI Academy 1 organized a one-day workshop on quantum simulation, processing and communication. The event gathered scientists from quantum physics, photonics, computer science and telecommunications. About 40 people discussed the state of the art and perspectives for quantum technologies in the areas of computing, simulation and secured communications.

Location : Institut de Physique de Nice (InPhyNi), site Valrose, avenue Joseph Vallot, Nice.

9:00 Welcome coffee

9:30 Introduction to quantum information sciences: a spotlight on quantum photonics technologies (Olivier Alibart, UCA / INPHYNI)

We will provide an introduction on the quantum information and its applications. We will make an overview on quantum communication, metrology and processing for explaining what "quantum supremacy" means in term of information sciences. In the meantime, we will shine a spotlight on the quantum photonics approach (exploiting integrated optics and telecom technologies) providing naturally solutions to the quantum communication fields but also to the Q-metrology and Q-processing activities. This talk aims at providing a general background on quantum technologies.

10:15 Quantum Computing: Opportunities and Challenges for High Performance Computing (Simon Martiel, ATOS / Bull)

With Moore’s law reaching its slow but steady end, supercomputers need new fuel, since the need in HPC will keep increasing. Quantum computing seems appealing to take the succession. We will provide an overview of the promising results, as well as the challenges Science and Technology have to overcome to build these new machines.

11:00 Quantum information processing with superconducting quantum circuits (Denis Vion, CEA)

The concepts and implementation of quantum information processing  with superconducting electrical circuits will be presented to non-specialists.

14:00 Quantum Machine Learning algorithms (Iordanis Kerenidis, U. Paris Diderot)

Machine learning is one of the most promising applications of quantum algorithms. In this talk we will review some fundamental results in the area of Quantum Machine Learning and provide details about an application to Recommendation systems that runs exponentially faster than classical ones. We will also discuss the possibility of quantum algorithms for iterative methods.

14:45 Quantum-safe cryptography: answering the threat of the quantum computer on cybersecurity (Bruno Huttner, ID Quantique)

Over the last few years, the perceived threat of the quantum computer to the modern cryptographic standards in widespread use has increased dramatically. Our cyber security infrastructure has to be revamped and brought to a quantum-safe status. This means that we have to open our cryptographic toolbox and adapt our security infrastructure to new tools. In this presentation, we advocate the use of different types of tools for different types of applications. A single, one-size-fits-all, solution is not suitable. A combination of new Quantum-Resistant Algorithms (QRA's) and of Quantum Key Distribution (QKD) is well-adapted to the new challenges.

16:00 Distributing secret keys with quantum continuous variables (Anthony Leverrier, Inria)

The ability to distribute secret keys between two parties with information-theoretic security, that is regardless of the capacities of a malevolent eavesdropper, is one of the most celebrated results in the field of quantum information processing and communication. As with most quantum information protocols, quantum key distribution was first designed for qubits, the individual quanta of information. However, the use of quantum continuous variables for this task presents important advantages with respect to qubit-based protocols, in particular from a practical point of view, since it allows for simple implementations that require only standard telecommunication technology.
