Abstract

This year CERN celebrates its 70th Anniversary, and the 60th anniversary of Bell’s theorem, a result that arguably had the single strongest impact on modern foundations of quantum physics, both at the conceptual and methodological level, as well as at the level of its applications in information theory and technology.CERN with its Quantum Technology Initiative is looking into how this revolutionary technological change could align with CERN research and collaboration objectives. After a preliminary introduction about the promise of quantum technologies with focus on computing, we will discuss main research directions and results from theoretical foundations of quantum algorithms to application in several areas of High Energy Physics. //////////////////////////////////////// Speaker: Stefano Pirandola

Title: The Evolution of Quantum Networks Abstract: This seminar will present quantum networks as a sequence of successive technological developments, from near-term secure communication infrastructures to future distributed quantum computing platforms. We begin with quantum-safe networks, based on post-quantum cryptography or quantum key distribution, discussing their respective advantages, limitations, and deployment scenarios. We then consider cloud quantum computing, where multiple quantum processors are accessed classically and managed through workload orchestrators. The next stage is represented by quantum-networked clouds, in which local clusters of quantum computers are interconnected by quantum links, potentially involving transducers in hybrid architectures. Finally, we discuss distributed quantum clouds, where remote quantum computers are connected through quantum repeaters, opening the way to long-distance distributed quantum information processing.

Continuous-variable quantum communication

Tremendous progress in experimental quantum optics during the past decades enabled the advent of quantum technologies, one of which is quantum communication. Aimed at novel methods for more secure or efficient information transfer, quantum communication has developed into an active field of research and proceeds toward full-scale implementations and industrialization. Continuous-variable methods of multi-photon quantum state preparation, manipulation, and coherent detection, as well as the respective theoretical tools of phase-space quantum optics, offer the possibility to make quantum communication efficient, applicable and accessible, thus boosting the development of the field. We review the methodology, techniques and protocols of continuous-variable quantum communication, from the first theoretical ideas, through milestone implementations, to the recent developments, covering quantum key distribution as well as other quantum communication schemes, suggested on the basis of continuous-variable states and measurements.
