In a future where quantum computers will break much current cryptography, quantum communications offers the potential for unbreakable security, through untappable distribution of secret keys over optical fibres and free space, including satellite communications. This panel will take stock of the huge, current world-wide interest in and funding of quantum communications programs including developments in the US, China, Japan and Europe.
What will be the killer applications of quantum communications –will it be for bespoke point to point short-haul secure systems or can it form the basis of unprecedented long-lived security solutions even enabling data storage? Will it extend to core and access networks? Will quantum satellites create secure international communications or will classical, quantum-safe cryptography render quantum communications obsolete before it even starts?
