DESCRIPTION:Quantum systems carry an intrinsically quantum form of informa
 tion\, which cannot be copied and allows much stronger control than classi
 cal information.  Special relativity also allows the flow of information t
 o be controlled through the no-superluminal signalling principle.   Togeth
 er these have led to the emerging science and technology of relativistic q
 uantum cryptography.   I describe some applications\, including verifying 
 the location of a prisoner\, using quantum teleportation to fake anything\
 , running a secure quantum casino\, guaranteeing trust in untrustworthy cr
 yptographic device builders\, and using quantum theory to decline party in
 vitations with guaranteed tact.   I also describe the first relativistic q
 uantum cryptographic experiment\, carried out recently by a Geneva-Singapo
 re-Cambridge collaboration.
