BTQ Technologies and QPerfect Deliver First Circuit-Level Implementation of Quantum One-Shot Signatures
TL;DRCompanies built a working quantum signature system that's secure after one use, no blockchain needed.
Why it matters: Quantum signatures could replace blockchain for security-critical transactions, potentially faster and more efficient.
BTQ Technologies and QPerfect have developed a circuit-level implementation of a quantum one-shot signature (OSS) scheme. This scheme uses fragile quantum states to ensure single-use security, eliminating the need for blockchains. Their approach streamlines previous theoretical…
