This is a resource-estimate and circuit design from a preprint, validated only on an emulator, not on hardware. The 206 to 2,438 logical qubit requirement puts practical deployment well beyond current machines, and the authors note that the classical obfuscation layer the scheme depends on remains unresolved. For readers tracking quantum security, the main value is the concrete circuit blueprint for blockchain-free, single-use signatures, not any near-term capability.
BTQ Technologies and QPerfect Deliver First Circuit-Level Implementation of Quantum One-Shot Signatures

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 frameworks by using a puncturable pseudorandom function and a global measurement routine for multi-bit signing. The post BTQ Technologies and QPerfect Deliver First Circuit-Level Implementation of Quantum One-Shot Signatures appeared first on Quantum Computing Report.
Researchers from BTQ Technologies and its French subsidiary QPerfect have published an explicit, circuit-level implementation of a one-shot signature (OSS) scheme in a preprint titled A quantum algorithm for one-shot signatures. The work translates theoretical protocols into concrete quantum gate instructions,…
