New quantum model cuts hardware needed to break bitcoin keys 17-fold

Researchers at Alice & Bob have developed a new model that substantially lowers the quantum hardware required for a potential attack on bitcoin cryptographic keys. The reduction, reported as roughly 17 times, moves such an attack closer to practical feasibility. The findings add urgency to the push for quantum-resistant security standards in the cryptocurrency ecosystem. Industry participants may therefore face greater pressure to adopt these protections sooner than previously planned. The development was reported by CoinDesk.
