Two new academic studies downplay quantum threats to Bitcoin, proving that an attack on mining is physically unfeasible.

Two recent academic papers, shared on X by NVK, offer a far more sober picture than the alarmist headlines that periodically rattle crypto markets. The first study, authored by Pierre-Luc Dallaire-Demers and the team at BTQ Technologies and published in March 2026, analyzes the feasibility of a quantum attack on Bitcoin mining. The second, authored by Peter Gutmann of the University of Auckland and Stephan Neuhaus of the Zürcher Hochschule in Switzerland, systematically dismantles every alleged quantum factorization “breakthrough” of the past twenty years.

Bitcoin’s security relies on two distinct types of cryptography, and quantum computers threaten them in different ways. Shor’s algorithm targets wallet security: in theory, it would allow a sufficiently powerful quantum computer to derive a private key from a public key, enabling an attacker to seize funds. Grover’s algorithm, on the other hand, applies to mining, offering a theoretical speedup in the search process that miners perform to find valid blocks. These two threats are often conflated in newspaper headlines, but they carry very different implications once real physical limitations are taken into account.
