Oxford Researcher Proposes Quantum Memory as Long-Term Threat to Bitcoin Cryptography

Stefano Gogioso, a quantum computing lecturer at the University of Oxford and co-founder of Spooqy, argues that the realization of long-term quantum memory will determine whether Bitcoin's cryptographic foundations fail or are replaced by quantum-native currency.

According to Gogioso, quantum money is inherently counterfeit-proof due to the physical impossibility of copying quantum states, but current laboratory systems can only sustain these states for seconds. A functional quantum currency would require memory capable of holding billions of states in sequence for months or longer, while evolving from crate-sized hardware to pocket-sized devices.

Gogioso contends that quantum memory is an inevitable byproduct of broader research into fault-tolerant quantum computing, which requires protecting fragile states from noise. Rather than relying solely on cryogenic systems, atom-based storage designs isolate quantum properties naturally, turning memory retention into an engineering challenge rather than a theoretical physics limitation.
