The company estimates developing quantum applications to detect fraud and cybersecurity. Qubits are the information processing unit for quantum computers. The Oxford Quantum Circuit (OQC) company announced on June 5 that it intends to revolutionize the scalability of quantum computing. By the year 2028, OQC plans to reach 200 logical qubits and by 2034, the goal is more ambitious: 50,000 logical qubits on quantum computers. These figures, according to the report of the British company that emerged from the University of Oxford, exceed more than «10 times in the efficiency of physical qubits.» As described by Oxford Quantum Circuit, the purpose will be to use quantum computing for fraud detection fraud detection, cybersecurity and the development of new medications, prioritizing sectors such as finance, defense and security.
Authorities think about quantum and bitcoin
Adam Back, co -founder of blockstream, a company that develops technologies linked to Bitcoin, said ECDSA would require a quantum system with «300 million physical qubits» And a correction of errors that currently do not exist, estimating that, at the current rhythm, this could take about 50 years, according to Back. Since Back refers to the amount of physical qubits, it is necessary to approach a notion of how many of those qubits are necessary to build a logical qbit (those pointed out by the OQC report). An April 2025 analysis of the Post Quantum specialized site explains that the conversion of physical to logical qubits has a high computational cost: each logical qubit may require hundreds or thousands of physical qubits. For example, according to Post Quantum data, a Google logical qbit prototype used 49 Qubits physicists to encode one QUBIT logicalwhile, in less efficient systems, this proportion reaches 1,000 physical qubits per logical qbit. Using as a reference that last figure of «1,000 physical qubits per logical qbit», oxford quantum circu ECDSA. In line with Back's vision, a study by the University of Sussex reported by cryptootics calculated that 13 million physical qubits would be needed To compromise Bitcoin's encryption in one day, a number that, using the optimized OQC proportion, would be equivalent to some 130,000 logical qubits (13,000,000 ÷ 100). Charles Guillemet, CTO of Ledger, also minimized the current risks. In response to a Google report on quantum advances, he affirmed that «a machine with millions of stabilized and corrected rates of errors» would be needed to represent a real threat. «We are not even close to that,» he emphasized, highlighting the current technological limitations. In this way, compared to these estimates of experts, the 50,000 logical OQC qubits by 2034, allegedly equivalent to 5 million physical qubits, They would still be below of the 13 million necessary physical qubits according to Sussex. Therefore, despite the advances promised by companies such as OQC, the quantum threat for Bitcoin seems, for now, A distant challengegiving time to the ecosystem to develop solutions such as algorithms resistant to quantum computing.
