Quantum Memory Could Break Bitcoin and Replace It

A device called quantum memory has the potential to break Bitcoin and replace it with something better, according to an Oxford lecturer. Stefano Gogioso, a quantum computing expert at the University of Oxford, argues that the development of portable long-term quantum memory will be one of the most consequential milestones in quantum technology.

Gogioso says that this device will power new applications, including quantum money, which is essentially an ultimate digital store of value. He notes that while quantum computers can solve complex problems quickly, they are currently limited by their inability to hold fragile states for long periods of time.

The key to building a usable quantum memory device lies in achieving stability measured in months or even forever. This would allow for the creation of portable devices that could be used in various applications, including finance and cryptography.

Gogioso argues that the development of quantum memory is inevitable, as it is a necessary step towards building fault-tolerant quantum computers. He notes that billions of dollars are already committed to this technology, and that the memory device will sit at the heart of these machines.
