Quantum computing may seem like science fiction, but it may come sooner than expected.

On Jan. 11, 2024, the World Economic Forum identified artificial intelligence and quantum computing as emerging threats in a report exploring how quantum computing could threaten the existing tech landscape. While computer scientists and developers agree that quantum computing will still take some years to develop, research in the field is very active. In the public sector, all G7 countries are actively involved in quantum computing projects.

For Buterin, the technology required to make Ethereum immune to a quantum attack could be developed “tomorrow”: We are already well-positioned to make a pretty simple recovery fork to deal with such a situation. Buterin’s proposed solution is based on proving ownership of crypto assets or a wallet by applying a backup key as a fallback.

The end of the quantum tunnel: Exact instanton transseries for quantum mechanicsThe end of the quantum tunnel: Exact instanton transseries for quantum mechanicsIn the quantum world, processes can be separated into two distinct classes. One class, that of the so-called 'perturbative' phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation.
