Grover's Algorithm - a threat to blockchain that is not commonly discussed

Microsoft and Atom Computing have announced a significant breakthrough in quantum computing that could change the approach to Proof-of-Work in blockchain mining. The developed quantum computing-based system includes 24 logical qubits, created using only 80 physical qubits. This is a new record, demonstrating the efficiency of error correction and significantly surpassing previous estimates, which stated that creating one logical qubit required thousands of physical qubits.

Such an achievement changes the perception of the scalability of quantum systems. The ability to form 24 logical qubits with minimal resources accelerates the development of technologies, bringing closer the commercial implementation of quantum computing systems.

The development of quantum technologies is also of interest in the context of cryptography and blockchains. For example, the SHA-256 algorithm used by networks like Bitcoin may be threatened by quantum computers. This algorithm serves as the basis for the tasks that miners solve,
