Paragraph Title: … WebFeb 9, 2024 · Grover's algorithm will need to compute the hash function in superposition, and it needs to compute the entire hash function, whatever the nonce is. This means we need at least 512 qubits (256 for the input, 256 for the input) and in practice the number would be more like 5000 qubits.

WebJan 21, 2024 · The fact that pi shows up when we count the collisions is mirrored in the runtime of Grover’s algorithm: \frac {π} {4} \sqrt {N} steps. The square root in that expression also reflects how further digits of pi (in base 10) come from multiplying the mass of the big block by 100.
