When will Bitcoin be broken?
To break RSA-3072 encryption theoretically requires 3,072 pure qubits—entangled bits. That’s how many are needed for the quantum Fourier transform to operate on a 3,072-bit number. That’s what Shor’s algorithm requires to break such encryption. RSA-3072 bits are equivalent to ECC 256 bits, which is the security level of Bitcoin. Currently, there are quantum chips …
