Two groups have made laser based Quantum computers able to run Shor’s algorithm, which would let them break financial encryption. It would take about two qubits per bit of encryption. 1024 bit encryption would need 2048 qubits to break.
There are algorithms for encryption which would be resistant to Shor’s algorithm on quantum computers. So we would still be able to encrypt financial transactions.
