Building a utility scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesnt require nearly the resources anticipated just a year or two ago, two independently written whitepapers have concluded. In one, researchers demonstrated the use of neutral atoms as reconfigurable qubits that have free access to each other. They went on to show this approach could allow a quantum computer to break 256 bit elliptic curve cryptography ECC in 10 days while using 100...
