They caused a billion-billion custom-designed molecules in a test tube to become a seven-qubit quantum computer that solved a simple version of the mathematical problem at the heart of many of today's data-security cryptographic systems.

No, no van mal, pero lo máximo que hasta ahora se ha podido manejar son 7-qubits, lo que dista mucho de ser una computadora cuántica útil.
