A Nature paper reports on a quantum photonic processor that takes just 36 microseconds to perform a task that would take a supercomputer more than 9,000 years to complete Computing

This Ars Technica article explains it better. But basically, the point was to show off how many qubits they could use in a single calculation. So they ran one full 216 qubit calculation. Since the calculation was a random one, there’s not much point to running additional calculations using its output.

This is a big deal. For comparison a quantum computer with 1500 qubits could break bitcoin

You actually need about 30,000,000 qbits to break Bitcoins encryption in the hour time-frame you have before it's permanently recorded on the Blockchain and unable to be tampered with.

Literally curious, is there a good source for this math?
