"single layer of qubits atop several layers of control wiring, which helps cram more qubits in while reducing their error rate. An integrated filtering system has now been added, which helps reduce noise and improve stability of the device. IBM says this machine’s number-crunching capabilities far surpass any traditional computer, claiming that to represent a state on the Osprey processor, a regular computer would need more bits than there are atoms in the known universe"
