Left: a fully assembled quantum system at Google Quantum AI; prominently displayed is the dilution refrigerator in which the computations occur, the quantum processor and quantum-limited amplifiers installed at the bottom stage of the refrigerator, various cables connecting bottom to top, and control electronics of quantum computer in the back. Right: two generations of Sycamore processors fabricated by Google Quantum AI; each processor features two chips that are bonded together: a chip containing the quantum bits (qubits), and a chip containing the wiring between the qubits and the outside world; the latest generation of the Sycamore processor on the right is notably larger than previous generations, but also has several modifications to the qubits resulting in improved performance.
