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.

Strongly driven systems of emitters offer an attractive source of light over broad spectral ranges up to the X-ray region. A key limitation of these systems is that the light they emit is mostly classical. Pizzi et al. overcome this constraint by building a quantum-optical theory of strongly driven many-body systems, showing that the presence of correlations among the emitters creates emission of non-classical many-photon states of light.
