A tunable-coupler unit cell for fluxonium qubits delivers parallel single-qubit gate fidelities near 99.99% and two-qubit CZ fidelities around 99%, validated by generating up to 10-qubit GHZ states in a 22-qubit processor.

Multimode strong coupling in circuit QED lattices produces emergent band gaps, lifted degeneracies, and a four-wave mixing process dominated by localized flat-band modes.
Microscopic unitary simulation of circuit QED readout shows qubit T1 drops with increasing drive amplitude when a Purcell notch filter is at the qubit frequency, exposing qualitative defects in Lindblad master equations.
Coupling a transmon to a multimode acoustic resonator achieves qubit reset with residual excited-state population below 10^{-4}.
