MIT researchers designed an arm qubit architecture that lets qubits interact faster while staying highly stable.
MIT researchers designed an arm qubit architecture that lets qubits interact faster while staying highly stable.
The dual-purpose design pairs a data-storing component with an “arm” that couples to other qubits and electronics, using a quarton coupler for strong nonlinear coupling. Simulations show faster operations and readout with strong coherence versus other superconducting designs; the team next plans to fabricate the device.
