Qubit Architecture with High Coherence and Fast Tunable Coupling
Qubit Architecture with High Coherence and Fast Tunable Coupling
We introduce a superconducting qubit architecture that combines high-coherence qubits and tunable qubit-qubit coupling. With the ability to set the coupling to zero, we demonstrate that this architecture is protected from the frequency crowding problems that arise from fixed coupling. More importantly, the coupling can be tuned dynamically with nanosecond …
