Tunable Superconducting Flux Qubits with Long Coherence Times
Tunable Superconducting Flux Qubits with Long Coherence Times
In this work, we study a series of tunable flux qubits inductively coupled to a coplanar waveguide resonator fabricated on a sapphire substrate. Each qubit includes an asymmetric superconducting quantum interference device, which is controlled by the application of an external magnetic field and acts as a tunable Josephson junction. …
