A high on-off ratio beamsplitter interaction for gates on bosonically encoded qubits
Benjamin J. Chapman, Stijn J. de Graaf, Sophia H. Xue +12
Encoding a qubit in a high quality superconducting microwave cavity offers the opportunity to perform the first layer of error correction in a single device, but presents a challen…

Precision measurement of the microwave dielectric loss of sapphire in the quantum regime with parts-per-billion sensitivity
Alexander P. Read, Benjamin J. Chapman, Chan U Lei +5
Dielectric loss is known to limit state-of-the-art superconducting qubit lifetimes. Recent experiments imply upper bounds on bulk dielectric loss tangents on the order of par…
