High coherence hybrid superconducting qubit
We measure the coherence of a new superconducting qubit, the {\em
low-impedance flux qubit}, finding s. It is a
three-junction flux qubit, but the ratio of junction critical currents is
chosen to make the qubit's potential have a single well form. The low impedance
of its large shunting capacitance protects it from decoherence. This qubit has
a moderate anharmonicity, whose sign is reversed compared with all other
popular qubit designs. The qubit is capacitively coupled to a high-Q resonator
in a configuration, which permits the qubit's state to be read out
dispersively

A simple all-microwave entangling gate for fixed-frequency superconducting qubits
We demonstrate an all-microwave two-qubit gate on superconducting qubits
which are fixed in frequency at optimal bias points. The gate requires no
additional subcircuitry and is tunable via the amplitude of microwave
irradiation on one qubit at the transition frequency of the other. We use the
gate to generate entangled states with a maximal extracted concurrence of 0.88
and quantum process tomography reveals a gate fidelity of 81%
