Improved Superconducting Qubit Readout by Qubit-Induced Nonlinearities
Maxime Boissonneault, J. M. Gambetta, Alexandre Blais
In dispersive readout schemes, qubit-induced nonlinearity typically limits the measurement fidelity by reducing the signal-to-noise ratio (SNR) when the measurement power is increa…
Control and Tomography of a Three Level Superconducting Artificial Atom
R. Bianchetti, S. Filipp, M. Baur +6
A number of superconducting qubits, such as the transmon or the phase qubit, have an energy level structure with small anharmonicity. This allows for convenient access of higher ex…
Electromagnetically-induced transparency with amplification in superconducting circuits
Jaewoo Joo, Jerome Bourassa, Alexandre Blais +1
We show that electromagnetically-induced transparency and lasing without inversion are simultaneously achieved for microwave fields by using a fluxonium superconducting circuit. As…
Schemes for the observation of photon correlation functions in circuit QED with linear detectors
Marcus P. da Silva, Deniz Bozyigit, Andreas Wallraff +1
Correlations are important tools in the characterization of quantum fields. They can be used to describe statistical properties of the fields, such as bunching and anti-bunching, a…
