Sequential dispersive measurement of a superconducting qubit
Théau Peronnin, Danijela Marković, Quentin Ficheux +1
We present a superconducting device that realizes the sequential measurement of a transmon qubit. The device disables common limitations of dispersive readout such as Purcell effec…

Demonstration of an effective ultrastrong coupling between two oscillators
Danijela Marković, Sébastien Jezouin, Quentin Ficheux +6
When the coupling rate between two quantum systems becomes as large as their characteristic frequencies, it induces dramatic effects on their dynamics and even on the nature of the…
