Transmon-qubit readout using in-situ bifurcation amplification in the mesoscopic regime

Autor: Dassonneville, R., Ramos, T., Milchakov, V., Mori, C., Planat, L., Foroughi, F., Naud, C., Hasch-Guichard, W., Garcia-Ripoll, J. J., Roch, N., Buisson, O.

Publikováno v: Phys. Rev. Applied 20, 044050 (2023)

We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transmon molecule consisting of a transmon qubit and an ancilla mode interac

Propagating Quantum Microwaves: Towards Applications in Communication and Sensing

Publikováno v: Quantum Sci. Technol. 8 (2), 023001 (2023)

The field of propagating quantum microwaves has started to receive considerable attention in the past few years. Motivated at first by the lack of an efficient microwave-to-optical platform that could solve the issue of secure communication between r

Dissipative stabilization of squeezing beyond 3 dB in a microwave mode

Autor: Dassonneville, R., Assouly, R., Peronnin, T., Clerk, A. A., Bienfait, A., Huard, B.

Publikováno v: PRX Quantum 2, 020323 (2021)

While a propagating state of light can be generated with arbitrary squeezing by pumping a parametric resonator, the intra-resonator state is limited to 3 dB of squeezing. Here, we implement a reservoir engineering method to surpass this limit using s

Fast high fidelity quantum non-demolition qubit readout via a non-perturbative cross-Kerr coupling

Autor: Dassonneville, R., Ramos, T., Milchakov, V., Planat, L., Dumur, É., Foroughi, F., Puertas, J., Leger, S., Bharadwaj, K., Delaforce, J., Naud, C., Hasch-Guichard, W., García-Ripoll, J. J., Roch, N., Buisson, O.

Publikováno v: Phys. Rev. X 10, 011045 (2020)

Qubit readout is an indispensable element of any quantum information processor. In this work, we experimentally demonstrate a non-perturbative cross-Kerr coupling between a transmon and a polariton mode which enables an improved quantum non-demolitio
