Transmon-qubit readout using in-situ bifurcation amplification in the mesoscopic regime
R. Dassonneville, T. Ramos, V. Milchakov +8
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 transm…
Parallel tomography of quantum non-demolition measurements in multi-qubit devices
L. Pereira, J. J. García-Ripoll, T. Ramos
An efficient characterization of QND measurements is an important ingredient towards certifying and improving the performance and scalability of quantum processors. In this work, w…
Complete physical characterization of QND measurements via tomography
L. Pereira, J. J. García-Ripoll, T. Ramos
We introduce a self-consistent tomography for arbitrary quantum non-demolition (QND) detectors. Based on this, we build a complete physical characterization of the detector, includ…
Fast high fidelity quantum non-demolition qubit readout via a non-perturbative cross-Kerr coupling
R. Dassonneville, T. Ramos, V. Milchakov +12
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 transmo…
