Transit effects for non-linear index measurement in hot atomic vapors
Tangui Aladjidi, Murad Abuzarli, Guillaume Brochier +4
Hot atomic vapors are widely used in non-linear and quantum optics due to their large Kerr non-linearity. While the linear refractive index and the transmission are precisely measu…
QND measurement of a superconducting qubit in the weakly projective regime
T. Picot, R. Schouten, C. J. P. M. Harmans +1
Quantum state detectors based on switching of hysteretic Josephson junctions biased close to their critical current are simple to use but have strong back-action. We show that the…
Role of relaxation in the quantum measurement of a superconducting qubit using a nonlinear oscillator
T. Picot, A. Lupascu, S. Saito +2
We analyze the relaxation of a superconducting flux qubit during measurement. The qubit state is measured with a nonlinear oscillator driven across the threshold of bifurcation, ac…
Interqubit coupling mediated by a high-excitation-energy quantum object
S. Ashhab, A. O. Niskanen, K. Harrabi +6
We consider a system composed of two qubits and a high-excitation-energy quantum object used to mediate coupling between the qubits. We treat the entire system quantum mechanically…
Quantum non-demolition measurement of a superconducting two-level system
A. Lupascu, S. Saito, T. Picot +3
In quantum mechanics, the process of measurement is a subtle interplay between extraction of information and disturbance of the state of the quantum system. A quantum non-demolitio…
