Quantum Enhanced Measurement of an Optical Frequency Comb
Y. Cai, J. Roslund, V. Thiel +2
Measuring the spectral properties of an optical frequency comb is among the most fundamental tasks of precision metrology. In contrast to general single-parameter measurement schem…
Modal analysis of noise propagation in a femtosecond oscillator
Syamsundar De, Valérian Thiel, Jonathan Roslund +2
We study noise propagation dynamics in a femtosecond oscillator by injecting external noise on the pump intensity. We utilize a spectrally-resolved homodyne detection technique tha…
Quantum-limited measurements of distance fluctuations with a multimode detector
Valérian Thiel, Jonathan Roslund, Pu Jian +2
An experimental scheme is introduced to measure multiple parameters that are encoded in the phase quadrature of a light beam. Using a modal description and a spectrally-resolved ho…
On the Theoretical Capacity of Evolution Strategies to Statistically Learn the Landscape Hessian
Ofer M. Shir, Jonathan Roslund, Amir Yehudayoff
We study the theoretical capacity to statistically learn local landscape information by Evolution Strategies (ESs). Specifically, we investigate the covariance matrix when construc…
Reconfigurable Optical Quantum Networks Using Multimode Quantum Frequency Combs and Pulse Shaping
Y. Cai, J. Roslund, G. Ferrini +4
Multimode entanglement is quintessential for the design and fabrication of quantum networks, which play a central role in quantum information processing and quantum metrology. Howe…
Absolute Measurement of Quantum-Limited Interferometric Displacements
Valérian Thiel, Pu Jian, Claude Fabre +2
A methodology is introduced that enables an absolute, quantum-limited measurement of sub-wavelength interferometric displacements. The technique utilizes a high-frequency optical p…
