Two-colour high-purity Einstein-Podolsky-Rosen photonic state
Tulio Brito Brasil, Valeriy Novikov, Hugo Kerdoncuff +2
Entanglement is the backbone of quantum information science and its applications. Entangled states of light are necessary for distributed quantum protocols, quantum sensing and qua…
Quantum frequency conversion of vacuum squeezed light to bright tunable blue squeezed light and higher-order spatial modes
Hugo Kerdoncuf, Jesper B. Christensen, Mikael Lassen
Quantum frequency conversion, the process of shifting the frequency of an optical quantum state while preserving quantum coherence, can be used to produce non-classical light at ot…
Quantum-Enhanced continuous-wave stimulated Raman spectroscopy
R. B. Andrade, H. Kerdoncuff, K. Berg-Sørensen +3
Stimulated Raman spectroscopy has become a powerful tool to study the spatiodynamics of molecular bonds with high sensitivity, resolution and speed. However, sensitivity and speed…
Cavity-enhanced sum-frequency generation of blue light with near-unity conversion efficiency
Hugo Kerdoncuff, Jesper B. Christensen, Túlio B. Brasil +4
We report on double-resonant highly efficient sum-frequency generation in the blue range. The system consists of a 10-mm-long periodically poled KTP crystal placed in a double-reso…
Continuous-wave coherent Raman spectroscopy for improving the accuracy of Raman shifts
Hugo Kerdoncuff, Mikael Lassen, Jan C. Petersen
Raman spectroscopy is an appealing technique that probes molecular vibrations in a wide variety of materials with virtually no sample preparation. However, accurate and reliable Ra…
Squeezing-enhanced measurement sensitivity in a cavity optomechanical system
Hugo Kerdoncuff, Ulrich B. Hoff, Glen I. Harris +2
We determine the theoretical limits to squeezing-enhanced measurement sensitivity of mechanical motion in a cavity optomechanical system. The motion of a mechanical resonator is tr…
Compact and versatile laser system for polarization-sensitive stimulated Raman spectroscopy
Hugo Kerdoncuff, Mark R. Pollard, Philip G. Westergaard +2
We demonstrate a compact and versatile laser system for stimulated Raman spectroscopy (SRS). The system is based on a tunable continuous wave (CW) probe laser combined with a home-…
Quantum enhanced feedback cooling of a mechanical oscillator
Clemens Schäfermeier, Hugo Kerdoncuff, Ulrich B. Hoff +7
Laser cooling is a fundamental technique used in primary atomic frequency standards, quantum computers, quantum condensed matter physics and tests of fundamental physics, among oth…
Quantum-enhanced micro-mechanical displacement sensitivity
Ulrich B. Hoff, Glen I. Harris, Lars S. Madsen +5
We report on a hitherto unexplored application of squeezed light: for quantum-enhancement of mechanical transduction sensitivity in microcavity optomechanics. Using a toroidal sili…
