Isotopic control of the boron-vacancy spin defect in hexagonal boron nitride
T. Clua-Provost, A. Durand, Z. Mu +12
We report on electron spin resonance (ESR) spectroscopy of boron-vacancy (V) centers hosted in isotopically-engineered hexagonal boron nitride (hBN) crystals. We first…
Optically-active spin defects in few-layer thick hexagonal boron nitride
A. Durand, T. Clua-Provost, F. Fabre +11
Optically-active spin defects in hexagonal boron nitride (hBN) are promising quantum systems for the design of two-dimensional quantum sensing units offering optimal proximity to t…
Detection of single W-centers in silicon
Yoann Baron, Alrik Durand, Péter Udvarhelyi +13
Controlling the quantum properties of individual fluorescent defects in silicon is a key challenge towards advanced quantum photonic devices prone to scalability. Research efforts…
Single photon wavefront-splitting interference: An illustration of the light quantum in action
V. Jacques, E. Wu, T. Toury +4
We present a new realization of the textbook experiment consisting in single-photon interference based on the pulsed, optically excited photoluminescence of a single colour centre…
Broad diversity of near-infrared single-photon emitters in silicon
A. Durand, Y. Baron, W. Redjem +11
We report the detection of individual emitters in silicon belonging to seven different families of optically-active point defects. These fluorescent centers are created by carbon i…
Coherent Population Trapping with a controlled dissipation: applications in optical metrology
L. Nicolas, T. Delord, P. Jamonneau +4
We analyze the properties of a pulsed Coherent Population Trapping protocol that uses a controlled decay from the excited state in a -level scheme. We study this problem analyti…
