Addressing a single NV spin with a macroscopic dielectric microwave cavity
J. -M. Le Floch, C. Bradac, N. Nand +3
We present a technique for addressing single NV center spins in diamond over macroscopic distances using a tunable dielectric microwave cavity. We demonstrate optically detec…
Strong Coupling Between P1 Diamond Impurity Centres and 3D Lumped Photonic Microwave Cavity
Daniel L. Creedon, Jean-Michel Le Floch, Maxim Goryachev +3
We report strong coupling between an ensemble of N impurity (P1) centres in diamond and microwave photons using a unique double post re-entrant cavity. The cavity is designed so th…
Piezoelectric Voltage Coupled Reentrant Cavity Resonator
Natalia C. Carvalho, Yaohui Fan, Jean-Michel Le Floch +1
A piezoelectric voltage coupled microwave reentrant cavity has been developed. The central cavity post is bonded to a piezoelectric actuator allowing the voltage control of small p…
Evidence of Dilute Ferromagnetism in Rare-Earth doped YAG
W. G. Farr, M. Goryachev, J. M. le Floch +2
This work demonstrates strong coupling regime between an Erbium ion spin ensemble and microwave Hybrid Cavity-Whispering Gallery Modes in a Yttrium Aluminium Garnet dielectric crys…
Hyperparametric effects in a whispering-gallery mode rutile dielectric resonator at liquid helium temperatures
Nitin R. Nand, Maxim Goryachev, Jean-Michel Le Floch +2
We report the first observation of low power drive level sensitivity, hyperparametric amplification, and single-mode hyperparametric oscillations in a dielectric rutile whispering-…
Strong Coupling Between Whispering Gallery Photons and Spin States of Iron Group Impurity Ions
Maxim Goryachev, Warrick G. Farr, Natalia C. Carvalho +5
Interaction of Whispering Gallery Modes (WGM) with dilute spin ensembles in solids is an interesting paradigm of Hybrid Quantum Systems potentially beneficial for Quantum Signal Pr…
3D Cavity quantum electrodynamics with a rare-earth spin ensemble
S. Probst, A. Tkalcec, H. Rotzinger +6
We present cavity QED experiments with an Er:YSO crystal magnetically coupled to a 3D cylindrical sapphire loaded copper resonator. Such waveguide cavities are promising for the re…
