Defects in hexagonal boron nitride for quantum technologies
Tobias Vogl, Viktor Ivády, Isaac J. Luxmoore +1
Atomic defects in solid-state materials are building blocks for future quantum technologies, such as quantum communication networks, computers, and sensors. Until recently, a handf…
Stimulated Emission Depletion Microscopy with Color Centers in Hexagonal Boron Nitride
Prince Khatri, Ralph Nicholas Edward Malein, Andrew J. Ramsay +1
Stimulated emission depletion, or STED microscopy is a well-established super-resolution technique, but is ultimately limited by the chosen flourophore. Here we demonstrate STED mi…
Stimulated emission depletion spectroscopy of color centers in hexagonal boron nitride
Ralph N. E. Malein, Prince Khatri, Andrew J. Ramsay +1
We demonstrate the use of Stimulated Emission Depletion (STED) spectroscopy to map the electron-optical-phonon sideband of the ground state of the radiative transition of color cen…
Optical control of the charge state of color centers in hexagonal boron nitride
Prince Khatri, Andrew J. Ramsay, Ralph N. E. Malein +2
We report on multicolor excitation experiments with color centers in hexagonal boron nitride at cryogenic temperatures. We demonstrate controllable optical switching between bright…
Phonon sidebands of color centers in hexagonal boron nitride
P. Khatri, I. J. Luxmoore, A. J. Ramsay
Low temperature photoluminescence spectra of a color center in hexagonal boron nitride are analyzed. The acoustic phonon sideband can be described by a deformation coupling proport…
Strong coupling in the far-infrared between graphene plasmons and the surface optical phonons of silicon dioxide
Isaac. J. Luxmoore, Choon How Gan, Peter Q. Liu +4
We study plasmonic resonances in electrostatically gated graphene nanoribbons on silicon dioxide substrates. Absorption spectra are measured in the mid-far infrared and reveal mult…
III-V quantum light source and cavity-QED on Silicon
Isaac J. Luxmoore, Romain Toro, Osvaldo Del Pozo-Zamudio +8
Non-classical light sources offer a myriad of possibilities in fundamental science and applications including quantum cryptography and quantum lithography. Single photons can encod…
Interfacing a quantum dot spin with a photonic circuit
Isaac J. Luxmoore, Nicholas A. Wasley, Andrew J. Ramsay +7
A scalable optical quantum information processor is likely to be a waveguide circuit with integrated sources, detectors, and either deterministic quantum-logic or quantum memory el…
Fast preparation of single hole spin in InAs/GaAs quantum dot in Voigt geometry magnetic field
T. M. Godden, J. H. Quilter, A. J. Ramsay +6
The preparation of a coherent heavy-hole spin via ionization of a spin-polarized electron-hole pair in an InAs/GaAs quantum dot in a Voigt geometry magnetic field is investigated.…
Charge control in InP/GaInP single quantum dots embedded in Schottky diodes
O. D. D. Couto, J. Puebla, E. A. Chekhovich +6
We demonstrate control by applied electric field of the charge states in single self-assembled InP quantum dots placed in GaInP Schottky structures grown by metalorganic vapor phas…
Coherent optical control of the spin of a single hole in a quantum dot
T. M. Godden, J. H. Quilter, A. J. Ramsay +7
We demonstrate coherent optical control of a single hole spin confined to an InAs/GaAs quantum dot. A superposition of hole spin states is created by fast (10-100 ps) dissociation…
