Excited State Spectroscopy of Boron Vacancy Defects in Hexagonal Boron Nitride using Time-Resolved Optically Detected Magnetic Resonance
Simon Baber, Ralph N. E. Malein, Prince Khatri +5
We report optically detected magnetic resonance (ODMR) measurements of an ensemble of spin-1 negatively charged boron vacancies in hexagonal boron nitride. The photoluminescence de…
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…
Frequency-encoded linear cluster states with coherent Raman photons
Dale Scerri, Ralph N. E. Malein, Brian D. Gerardot +1
Entangled multi-qubit states are an essential resource for quantum information and computation. Solid-state emitters can mediate interactions between subsequently emitted photons v…
Generating indistinguishable photons from a quantum dot in a noisy environment
Ted S. Santana, Yong Ma, Ralph N. E. Malein +3
Single photons from semiconductor quantum dots are promising resources for linear optical quantum computing, or, when coupled to spin states, quantum repeaters. To realize such sch…
Indistinguishable single photons with flexible electronic triggering
Adetunmise C. Dada, Ted S. Santana, Ralph N. E. Malein +6
A key ingredient for quantum photonic technologies is an on-demand source of indistinguishable single photons. State-of-the-art indistinguishable single-photon sources typically em…
Screening nuclear field fluctuations in quantum dots for indistinguishable photon generation
R. N. E. Malein, T. S. Santana, J. M. Zajac +6
A semiconductor quantum dot can generate highly coherent and indistinguishable single photons. However, intrinsic semiconductor dephasing mechanisms can reduce the visibility of tw…
Exciton fine-structure splitting of telecom wavelength single quantum dots: statistics and external strain tuning
Luca Sapienza, Ralph N. E. Malein, Christopher E. Kuklewicz +7
In a charge tunable device, we investigate the fine structure splitting of neutral excitons in single long-wavelength (1.1μm < λ< 1.3 μm) InGaAs quantum dots as a function of exter…
Electro-elastic tuning of single particles in individual self-assembled quantum dots
Chris E. Kuklewicz, Ralph N. E. Malein, Pierre M. Petroff +1
We investigate the effect of uniaxial stress on InGaAs quantum dots in a charge tunable device. Using Coulomb blockade and photoluminescence, we observe that significant tuning of…
