We present a joint experiment-theory analysis of the temperature-dependent emission spectra, zero-phonon linewidth, and second-order correlation function light emitted from single organic molecule. observe spectra with line together several additional sharp peaks, broad phonon sidebands, strongly temperature dependent homogeneous broadening. Our model includes both localized vibrational modes molecule thermal bath, which we include nonperturbatively, is able to capture all observed features....
Commercially impactful quantum algorithms such as chemistry and Shor's algorithm require a number of qubits gates far beyond the capacity any existing processor. Distributed architectures, which scale horizontally by networking modules, provide route to commercial utility will eventually surpass capability single computing module. Such processors consume remote entanglement distributed between modules realize logic. Networked computers therefore rapidly distribute high fidelity modules. Here...
The indistinguishability of successively generated photons from a single quantum emitter is most commonly measured using two-photon interference at beam splitter. Whilst for sources excited in the pulsed regime bunching reflects full wave-packet emitted photons, continuous wave (cw) excitation, inevitable dependence on detector timing resolution and driving strength obscures underlying photon process. Here we derive method to extract cw measurements by considering relevant correlation...
Solid-state atomlike systems have great promise for linear optic quantum computing and communication but are burdened by phonon sidebands broadening due to surface charges. Nevertheless, coupling a small-mode-volume cavity would allow high rates of extraction from even highly dephased emitters. We consider the nitrogen-vacancy center in diamond, system understood poor optics interface with distinguishable photons, design silicon nitride that allows 99% efficient photons at 200 K an...
The silicon T center's narrow, telecommunications-band optical emission, long spin coherence, and direct photonic integration have spurred interest in this emitter as a spin-photon interface for distributed quantum computing networking. However, key parameters of the spin-selective transitions remain undetermined or ambiguous literature. In paper, we present Hamiltonian center TX state determine transition from ${\mathrm{T}}_{0}$ to ${\mathrm{TX}}_{0}$ combined analysis published results,...

Silicon nitride is an established platform for integrated photonics. Combining NV centres in nanodiamond, we indicate its capacity producing indistinguishable photons from highly dephased emitters and develop rapid characterisation techniques the resulting technology.
We use continuous-wave excitation of a single molecule to measure the full temporal wavepacket indistinguishability emitted photons, and show that light can determine coupling quantum emitters arbitrary nanophotonic structures.
