Irrespective of possessing ideal single photon emitter properties, quantum emitters in 2-D hBN defect structures, exhibit constrained quantum light emission within the 300鈥 700 nm range. However, this emission range cannot fully satisfy the needs of an efficient quantum communication applications such ...
Quantum emitters in hBN A schematic of the hBN atomic lattice is shown in Fig. 1a, with blue and pink corresponding to nitrogen and boron atoms, respectively. The atomic structure of the quantum emitter(s) is still a matter of debate and a number of vacancy-related defects have been propos...
a PL variation as a function of the relative orientation between the emitter’s optical dipoles and an in-plane B = 890 G. b–d PL variation for magnetic fields parallel (b, β = 0°), perpendicular (c, β = 90°), and at 45° (d, β = 45°) to the ...
A second-order autocorrelation measurement on this emission site resulted in g2(0) = 0.19 seen in the inset. The hybrid single-photon light-emitting device shows the scalability of hBN quantum emitter in integrated applications. Additionally, the hybrid device could be integrated with optical ...
optimizing quantum emitter performance [30,37]. The determinacy of strained position [26,38], the flexibility of integration [27,39,40,41], and the versatile material library [42,43,44] render 2D TMDCs with unparalleled potential in quantum optical technologies compared to other material systems...
In the case of QC equipment the “photons” have to be modulated in some way to become “qbits”. The problem is that 99% of designs go about this the wrong way. They have the light emitter or detector as the first/last item in the line up respectivly, this is followed/preceaded...

Recently, much longer lifetimes (>200 ns) were reported in defects in chemical vapor deposition (CVD)-grown WSe2 that are encapsulated by hBN [25]. The PL intensity also exhibited saturation with increasing power, as expected for an atom-like emitter. The zero-phonon line (ZPL) consists of...
[147] argue about the superiority of their model based, on the argument that « the peak positions in the phonon sideband of the 4.1 eV emitter can be well-explained by the (quasi) localized phonon modes associated by the Stone–Wales defect, which should be a unique fingerprint and no ...
