Abstract: A non-classical light source emitting pairs of identical photons represents a versatile resource of interdisciplinary importance with applications in quantum optics and quantum biology. To date, photon twins have mostly been generated using parametric downconversion sources, relying on Poissonian number distributions, or atoms, exhibiting low emission rates. Here we propose and experimentally demonstrate the efficient, triggered generation of photon twins using the energy-degenerate biexciton–exciton radiative… Show more

“…The non-classical light source used in our experiments is represented by a deterministically fabricated quantum dot (QD) based SPS. This type of SPS was previously exploited to demonstrate the efficient generation of indistinguishable single photons [12], twin-photon states [13], and polarization entangled photon pairs [14]. The device is based on a single pre-selected InGaAs QD embedded precisely at the center of a monolithic microlens made out of GaAs.…”

“…However, in applications where active control is required, the ability to dynamically tune the linear and nonlinear optical properties of the individual QD at the nanoscale is essential. For instance, modifying the QD energy states through their confinement potential is a key ingredient in the generation of entangled photon pairs and for the creation of entanglement in QD–based quantum information processing . This flexibility is difficult to achieve in QDs grown using self‐assembled processes, such as molecular beam epitaxy (MBE) or chemical synthesis.…”
