Quantum photonics technologies, like wavelength division multiplexing (WDM), for high-rate quantum key distribution require narrowband, spectrally tunable single photon emitters. Physical methods that rely on the application of large mechanical strain to epitaxial dots or electric and magnetic fields color centers in 2D metal dichalcogenides provide limited spectral tunability. Here we adopt a chemical approach synthesize family colloidal mixed-cation perovskite (Cs1–xFAxPbBr3) show highly...
In the search for materials quantum information science applications, colloidal semiconductor nanoplatelets (NPLs) have emerged as a highly promising class of due to their interesting optical properties, such narrow emission line widths and fast photoluminescence (PL) lifetimes at room temperature. So far, only few works focused on properties emission; however, NPLs, with atomic-scale thickness one-dimensional confinement, are candidates single-photon sources. Here, we demonstrate...
The interest in perovskite nanocrystals (NCs) such as CsPbBr3 for quantum applications is rapidly raising, it has been demonstrated that they can behave very efficient single photon emitters. main problem to tackle this context their photostability under optical excitation.

Achieving pure single-photon emission is essential for a range of quantum technologies, from computing to key distribution metrology. Among solid-state emitters, colloidal lead halide perovskite (LHP) nanocrystals (NCs) have attracted considerable interest due their structural and optical properties, which make them attractive candidates sources (SPSs). However, practical utilization has been hampered by environment-induced instabilities. In this study, we fabricate characterize in...
Perovskite nanophotonics is a rapidly emerging field that combines research in synthesis of materials with novel properties and photonics design strategies. Starting from early pioneering works on halide perovskite compounds showed great potential across optoelectronics applications, the ready to blossom by combining recent advances synthetic material design, development bottom-up or top-down nanostructuring approaches new concepts nanohophotonic engineering light matter interaction at...

Photons have been identified early on as a very good candidate for quantum technologies applications, carriers of information, either by polarization encoding, time encoding or spatial encoding. Quantum cryptography, communications, networks and computing are some the applications targeted so called photonics. Nevertheless, it was also clear at an stage that bulk optics handling states light would not be best option these technologies. More recently, single photons, entangled photons in...
