Ultrafast time-division demultiplexing of polarization-entangled photons [PDF]
Phys. Rev. Lett. 113, 163602 (2014), 2014 Maximizing the information transmission rate through quantum channels is essential for practical implementation of quantum communication. Time-division multiplexing is an approach for which the ultimate rate requires the ability to manipulate and detect single photons on ultrafast timescales while preserving their quantum correlations.

(3+1)D Printing of Core–Clad Waveguide by Two‐Photon Polymerization
Advanced Materials Technologies, EarlyView.Low‐loss, single‐mode core–clad optical waveguides are fabricated using a novel (3+1)D multiphoton polymerization technique in a hybrid resin. Precise laser power control and multi‐pass exposure enable refractive index engineering and reduce scattering. Raman spectroscopy confirms the correlation between polymerization and index change.

Generation and characterization of a source of wavelength division multiplexing quantum key distribution [PDF]
arXiv, 2004 Using spontaneous parametric down-conversion, photon pairs entangled in frequency and polarization were generated. After frequency resolving the photon pairs, the polarization correlations were measured on several polarization basis, and it was confirmed that the frequency resolved photon pairs were entangled in polarization, indicating the photon ...
