We report experiments in which two photoluminescent samples of Strontium Aluminate pigments and Zinc Sulfide pebbles were quantum entangled via photoexcitation with entangled photons from a mercury lamp and a CRT screen. After photo-excitation, remote triggering of one of the sample with infrared (IR) photons yielded stimulated light variation from the quantum entangled other sample located 4 m away. The initial half-life of Strontium Aluminate is approximately one minute. However, molecules with a longer half-life may be found in the future. These experiments demonstrate that useful quantum information could be transferred through quantum channels via de-excitation of one sample of photoluminescent material quantum entangled with another.
