"Mass-Producible Miniature Quantum Memory Element Developed by Scientists"
Researchers at the University of Basel have developed a mass-producible quantum memory element based on rubidium atoms in a tiny glass cell, which can store and retrieve light pulses. This miniature quantum memory, only a few millimeters in size, could be mass-produced on a wafer and is crucial for the development of quantum networks and technologies, enabling tap-proof message transmission and connecting quantum computers. The researchers achieved this by heating the cell to increase vapor pressure and exposing the atoms to a strong magnetic field, allowing for the storage of photons for around 100 nanoseconds.
