Molecular Data Storage

Authors: George Rajna

From books to floppy disks to magnetic memory, technologies to store information continue to improve. Yet threats as simple as water and as complex as cyberattacks can still corrupt our records. [36] Researchers at Rensselaer Polytechnic Institute have come up with a way to manipulate tungsten diselenide (WSe2)-a promising two-dimensional material-to further unlock its potential to enable faster, more efficient computing, and even quantum information processing and storage. [35] The human brain has amazing capabilities making it in many ways more powerful than the world's most advanced computers. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25]
