3-D Bose-Einstein Condensates Laser Cooling

Authors: George Rajna

Researchers at the MIT-Harvard Center for ultracold atoms and research laboratory of electronics have proposed a new method for producing 3-D Bose-Einstein condensates using laser cooling only. [43] Researchers have developed a new way of operating miniature quantum cascade lasers (QCLs) to rapidly measure the absorption spectra of different organic molecules in the air simultaneously. [42] Yale researchers have figured out how to catch and save Schrödinger's famous cat, the symbol of quantum superposition and unpredictability, by anticipating its jumps and acting in real time to save it from proverbial doom. [41] Multinational corporations, such as IBM and Google, are now building intermediate-size quantum computers with increasing number of quantum units or qubits. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers. [38] Calculations of a quantum system's behavior can spiral out of control when they involve more than a handful of particles. [37] Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. [36] The key technical novelty of this work is the creation of semantic embeddings out of structured event data. [35]
