Quantum Physics


Multidimensional Optical Tech

Authors: George Rajna

A new design of optical chips enables light to experience multiple dimensions, which could underpin versatile platforms for advanced communications and ultra-fast artificial intelligence technologies. [39] Quantum computers, which use light particles (photons) instead of electrons to transmit and process data, hold the promise of a new era of research in which the time needed to realize lifesaving drugs and new technologies will be significantly shortened. [38] In the paper titled "Statistical Assertions for Validating Patterns and Finding Bugs in Quantum Programs," Huang and Margaret Martonosi, a professor of Computer Science at Princeton, identify three key difficulties in debugging quantum programs, and evaluate their solutions in addressing those difficulties. [37] Researchers at the University of Chicago published a novel technique for improving the reliability of quantum computers by accessing higher energy levels than traditionally considered. [36] An international team of researchers has taken an important step towards solving a difficult variation of this problem, using a statistical approach developed at the University of Freiburg. [35] Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds. [34] Electronics could work faster if they could read and write data at terahertz frequency, rather than at a few gigahertz. [33] A team of researchers led by the Department of Energy's Oak Ridge National Laboratory has demonstrated a new method for splitting light beams into their frequency modes. [32] Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution". [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information.
