The second is still somewhere on the horizon but getting closer, according to an Oak Ridge National Laboratory quantum physicist.<\/p>\n<p>\u201cI\u2019m a quantum physicist, so that\u2019s my job, and when I heard there\u2019s \u2018a second quantum revolution,\u2019 I wondered what was the first. Well, the first one was when we pretty much worked out quantum mechanics around the turn of the century. The second will be when we actually use quantum mechanics to do useful things,\u201d said Dr. Raphael Pooser, \u201clike computing or sensing or networking.\u201d<\/p>\n<p>Pooser\u2019s talk, hosted by the University of Tennessee at Chattanooga at its Center for Professional Education on Monday, April 17, is the first of three on campus this week. The presentations are part of \u201cGig City Goes Quantum,\u201d an initiative to prepare for education, jobs and business opportunities in the emerging quantum technology field.<\/p>\n<p>UTC is a substantial collaborator in the initiative being led by EPB and Qubitekk, which are partnering to offer the&nbsp;<strong><a href=\"https:\/\/quantum.epb.com\/\">EPB Quantum NetworkSM&nbsp;powered by Qubitekk<\/a><\/strong>. The nation\u2019s first industry-led, commercially available quantum network, it is expected to be operational by summer\u2014and UTC will be home to a node of the network.<\/p>\n<p>Pooser\u2019s presentation is among a series of educational and informational activities that kicked off on World Quantum Day (April 14) and continue through May 31.<\/p>\n<p>He began with a brief history of ORNL\u2019s involvement in the Manhattan Project\u2014developing the world\u2019s first atomic bombs around the time of the second world war\u2014and the lab\u2019s evolution to its current global pre-eminence in supercomputing. The \u201csuper\u201d in that kind of computing refers to super-fast, super-high capacity.<\/p>\n<p>\u201cIt\u2019s state-of-the-art for classical computing today,\u201d Pooser said, \u201cand they\u2019re doing AI (artificial intelligence) on it. They\u2019re doing climate models on it. There\u2019s a lot of biological computations, protein-folding and that kind of thing. Just anything you can think of when it comes to answering basic science questions.\u201d<\/p>\n<p>Meanwhile, Pooser said, he and some colleagues have wondered what\u2019s next once such \u201cclassical\u201d supercomputing reaches its upper limits of speed and capacity.<\/p>\n<p>\u201cWhat\u2019s the next thing if you can\u2019t scale these machines anymore? At some point, energy use is out of control with classical computing and we will hit a wall,\u201d Pooser said. Quantum computing and the quantum physics on which it is based promise to overcome some of the limits of classical computing.<\/p>\n<p>\u201cThere are just some scientific questions that classical computers cannot answer, unfortunately. It\u2019s not that they can\u2019t answer them\u2014in principle, they can, but to answer some questions would take those machines and all the energy on the earth dedicated to running these machines, running for still longer than the universe has been around,\u201d Pooser said, \u201cso we\u2019re designing these other machines that can answer those questions a little bit faster.<\/p>\n<p>\u201cNot every question. You can\u2019t make a quantum computer do everything a classical computer does faster, just some things faster.\u201d<\/p>\n<p>Among capabilities quantum computing offers that classical computing cannot: simulation of other quantum systems; \u201cfactoring large numbers\u201d (code breaking); sampling from large probability distributions; and analyzing \u201coptimization problems.\u201d<\/p>\n<p>What does all that mean to the everyday lives of people? Maybe solutions to problems of extraordinary scale and complexity, such as energy security, Pooser noted.<\/p>\n<p>He cited the fact that fertilizer production\u2014critical to meeting the world\u2019s food requirements\u2014 currently consumes about 5% of global natural gas and 2% of global energy production overall.<\/p>\n<p>\u201cThat\u2019s with 8 billion people in the world,\u201d Pooser said. \u201cWhat happens when we have 50 billion?\u201d<\/p>\n<p>To address that situation, \u201cQuantum computing will enable high-fidelity modeling\u201d of complex chemical reactions involved in fertilizer production\u2026using \u201cquantum algorithms\u201d exponentially faster than conventional approaches.<\/p>\n<p>Among other potential developments of quantum information science are ultrasensitive magnetometers and gravitometers, imaging with greatly reduced optical \u201cnoise\u201d and unbreakable encryption.<\/p>\n<p style=\"text-align: center\">*&nbsp;&nbsp; *&nbsp;&nbsp; *&nbsp;&nbsp; *&nbsp;&nbsp; *<\/p>\n<p>Next in the UTC-hosted three-part series of quantum presentations is Dr. James Troupe, chief scientist for quantum communications company Xairos, who will deliver a presentation on quantum networking on Wednesday, April 19.<\/p>\n<p>On Friday, April 21, quantum optics expert and UTC Assistant Professor of Physics Dr. Tian Li discusses quantum sensing.<\/p>\n<p>The presentations begin at noon in the UTC Center for Professional Education in the James R.
