The software\nplatform is now used worldwide in public health research and response efforts. \n\n\u003C\/p\u003E\u003Cp\u003E\u201cDetermining the order of DNA bases for an entire genome has\nbecome relatively cheap and easy in recent years because of technological\nadvancements,\u201d said Jordan. \u201cThe hard part is figuring out what the genome\nsequence information means. Our software takes that next step. It analyzes the sequences,\nfinds the genes and provides clues as to which genes are involved in making\npeople sick. Manually, this process used to take weeks, months or a year. Now\nit takes us about 24 hours.\u201d \u003C\/p\u003E\u003Cp\u003EThe CG-pipeline software has been used to analyze last\nsummer\u2019s outbreak of \u0026nbsp;severe Escherichia coli\n(E. coli) infections that started in Germany and eventually led to illnesses in\n16 European countries, Canada and the United States. It was one of the largest E.\ncoli outbreaks in history, causing 50 deaths and 4,075 confirmed worldwide\ncases. The bacterium was traced to sprouts. Andrey Kislyuk, a graduate of the Bioinformatics\nPh.D. program who helped Jordan create the software, used the CG-pipeline while\nworking at Pacific Biosciences to understand why the strain of the bacteria\nthat caused the outbreak was so virulent. \u003C\/p\u003E\n\n\u003Cp\u003E\u201cThe software was used to determine that genetic material\nfrom two previously distinct strains of E. coli \u003Cem\u003E\u003Cem\u003E\u0026nbsp;\u003C\/em\u003E\u003C\/em\u003Ewas combined in a new, hyper-virulent strain,\u201d said Kislyuk. \u201cThe\nresulting hybrid strain seems to be more lethal than either of the parent\nstrains.\u201d \u003C\/p\u003E\u003Cp\u003EAnother Bioinformatics Ph.D. graduate who helped design and\nimplement the pipeline, Lee Katz, analyzed the bacteria that caused last year\u2019s\noutbreak of listeriosis in the United States while working at the CDC.\u0026nbsp; That outbreak was traced back to cantaloupes\nfrom a single farm in Colorado that were tainted with Listeria. Over the span\nof several months, there were 146 confirmed cases of listeriosis and 30 deaths,\nmaking it the deadliest outbreak of foodborne illness in the U.S. in 25 years.\nUsing the CG-pipeline, Katz was able to identify an important epidemiological genomic\nmarker, which will help track invasive strains of Listeria. \n\n\u003C\/p\u003E\u003Cp\u003EThe CG-pipeline software platform can be used to analyze any\nmicrobial genome sequence. It has already been applied to bacteria that cause a\nvariety of infectious diseases, including cholera, salmonella and bacterial\nmeningitis. \n\n\u003C\/p\u003E\u003Cp\u003EKatz continues to work closely with the Jordan lab to\nimprove the software.

Von Laue established the three basic principles of crystalline structure: order, periodicity and rotational symmetry. Shechtman then carefully defined each term, concluding with the universally accepted\u2014until Shechtman\u2019s discovery\u2014definition of crystals as \u201csolids composed of atoms arranged in a pattern that is periodic and in three dimensions,\u201d and that the rotational symmetry of crystals could be one-, two-, three-, four- or six-fold\u2014never five-fold and never more than six.\u003C\/p\u003E\u003Cp\u003EBut in 1982 as a young faculty member at the Technion, Shechtman one day discovered an apparent tenfold crystalline rotational symmetry in a crystal composed of aluminum and manganese, and further found that the crystal\u2019s structure was not periodic but quasi-periodic. To drive home his own surprise at the time, Shechtman displayed an image of the actual page from his 30-year-old notebook, with \u201c10fold!!!\u201d written clearly by a set of notations.\u003C\/p\u003E\u003Cp\u003E\u201cAt the end of the day, I knew this was something new and exciting,\u201d he said, further adding that years earlier in graduate school he\u2019d been given a test in which he had to prove that such rotational symmetry in crystals was impossible. \u201cAnd I did it.

First it was his group research leader at the U.S. National Bureau of Standards (now called the National Institute of Standards and Technology), who called Shechtman a \u201cdisgrace\u201d and kicked him out of the group. Then it was members of the International Union of Crystallography (IUCr), who rejected the study due to Shechtman\u2019s having used an electron microscope; the IUCr insisted that legitimate studies of crystalline diffraction used X-rays, not electron beams.\u003C\/p\u003E\u003Cp\u003EFinally it came down to one man: Linus Pauling, winner of Nobel Prizes in two different fields and one of the greatest scientists of the 20th century.

But many challenges must be addressed before these ultra-fast machines become available, among them, the loss of order in the systems \u2013 a problem known as quantum decoherence \u2013 which worsens as the number of bits in a quantum computer increases.\u003C\/p\u003E\u003Cp\u003EOne proposed solution is to divide the computing among multiple small quantum computers that would work together much as today\u2019s multi-core supercomputers team up to tackle big digital operations. The individual computers in such a system could communicate quantum information using Bose-Einstein condensates (BECs) \u2013 clouds of ultra-cold atoms that all exist in exactly the same quantum state. The approach could address the decoherence problem by reducing the number of bits necessary for a single computer.\u003C\/p\u003E\u003Cp\u003ENow, a team of physicists at the Georgia Institute of Technology has examined how this Bose-Einstein communication might work.

The research was funded by the U.S. Department of Energy (DOE) and the National Science Foundation (NSF). The work involved both an experimental physics group headed by Raman and a theoretical physics group headed by associate professor Carlos Sa De Melo, also in the Georgia Tech School of Physics.\u003C\/p\u003E\u003Cp\u003EThe researchers first assembled a gaseous Bose-Einstein condensate that consisted of as many as three million sodium atoms cooled to nearly absolute zero. To begin the experiment, they switched on a magnetic field applied to the BEC that instantly placed the system out of equilibrium. That triggered spin-exchange collisions as the atoms attempted to transition from one ground state to a new one. Atoms near one another became entangled, pairing up with one atom\u2019s spin pointing up, and the other\u2019s pointing down. This pairing of opposite spins created a correlation between pairs of atoms that moved through the entire BEC as it established a new equilibrium.\u003C\/p\u003E\u003Cp\u003EThe researchers, who included graduate student Anshuman Vinit and former postdoctoral fellow Eva Bookjans, measured the correlations as they spread through the cloud of cold atoms. At first, the quantum entanglement was concentrated in space, but over time, it spread outward like drop of dye diffuses through water.\u003C\/p\u003E\u003Cp\u003E\u201cYou can imagine having a drop of dye that is concentrated at one point in space,\u201d Raman said. \u201cThrough diffusion, the dye molecules move throughout the water, slowly spreading throughout the entire system.\u201d\u003C\/p\u003E\u003Cp\u003EThe research could help scientists anticipate the operating speed for a quantum computing system composed of many cores communicating through a BEC.\u003C\/p\u003E\u003Cp\u003E\u201cThis propagation takes place on the time scale of ten to a hundred milliseconds,\u201d Raman said. \u201cThis is the speed at which quantum information naturally flows through this kind of system. If you were to use this medium for quantum communication, that would be its natural time scale, and that would set the timing for other processes.\u201d\u003C\/p\u003E\u003Cp\u003EThough relevant to communication of quantum information, the process also showed how a large system undergoing a phase transition does so in localized patches that expand to attempt to incorporate the entire system.\u003C\/p\u003E\u003Cp\u003E\u201cAn extended system doesn\u2019t move from one phase to another in a uniform way,\u201d said Raman. \u201cIt does this locally. Things happen locally that are not connected to one another initially, so you see this inhomogeneity.\u201d\u003C\/p\u003E\u003Cp\u003EBeyond quantum computing, the results may also have implications for quantum sensing \u2013 and for the study of other physical systems that undergo phase transitions.\u003C\/p\u003E\u003Cp\u003E\u201cPhase transitions have universal properties,\u201d Raman noted. \u201cYou can take the phase transitions that happen in a variety of systems and find that they are described by the same physics. It is a unifying principle.\u201d\u003C\/p\u003E\u003Cp\u003ERaman hopes the work will lead to new ways of thinking about quantum computing, regardless of its immediate practical use.\u003C\/p\u003E\u003Cp\u003E\u201cOne paradigm of quantum computing is to build a linear chain of as many trapped ions as possible and to simultaneously engineer away as many challenges as possible,\u201d he said. \u201cBut perhaps what may be successful is to build these smaller quantum systems that can communicate with one another. It\u2019s important to try as many things as possible and to keep an open mind.
