Quantum Computer Components 'Coalesce' to 'Converse'

If quantum computers are ever to be realized, they likely will be made of different types of parts that will need to share information with one another, just like the memory and logic circuits in today's computers do.

JQI Fellow and NIST Scientist Jacob Taylor Named PECASE Recipient

Three researchers at the National Institute of Standards and Technology (NIST) will receive the 2010 Presidential Early Career Awards for Scientists and Engineers (PECASE), the White House announced on Monday, Sept. 26, 2011. PECASE is the highest honor bestowed by the U.S. government on outstanding scientists and engineers beginning their independent research careers.

Hints of Universal Behavior seen in Exotic 3-Atom States

A novel type of inter-particle binding predicted in 1970 and observed for the first time in 2006, is forming the basis for an intriguing kind of ultracold quantum chemistry. Chilled to nano-kelvin temperatures, cesium atoms---three at a time---come together to form a bound state hundreds or even thousands of times larger than individual atoms. Unlike the case of ordinary atoms, ...

PFC & JQI Summer Students

The Physics Frontier Center at JQI takes an active role in encouraging high-school students and college undergraduates to participate in various aspects of PFC research projects during the summer months. Each year many students gain invaluable, hands-on experience at laboratories and other research facilities at the University of Maryland (UMD) and the National Institute of Standards and Technology (NIST). They ...

Miniaturizing Delay Lines

Information traveling near the speed of light always sounds a little like science fiction. But this is what we get whenever we connect to the internet or watch cable television. Small packets of light called photons travel kilometers over networks of optical fiber, bringing information into our homes.

If fiber optic cable is ideal for carrying information, why haven’t photons ...

Understanding Quantum Magnetism, Atom by Atom

Joint Quantum Institute (JQI) researchers led by Christopher Monroe, with theoreticians from University of Michigan, University of Auckland, and Georgetown University have observed a quantum ferromagnet using a nine ion crystal, in an atom-by-atom approach to quantum simulations of magnetism. These new results appear in the July 5, 2011 issue of Nature Communications in a paper entitled "Onset ...

The First Non-Trivial Atom Circuit

Researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland (UM) have created the first nontrivial "atom circuit," a donut-shaped loop of ultracold gas atoms circulating in a current analogous to a ring of electrons in a superconducting wire.

The researchers create a synthetic electric field (E*) in an ultracold gas of several hundred thousand rubidium atoms (BEC) immersed in a constant magnetic field (B0). Using lasers (red arrows), the team alters the atoms’ energy-momentum relationship, which causes the atoms to move in a way that is physically identical—and mathematically equivalent—to how a charged particle would move in an electric field. credit: NIST

Neutral Atoms Made to Act Like Electrically Charged Particles

Completing the story they started by creating synthetic magnetic fields, scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields.
