Today, someone with breast cancer may undergo several rounds of chemotherapy and spend months in limbo before medical scans can show if that particular cocktail of toxic drugs is shrinking the tumor. (more…)
IBM scientists will focus on building the first logical quantum bit
Yorktown Heights, N.Y. – 08 Dec 2015: IBM announced today that the U.S. Intelligence Advanced Research Projects Activity (IARPA) program has notified IBM that it will award its scientists a major multi-year research grant to advance the building blocks for a universal quantum computer. (more…)
A common blue pigment used in the £5 note could have an important role to play in the development of a quantum computer, according to a paper published in the journal Nature. (more…)
Berkeley Lab researchers and their colleagues extend electron spin in diamond for incredibly tiny magnetic detectors
From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs – and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes.
Now scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, working with colleagues from Harvard University, have improved the performance of one of the most potent possible sensors of magnetic fields on the nanoscale – a diamond defect no bigger than a pair of atoms, called a nitrogen vacancy (NV) center.

Researchers at NASA’s Jet Propulsion Laboratory and the California Institute of Technology, both in Pasadena, have developed a new type of amplifier for boosting electrical signals. The device can be used for everything from studying stars, galaxies and black holes to exploring the quantum world and developing quantum computers.
“This amplifier will redefine what it is possible to measure,” said Jonas Zmuidzinas, chief technologist at JPL, who is Caltech’s Merle Kingsley Professor of Physics and a member of the research team. (more…)
