Accelerating neutral atoms on a table top

How do we accelerate neutral particles - i.e. particles that cannot be energized by electrical voltages? And do it over millimeters rather than hundreds of meters and moreover using lasers? Research at Ultra Short Pulse High Intensity Lab in TIFR has now found a novel scheme that can do precisely this.

New study explores the potential benefits and threats of nanotechnology research

Every day scientists learn more about how the world works at the smallest scales. While this knowledge has the potential to help others, it's possible that the same discoveries can also be used in ways that cause widespread harm. A new study born out of a Federal Bureau of Investigation workshop held at the University of Notre Dame in September 2012, tackles this complex 'dual-use' aspect of nanotechnology research.

DNA and quantum dots: All that glitters is not gold

A team of researchers at the National Institute of Standards and Technology has shown that by bringing gold nanoparticles close to the dots and using a DNA template to control the distances, the intensity of a quantum dot's fluorescence can be predictably increased or decreased. This breakthrough opens a potential path to using quantum dots as a component in better photodetectors, chemical sensors and nanoscale lasers.

Quantum communication: Each photon counts

Ultrafast, efficient, and reliable single-photon detectors are among the most sought-after components in photonics and quantum communication, which have not yet reached maturity for practical application. Researchers have now achieved the decisive breakthrough by integrating single-photon detectors with nanophotonic chips. The detector combines near-unity detection efficiency with high timing resolution and has a very low error rate.
