Researchers at IIT Bombay have proposed a new test, dynamical fidelity susceptibility (DFS), to measure the 'quantumness' of gravity, suggesting that conventional entanglement-based tests may be insufficient.
Last year, the researchers had developed the world's best single photon source based on semiconductor quantum dots.
The team led by researchers from the University of Hawai'i (UH) at Manoa in the US discovered that these electrons in Earth's plasma sheet are contributing to weathering processes -- breaking down or dissolving of rocks and minerals -- on the Moon's surface.
XPoSat or X-ray Polarimeter Satellite is India's first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions.
An international team says that its ingenious experiment in which tiny parcels of light, or photons, are produced out of empty space has confirmed that a vacuum contains quantum fluctuations of energy, the Nature journal reported.
'Bottomline, hairline and waistline -- you have to watch them always.'
India is affected by a 'resource inefficiency curse'.
Thanga Meenkal is a heartwarming story told brilliantly with a simplicity and honesty that is seen so rarely in films these days.
'It is in electronics that the gap between where we are and where we need to be is most obvious and most persistent.' 'It is not only a national security issue, but also a commercial issue,' argues Rajeev Srinivasan.
'No PM has said no to anything we have proposed. I am not a politician and I cannot give speeches about things, but a lot of good things have been done in science by previous governments.' 'Under Dr Manmohan Singh, we could do a few important things. I used to meet him once in 6, 8 weeks. He often said, 'Professor Rao, you assume that you have my approval and carry on.' He was shy and decent. He is a real gentleman.' 'Science keeps me going at 80. I feel young.' Professor C N R Rao, the eminent scientist who was honoured with the Bharat Ratna, on the state of science in India.
