Squeezing what hasn't been squeezed before Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider purchasing. For scientists, reducing uncertainty is a no less important goal, though in the weird realm of quantum physics, the term has a more specific meaning. For scientists working in quantum physics, the Heisenberg Uncertainty Principle says that...

Squeezed Laser Will Bring Gravitational Waves To The Light Of Day

  Measuring at the limits of the laws of nature — this is the challenge which researchers repeatedly take up in their search for gravitational waves. The interferometers they use here measure with such sensitivity that a particular quantum phenomenon of light — shot noise — limits the measuring accuracy. With the "squeezed light" method scientists from the Max Planck Society and the Leibniz University Hannover likewise use quantum physics in a countermove in order to...

Researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier. By significantly reducing the uncertainty in delicate measurements of microwave signals, the new amplifier could boost the speed and precision of quantum computing and communications systems. Conventional amplifiers add unwanted "noise," or random fluctuations, when they measure and boost...
