Nanotechnology Now - Press Release: Quantum steering for more precise measurements

Nanotechnology Now Einstein-Podolski-Rosen correlations can be used for precision measurements. (Image: Jurik Peter, Shutterstock) Abstract: Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles. Quantum steering for more precise measurements Basel, Switzerland | Posted on April 23rd, 2021 In quantum information, the fictitious agents Alice and Bob are often used to illustrate complex communication tasks. In one such process, Alice can use entangled quantum particles such as photons to transmit or teleport a quantum state - unknown even to herself - to Bob, something that is not feasible using traditional communications.

The First Life-Bearing Planet in Our Solar System? --Spectral Analysis of Molecules in Atmosphere of Venus May Confirm Its Presence

Recent research has revealed that Venus might have looked like Earth for three billion years, with vast oceans that could have been friendly to life leading to recent speculation that it may have been the first life-bearing planet. A conjecture spurred by the announcement in September of 2020 by an international group of researchers reported in the journal Nature Astronomy, that there may be a whiff of life in the famously inhospitable planet’s atmosphere in the form of traces of phosphine, a gas that is associated with life where there is no oxygen. Plenty of time for evolution to kick in

A billion years from now, a lack of oxygen will wipe out life on Earth

Earth will not be able to support and sustain life forever. Our oxygen-rich atmosphere may only last another billion years, according to a new study in Nature Geoscience. As our Sun ages, it is becoming more luminous, meaning that in the future Earth will receive more solar energy. This increased energy will affect the surface of the planet, speeding up the weathering of silicate rocks such as basalt and granite. When these rocks weather the greenhouse gas carbon dioxide is pulled out of the atmosphere and through chemical reactions locked in carbonate minerals. In theory, the Earth should start to cool down as carbon dioxide levels fall, but in around 2 billion years this effect will be negated by the ever-harshening glare of the Sun.
