LIGO discovers gravitational waves
We congratulate the LIGO team on their compelling detection of a gravitational wave signal produced by a pair of coalescing black holes. This represents a remarkable achievement, presenting not only the first detection of a gravitational wave, but also the first detection of a pair of merging black holes.
Dr. Danny Steeghs comments, "A century after Einstein's theory of General Relativity was presented, a long anticipated window on the Universe has now opened. These events also leave visible signatures that we will be chasing up with our new telescope, the Gravitational wave Optical Transient Observer ()."
Better off together: Improved quantum estimation of multiple parameters
Numerous scenarios in science and technology require the estimation of vectors such as electric, magnetic, gravitational or other force fields with extreme precision, the fundamental limits to which are set by quantum mechanics. In their latest paper, Tillmann Baumgratz and Animesh Datta show that quantum mechanics allows a more precise estimation of multiple parameters simultaneously rather than individually. The result provides a fundamentally better way estimating vector fields for a fixed amount of resources, and could be used in applications ranging from the study of quantum phase transitions to neuroimaging.
