Quantum ‘spookiness’ passes toughest test yet

Experiment plugs loopholes in previous demonstrations of 'action at a distance', against Einstein's objections — and could make data encryption safer.

It’s a bad day both for Albert Einstein and for hackers. The most rigorous test of quantum theory ever carried out has confirmed that the ‘spooky action at a distance’ that the German physicist famously hated — in which manipulating one object instantaneously seems to affect another, far away one — is an inherent part of the quantum world.

The experiment, performed in the Netherlands, could be the final nail in the coffin for models of the atomic world that are more intuitive than standard quantum mechanics, say some physicists. It could also enable quantum engineers to develop a new suite of ultrasecure cryptographic devices.

“From a fundamental point of view, this is truly history-making,” says Nicolas Gisin, a quantum physicist at the University of Geneva in Switzerland.

Nanoparticles are particles between 1 and 100 nanometers in size. In nanotechnology, a particle is defined as a small object that behaves as a whole unit with respect to its transport and properties.Particles are further classified according to diameter.[1] Ultrafine particles are the same as nanoparticles and between 1 and 100 nanometers in size, fine particles are sized between 100 and 2,500 nanometers, and coarse particles cover a range between 2,500 and 10,000 nanometers. Nanoparticle research is currently an area of intense scientific interest due to a wide variety of potential applications in biomedical, optical and electronic fields.[2][3][4][5] TheNational Nanotechnology Initiative has led to generous public funding for nanoparticle research in the United States.

Measuring Distances To Stars Just Got A Whole Lot Easier Thanks To This “Stellar Twin” Trick

Scientists have developed a novel method to calculate the distances to stars, and it could be useful in helping map the size of galaxies. The study is published in the Monthly Notices of the Royal Astronomical Society.

The researchers from the University of Cambridge examined what are known as “stellar twins.” These are stars that are identical, with exactly the same chemical composition, which can be worked out from their spectra – the type of light they emit. If they were both placed at the same distance from Earth, they would shine with equal brightness.

So the team realized that if the distance to just one of the stars was known, the other could be calculated relatively easily based on how brightly it was shining. The dimmer it is, the further away it is, and vice versa. The method can be used to accurately measure the distance.

“It’s a remarkably simple idea – so simple that it’s hard to believe no one thought of it before,” said lead author Dr Paula Jofre Pfeil, from Cambridge’s Institute of Astronomy, in a statement. “The further away a star is, the fainter it appears in the sky, and so if two stars have identical spectra, we can use the difference in brightness to calculate the distance.”

Youngster Galaxy Magnified by Abell 383

Hubble was first to spot this galaxy, one of the youngest in the distant universe. Its stars formed 13.5 billion years ago, a mere 200 million years after the Big Bang. The galaxy’s image is magnified by the gravity of a massive cluster of galaxies (Abell 383) parked in front of it, making it appear eleven times brighter. This phenomenon is called gravitational lensing.

Possible expansion/revision on QED theory needed? …

“Observations made with NIST’s Electron Beam Ion Trap indicate that, in ions with a strongly positive charge, electrons can behave in ways inconsistent with quantum electrodynamics (QED) theory, which describes electromagnetism. While more experiments are needed,the data could imply that some aspects of QED theory require revision. ”
