In this month's issue of Physics World, Felicity Mellor, a senior lecturer in science communication at Imperial College London, questions whether the requirement of the modern physicist to collaborate and communicate is preventing the intellectual progress brought about by silence and solitude. Drawing on the approaches of Newton, Einstein, Cavendish and Dirac, Mellor highlights the recurring role that silence has played throughout the history of physics and asks if the "enforced...

Decay Used To Create Quantum Information
2013-11-25 09:47:26

University of Copenhagen - Niels Bohr Institute Usually, when researchers work with quantum information, they do everything they can to prevent the information from decaying. Now researchers at the Niels Bohr Institute, among others, have flipped things around and are exploiting the decay to create the so-called entanglement of atomic systems, which is the foundation for quantum information processing. The results are published in the scientific journal, Nature. "When working with...

Resonance In 'Artificial Atoms' Control Quantum Communication
2013-08-06 12:26:15

University of Copenhagen - Niels Bohr Institute Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters. In a conventional computer, information is made up of bits, comprised of 0's and 1's. In a quantum...

Researchers Develop Quantum Teleportation Between Gas Atoms
2013-06-06 15:31:14

Brett Smith for redOrbit.com - Your Universe Online Researchers from the Niels Bohr Institute have announced the capacity to consistently teleport information between two clouds of gas atoms, according to a report in the journal Nature Physics. "It is a very important step for quantum information research to have achieved such stable results that every attempt will succeed," said co-author Eugene Polzik, professor at the Niels Bohr Institute at the University of Copenhagen. In their...

Physicists Mimic Jupiter's Trojan Asteroids Inside Single Atom

[ Watch the Video ] Orbit of captured electron matches orbit of Jupiter's captured asteroids Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium. In a new paper published this week in Physical Review Letters, Rice's team and collaborators at the Oak Ridge National Laboratory and the Vienna University of...

Researchers at the Niels Bohr Institute have combined two worlds — quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new cooling method works quite paradoxically by heating the material! Using lasers, researchers...

Image 1 - New Record For Measurement Of Atomic Lifetime
2011-09-08 05:40:30

  Researchers at the Niels Bohr Institute have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks. The new measurements show a lifetime of 2050 seconds, which corresponds to approximately ½ hour. This is the longest lifetime ever measured in a laboratory. The results have been published in the scientific journal Physical Review Letters. The experiment...

Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems. Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a fraction of a second. But in new experiments at the Niels Bohr Institute researchers have succeeded in setting new records and...

Carl Friedrich Freiherr von Weizsäcker (June 28, 1912 "“ 28 April 2007) was German physicist and philosopher. He was the longest-living member of Werner Heisenberg's research team which investigated nuclear studies in Germany during World War II. Some argue whether he and the team willingly engaged in the development of a nuclear bomb for Germany, or if its failure was intentional because they did not want the Nazi regime to have nuclear weapons. Weizäcker was born in Kiel,...

Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist. He made essential contributions to understanding atom structure and quantum mechanics. Born in Copenhagen, Denmark to Christian Bohr and Ellen Adler, Bohr got his doctorate at Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his Bohr model about atom structure in 1913, introducing the theory of electrons...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
