Measurement technology continues to show its potential for quantum information Until recently measuring a 27-dimensional quantum state would have been a time-consuming, multistage process using a technique called quantum tomography, which is similar to creating a 3D image from many 2D ones. Researchers at the University of Rochester have been able to apply a recently developed, alternative method called direct measurement to do this in a single experiment with no post-processing. The work...

Study sets out to demystify a selected set of objections targeted against quantum theory in the literature A colloquium paper published in EPJ D looks into the alleged issues associated with quantum theory. Berthold-Georg Englert from the National University of Singapore reviews a selection of the potential problems of the theory. In particular, he discusses cases when mathematical tools are confused with the actual observed sub-atomic scale phenomena they are describing. Such tools are...

[ Watch the Video: Strange Behavior Of Bouncing Drops ] April Flowers for redOrbit.com - Your Universe Online It is possible to make a tiny droplet of fluid levitate on the surface of a vibrating bath, walking or bouncing across, according to a research team led by Yves Couder at the Université Paris Diderot. The droplets, propelled by their own wave fields, exhibit certain features previously thought to be exclusive to the microscopic quantum realm. This quantum-like behavior...

MIT researchers expand the range of quantum behaviors that can be replicated in fluidic systems, offering a new perspective on wave-particle duality In the early days of quantum physics, in an attempt to explain the wavelike behavior of quantum particles, the French physicist Louis de Broglie proposed what he called a "pilot wave" theory. According to de Broglie, moving particles — such as electrons, or the photons in a beam of light — are borne along on...

Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles. But a new paper by physics professor Andreas Albrecht and graduate student Dan Phillips at the University of California, Davis, makes the case that these quantum fluctuations actually are responsible for the probability of all actions, with far-reaching implications for theories...

Looking Beyond Space And Time To Cope With Quantum Theory

Centre for Quantum Technologies at the National University of Singapore Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behavior of the Universe. The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published today in Nature Physics. It is based on what the researchers call a 'hidden influence inequality'. This exposes how quantum predictions challenge our best...

In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly.Hardy's Paradox, the axiom that we cannot make inferences about past events that haven't been directly observed while also acknowledging...

In 2006, Andrew Jordan, professor of physics and astronomy at the University of Rochester, together with Alexander Korotkov at the University of California, Riverside, spelled out how to exploit a quantum quirk to accomplish a feat long thought impossible, and last week a research team at the University of California at Santa Barbara has tested the theory, proving it correct. Quantum particles behave in ways that from our everyday experience seem utterly impossible. For instance, quantum...

Word of the Day
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
