Ultra Sensitive Detection Of Radio Waves Using Lasers
2014-03-05 14:30:33

University of Copenhagen - Niels Bohr Institute Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme...

A Feeling For The 'Light' Wave
2014-01-13 12:55:37

Max-Planck-Institute of Quantum Optics A team in the Laboratory for Attosecond Physics (LAP) at the Max-Planck-Institute of Quantum Optics has taken another step toward the achievement of complete control over the waveform of pulsed laser light. Together with colleagues based at LMU and the Technische Universität München (TUM), they have constructed a detector which provides a detailed picture of the waveforms of laser pulses that last for a few femtoseconds (1 fs = 10-15 seconds)....

The Center for Nano-Optics, a research center whose focus on the science of developing tools and instruments as small as 1,000 times thinner than a human hair could lead to major breakthroughs in technology and biomedicine, has been created at Georgia State University. Atlanta, GA (PRWEB) December 13, 2013 The Center for Nano-Optics, a research center whose focus on the science of developing tools and instruments as small as 1,000 times thinner than a human hair could lead to major...

Intense 2-color Double X-ray Laser Pulses Generated For First Time
2013-12-04 12:47:43

RIKEN A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are very powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions. SACLA is one of only two facilities in the world to...

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...

Physicists at the University of Basel have been successful in generating photons - the quantum particles of light – with only one color. This is useful for quantum information. The scientists have actively stabilized the wavelength of the photons emitted by a semiconductor thereby neutralizing the charge noise in the semiconductor. The results were developed in close collaboration with the Universities of Bochum, Paderborn and Lyon and have been published in the magazine Physical Review X....

Quantum Reality Is More Complex Than Previously Thought
2013-10-28 15:44:43

Faculty of Physics University of Warsaw Imagine you order a delivery of several glass vases in different colors. Each vase is sent as a separate parcel. What would you think of the courier if the parcels arrive apparently undamaged, yet when you open them, it turns out that all the red vases are intact and all the green ones are smashed to pieces? Physicists from the University of Warsaw and the Gdansk University of Technology have demonstrated that when quantum information is transmitted,...

A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...

Transfer Of Flying Quantum Bits At The Touch Of A Button
2013-08-15 10:40:22

Johannes Gutenberg Universitaet Mainz Hybrid technology makes possible highly reliable transmission of photonic qubits By means of the quantum-mechanical entanglement of spatially separated light fields, researchers in Tokyo and Mainz have managed to teleport photonic qubits with extreme reliability. This means that a decisive breakthrough has been achieved some 15 years after the first experiments in the field of optical teleportation. The success of the experiment conducted in Tokyo...

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, are always present. Always, that is, unless you can pull off a quantum trick. And that's just what a team led by researchers at the California Institute of Technology (Caltech) has done. The group has engineered a miniature silicon system...
