Quantum simulator characterises quantum systems
What happened right after the beginning of the universe? How can we understand the structure of quantum materials? How does the Higgs-Mechanism work? Such fundamental questions can only be answered using quantum field theories. These theories do not describe particles independently from each other; all particles are seen as a collective field, permeating the whole universe.
Solvents help quantum dots to shine bright
ROMIL solvents are helping researchers at the Cavendish Laboratory, the University of Cambridge’s Department of Physics, to develop novel quantum dots which could be used in the next generation of solar panels. James Xiao, a PhD student in the laboratory, explained: “We’re currently working on quantum dots which emit light in the infrared range, with the aim of significantly increasing the efficiency of photovoltaic cells.&rdquo...
Bringing quantum computing closer to reality
For 60 years computers have become smaller, faster and cheaper. But engineers are approaching the limits of how small they can make silicon transistors and how quickly they can push electricity through devices to create digital ones and zeros. That limitation is why Stanford electrical engineering Professor Jelena Vuckovic is looking to quantum computing, which is based on light rather than electricity.
Quantum Communication: how to avoid detrimental noise?
Scientists have been working intensely on developing methods for quantum information transfer. This would enable tap-proof data transfer or, one day, even the linking of quantum computers. Quantum information transfer requires reliable information transfer from one quantum system to the other, which is extremely difficult to achieve. Independently, two research teams – one at the University of Innsbruck and the other at TU Wien - have ...
Quantum physics offers insight into music expressivity
Scientists at Queen Mary University of London (QMUL) are bringing us closer to understanding the musical experience through a novel approach to analysing a common musical effect known as vibrato. Vibrato is the up-down oscillation in pitch introduced during instrumental or vocal performance, intended to add expressivity and to facilitate sound projection, and commonly used in opera.
Commercial quantum-computing service is a world first
IBM has announced its plans to begin offering the world's first commercial universal quantum-computing service—called IBM Q, the system will be made available to those who wish to use it for a fee sometime later this year. The system will build on IBM's Quantum Experience, a software development platform for programmers and developers interested in designing and building actual quantum-based applications.
Nano-trampoline probes quantum behaviour
A research group from Bar-Ilan University, in collaboration with French colleagues at CNRS Grenoble, has developed a unique experiment to detect quantum events in ultra-thin films. This novel research, to be published in the scientific journal Nature Communications, enhances the understanding of basic phenomena that occur in nano-sized systems close to absolute zero temperature.
NASA and MIT develop quantum-dot spectrometer
A NASA technologist has teamed with the inventor of a nanotechnology that could transform the way space scientists build spectrometers, the all-important device used by virtually all scientific disciplines to measure the properties of light emanating from astronomical objects, including Earth itself.
Will androids dream of quantum sheep?
Quantum replicants of responsive systems can be more efficient than classical models, say researchers from the Centre for Quantum Technologies in Singapore, because classical models have to store more past information than is necessary to simulate the future. They have published their findings in npj Quantum Information. The word 'replicant' evokes thoughts of a sci-fi world where society has replaced common creatures with artificial ma...
Quantum V BIA device aids body composition analysis
RJL Systems, a company based in Clinton Township, Michigan, launched last week the latest successor in their line of Bioelectrical Impedance Analysis (BIA) products, the Quantum V. The Michigan-based company, often considered the originators and chief innovators of BIA instrumentation for use in determining body composition, has regularly worked to advance their technology since the 1983 release of their initial FDA-cleared Class II medical devic...
