Quantum Tech

Physicists at the Technical University of Munich, the Los Alamos National Laboratory and Stanford University (USA) have tracked down semiconductor nanostructure mechanisms that can result in the loss of stored information – and halted the amnesia using an external magnetic field. The new nanostructures comprise common semiconductor materials compatible with standard manufacturing processes.

Researchers from the Universities of Glasgow, Stanford, Tokyo and Würzburg are researching a new telecommunications technique which can harnesses quantum technology, potentially leading to a much more secure form of worldwide internet communications.

  Clearing the final hurdle to making silicon quantum computers a reality, a team of engineers from the University of New South Wales (UNSW), has built a quantum logic gate in silicon for the first time, making calculations between two qubits of information possible.

Hamamatsu Photonics is proud to announce that the peak Quantum Efficiency (QE) of the ORCA-Flash4.0 V2 has been increased to over 80% and it is now available for immediate delivery. With the ORCA-Flash4.0 V2 already delivering a wide field of view, wide dynamic range and fast frame rates, this increase in QE from the front-illuminated sensor makes it yet more versatile and powerful.

QD Vision has announced that Tongfang Global will soon provide its customers with 'wide colour gamut' televisions based on QD Vision’s Color IQ quantum dot technology. Color IQ solutions enable television and monitor manufacturers to deliver products capable of showing millions more colours than today’s 4K displays. Tongfang, which markets many of its products under the popular Seiki brand, will demonstrate its 55” 4K Ultra HD C...

MMD and QD Vision have joined forces to bring the world’s first quantum dot desktop monitor to Europe. The Philips 27” Full HD monitor (276E6ADS) delivers 99% Adobe RGB colour thanks to Color IQ technology from QD Vision. Philips monitors will showcase the quantum dot monitor at IFA, Hall 22 Booth 101. 

Advances at Oregon State University in manufacturing technology for quantum dots may soon lead to the next generation of LED lighting that produces a more user-friendly white light, while using fewer toxic materials and low-cost manufacturing processes that take advantage of simple microwave heating.

An exotic kind of magnetic behavior, driven by the mere proximity of two materials, has been analysed by a team of researchers at MIT and elsewhere, using a technique called spin-polarised neutron reflectometry. They say the finding could be used to probe a variety of exotic physical phenomena, and could ultimately be used to produce key components of future quantum computers.

The microprocessor inside a computer is a single multipurpose chip that has revolutionised people’s life, allowing them to use one machine to surf the web, check emails and keep track of finances. Now, researchers from the University of Bristol and Nippon Telegraph and Telephone (NTT), have pulled off the same feat for light in the quantum world by developing an optical chip that can process photons in an infinite number of ways.

Researchers have developed a method for growing ‘hybrid’ crystals at the nanoscale, in which quantum dots - essentially nanoscale semiconductors - of different materials can be sequentially incorporated into a host nanowire with perfect junctions between the components. An approach to self-assemble and tailor complex structures at the nanoscale opens opportunities to tailor properties and functionalities of materials for a wide r...
