Leeds Quantum Cascade Terahertz Laser Sets New World Record in Output Power

A paper in the Institution of Engineering and Technology's (IET) journal Electronics Letters reports that the Leeds team has exceeded a 1 Watt output power from a quantum cascade terahertz laser.

Graphene Nanoribbons Act Like Quantum Dots

Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature – a property known as ballistic transport.

Optical Rogue Waves Observed in a Test Tube

Random processes in nature often underlie a so-called normal distribution that enables reliable estimation for the appearance of extreme statistical events. Meteorological systems are an exception to this rule, with extreme events appearing at a much higher rate than could be predicted from long-term observation at much lower magnitude.

Quantum Dots Enable Creation of Light with High Degree of Linear Polarization

By emitting photons from a quantum dot at the top of a micropyramid, researchers at Linköping University are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications.

Simple Way to Slow Down Polar Molecules Offers New Opportunities in Quantum Information Processing

Compared with our breath, passenger planes move at a pretty leisurely pace. On the average, nitrogen molecules, for example, travel at a speed of more than 1,700 kilometres per hour at room temperature, or almost one-and-a-half times the speed of sound. This means the particles are much too fast for many experiments, and also some conceivable applications.

Quantum Logic Spectroscopy Extended to Photon-Recoil Spectroscopy

Quantum logic spectroscopy – which is closely linked with the name of the 2012 Nobel prize laureate, David J. Wineland – has been significantly extended: this new method is called "photon-recoil spectroscopy" (PRS). The potential of this method has been demonstrated by the research group led by Piet Schmidt from the QUEST Institute, which is based at the Physikalisch-Technische Bundesanstalt, together with colleagues from Leibniz University Hannover.

New Ultra-Miniaturized Quantum Cascade Laser Products from Block Engineering

Block Engineering, the leader in Quantum Cascade Laser (QCL) instrumentation, announced today the release of two ultra-miniaturized QCL products, the Mini-QCL (TM) Module and the new LaserTune (TM) Infrared Source. The Mini-QCL is a widely-tunable QCL module for Original Equipment Manufacturers (OEMs), weighing only 75 grams (~2.5 oz). Block's next-generation LaserTune has been miniaturized to a compact (16.5 × 12.7 × 11 cm), wirelessly-controllable system, while offering the widest contiguous tuning range available on the market (greater than 1000 cm-1).

Quantum Biosystems Releases First Read Data Using Quantum Single Molecule Sequencing

Quantum Biosystems today announced the release of raw data access to its first reads. The company released reads showing an accuracy of more than 99% in non-homopolymer regions and homopolymer indels at a rate of ~10%. This release allows researchers to evaluate the platform and engage in its validation and development. It marks a major milestone in the single molecule electrical sequencing of DNA.
