When light shines on certain materials, it causes them to emit electrons. This is called “photoemission” and it was discovered by Albert Einstein in 1905, winning him the Nobel Prize. But only in the last few years, with advancements in laser technology, have scientists been able to approach the incredibly short timescales of photoemission. Researchers at EPFL have now determined a delay of one billionth of one billionth of a second in photoemission by measuring the spin of photoemitted electrons without the need of ultrashort laser pulses. The discovery is published in Physical Review Letters.

Photoemission

Photoemission has proven to be an important phenomenon, forming a platform for cutting-edge spectroscopy techniques that allow scientists to study the properties of electrons in a solid. One such property is spin, an intrinsic quantum property of particles that makes them look like as if they were rotating around their axis. The degree to which this axis is aligned towards a particular direction is referred to as spin polarization, which is what gives some materials, like iron, magnetic properties.

Our story on QC just keeps advancing as I cannot wait to see this technology on our smart devices.

Holographic atomic memory, invented and constructed by physicists from the Faculty of Physics at the University of Warsaw, is the first device able to generate single photons on demand in groups of several dozen or more. The device, successfully demonstrated in practice, overcomes one of the fundamental obstacles towards the construction of some type of quantum computer.

Completely secure, high-speed quantum communication, or even a model of quantum computer, may be among the possible applications for the new source of single photons recently built at the Faculty of Physics at the University of Warsaw (UW Physics), Poland. An unprecedented feature of this new device is that for the first time it enables the on-demand production of a precisely controlled group of photons, as opposed to just a single one.

Off to the races again; hope folks are onboard. Quantum Bio will grow in importance; and you were warned.

Microsoft today announced that they have open sourced Bio Model Analyzer, a cloud-based tool which allows for biologists to model cell interaction and communication. This latest move is one of the many Microsoft Research initiatives which aims to help lab experts use computer science to speed up breakthroughs in cancer research and treatment.

According to the post, the Bio Model Analzyer (BMA) allows for researchers and science to compare the normal processes of healthy cells to the abnormal processes that occur when disease infects the body. Set against more traditional methods, when using computers, researchers can quickly explore many more possibilities than were previously possible. Jasmin Fisher, a Senior researcher in the programming principles and tools group in Microsoft’s Cambridge, U.K explains in the post:

As Geordie Rose was to QC; Jim Al-Khalili is to Quantum Biology. QC and QB will together make a new advance quantum tech world complete as both are needed to advance both the foundation(infrastructure) and the products and services we love and rely on.

What is quantum biology? Philip Ball explains how strange quantum effects take place in the messy world of biology, and how these are behind familiar biological phenomena such as smell, enzymes and bird’s migration.

Bohr’s atomic model was utterly revolutionary when it was presented in 1913 but, although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a much wider-ranging and less known quantum theory, the principles of which changed over time. Researchers at the University of Barcelona have now analysed the development in the Danish physicist’s thought — a real example of how scientific theories are shaped.

Most schools still teach the atomic model, in which electrons orbit around the nucleus like the planets do around the sun. The model was proposed more than a century ago by Danish physicist Niels Bohr based on Rutherford’s first model, the principles of classical mechanics and emerging ideas about ‘quantisation’ (equations to apply initial quantum hypotheses to classical physical systems) advanced by Max Planck and Albert Einstein.

As Blai Pié i Valls, a physicist at the University of Barcelona, explains: “Bohr published his model in 1913 and, although it was revolutionary, it was a proposal that did little to explain highly varied experimental results, so between 1918 and 1923 he established a much more wide-ranging, well-informed theory which incorporated his previous model.”

Unknown physics that could undermine quantum theory has been ruled out in a measurement guided by starlight emitted at least six centuries ago.

Surprised it took this long for this article to surface.

A purely organic p–n junction is used as the luminescent center in a novel planar device that exhibits a high external quantum efficiency and an extremely low driving voltage.

In recent years, organic LEDs (OLEDs) have become a popular option for creating digital displays. These devices generally consist of three types of semiconductors (i.e., a p-type hole-transport layer, an n-type electron-transport layer, and an emission layer).^1–3 The emission layer (normally capable of bipolar transport) provides a platform for carrier capture, exciton generation, and transition, and the luminescent property of an OLED mainly depends on the fluorescence behavior of single-molecule emitters. However, the incorporation of the emission layer within the structure of an OLED causes two energy barriers to be induced at the interfaces with the emission and transport layers. This means that the driving voltages for OLEDs are generally much larger than for traditional inorganic LEDs (with similarly chromatic emission). Moreover, the excitons that are generated at most purely organic emitters have a strong binding energy.
