Quantum computers have been hailed for their revolutionary potential in everything from space exploration to cancer treatment, so it might not come as a surprise that Europe is betting big on the ultra-powerful machines.

A new €1 billion ($1.13 billion) project has been announced by the European Commission aimed at developing quantum technologies over the next 10 years and placing Europe at the forefront of “the second quantum revolution.”

The Quantum Flagship announced will be similar in size, time scale and ambition as the EC’s other ongoing Flagship projects: the Graphene Flagship and the Human Brain Project. As well as quantum computers, the initiative will aim to address other aspects of quantum technologies, including quantum secure communication, quantum sensing and quantum simulation.

A new method to create light while retaining the energy using Q-Dot technology.

All light sources work by absorbing energy – for example, from an electric current – and emit energy as light. But the energy can also be lost as heat and it is therefore important that the light sources emit the light as quickly as possible, before the energy is lost as heat. Superfast light sources can be used, for example, in laser lights, LED lights and in single-photon light sources for quantum technology. New research results from the Niels Bohr Institute show that light sources can be made much faster by using a principle that was predicted theoretically in 1954. The results are published in the scientific journal, Physical Review Letters.

Researchers at the Niels Bohr Institute are working with quantum dots, which are a kind of artificial atom that can be incorporated into optical chips. In a quantum dot, an electron can be excited (i.e. jump up), for example, by shining a light on it with a laser and the electron leaves a ‘hole’. The stronger the interaction between light and matter, the faster the electron decays back into the hole and the faster the light is emitted.

But the interaction between light and matter is naturally very weak and it makes the light sources very slow to emit light and this can reduce energy efficiency. Already in 1954, the physicist Robert Dicke predicted that the interaction between light and matter could be increased by having a number of atoms that ‘share’ the excited state in a quantum superposition.

A military-grade drone-killing ‘death ray’ that can reportedly destroy unmanned aerial vehicles (UAV) from up to 6 miles away could soon be in use in UK airports following a suspected collision with a passenger jet at Heathrow last Thursday.

The collision, which led to a drone ban over London during US President Barrack Obama’s UK visit, has forced authorities to consider more aggressive countermeasures.

It Looks exactly like Boston Dynamics cancelled Big Dog project, and it is armed with some kind of a Light machine gun. I said that cancelling the Big Dog project was a mistake. We Can’t Allow a robotics gap between the US and Russian/Chinese forces. And, the other side has absolutely no hang ups about arming their robots.

In his twitter page Igor Korotchenko, editor-in-chief of the Russian magazine Natsionalnaya Oborona (National Defense) has published the first-ever photos of Russia’s advanced biomorphic combat robot.

The alleged advanced biomorphic combat robot of Russia will move like a four legged animal and it will be equipped with a machine gun and guided antitank missiles, as suggested by the photos.

According to Sputnik, photos appeared after media reports said that Russia to create a state-of-the-art biomorphic combat robot which will walk on four “legs” and will be armed with a machine gun and guided antitank missiles.

Thin films of crystalline materials called perovskites provide a promising new way of making inexpensive and efficient solar cells. Now, an international team of researchers has shown a way of flipping a chemical switch that converts one type of perovskite into another—a type that has better thermal stability and is a better light absorber.

The study, by researchers from Brown University, the National Renewable Energy Laboratory (NREL) and the Chinese Academy of Sciences’ Qingdao Institute of Bioenergy and Bioprocess Technology published in the Journal of the American Chemical Society, could be one more step toward bringing to the mass market.

“We’ve demonstrated a new procedure for making solar cells that can be more stable at moderate temperatures than the perovskite solar cells that most people are making currently,” said Nitin Padture, professor in Brown’s School of Engineering, director of Brown’s Institute for Molecular and Nanoscale Innovation, and the senior co-author of the new paper. “The technique is simple and has the potential to be scaled up, which overcomes a real bottleneck in perovskite research at the moment.”
