Nano Letters
A compact, efficient single photon source that operates at ambient temperatures on a chip
Hebrew University of Jerusalem scientists demonstrated a compact, efficient single photon source that can operate on a chip at ambient temperatures. A highly directional single photon source could lead to compact, cheap, and efficient sources of quantum information bits for future quantum technological applications. The team is working on a new generation of devices to allow production of single photons straight from the chip into optical fibers, without any additional optical components.

An experiment seeks to make quantum physics visible to the naked eye
Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by a team around a theoretical physicist at the University of Basel. The experiment might pave the way for new applications in quantum physics.

Nuclear pores captured on film
Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed 'living' nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular 'tentacles' inside the pore.

Cooling graphene-based film close to pilot-scale production
Heat dissipation in electronics and optoelectronics is a severe bottleneck in the further development of systems in these fields. To come to grips with this serious issue, researchers at Chalmers University of Technology have developed an efficient way of cooling electronics by using functionalized graphene nanoflakes. The results will be published in the renowned journal Nature Communications.

University of Illinois researchers create 1-step graphene patterning method
Researchers from the University of Illinois at Urbana-Champaign have developed a one-step, facile method to pattern graphene by using stencil mask and oxygen plasma reactive-ion etching, and subsequent polymer-free direct transfer to flexible substrates. This approach demonstrates a new possibility to overcome limitations imposed by existing post-synthesis processes to achieve graphene micro-patterning and sets forth transformative changes in 'do It yourself' graphene-based device development for broad applications including flexible circuits/devices and wearable electronics.

Researchers create a first frequency comb of time-bin entangled qubits
An international team of researchers has built a chip that generates multiple frequencies from a robust quantum system that produces time-bin entangled photons. In contrast to other quantum state realizations, entangled photons don't need bulky equipment to keep them in their quantum state, and they can transmit quantum information across long distances. The new device creates entangled photons that span the traditional telecommunications spectrum, making it appealing for multi-channel quantum communication and more powerful quantum computers.

Chemists use DNA to build the world's tiniest thermometer
Researchers at University of Montreal have created a programmable DNA thermometer that is 20,000x smaller than a human hair. One of the main advantages of using DNA to engineer molecular thermometers is that DNA chemistry is relatively simple and programmable. So, the research team has created various DNA structures that can fold and unfold at specifically defined temperatures.

Atomic magnets using hydrogen and graphene
CIC nanoGUNE researchers in collaboration with the Autonomous University of Madrid and the Institut Néel of Grenoble have shown for the first time that the simple absorption of a hydrogen atom on a layer of graphene magnetises a large region of this material. By selectively manipulating these hydrogen atoms, it is possible to produce magnetic graphene with atomic precision. The work has been published in the prestigious journal Science.
