Research headed by scientists at the University of Münster has led to the first quantum computing circuit that can fit on a chip. The single photon light source required for quantum computing typically requires stimulation by laser light. By replacing that with an electrically stimulated, carbon nanotube source, they were able to scale the component down and produce circuits also containing...

In the past few years, optical atomic clocks have made spectacular progress, becoming 100 times more precise than the best caesium clocks. So far, their precision has been available only locally, since frequency transfer via satellite cannot provide sufficient resolution. This has recently changed thanks to a new direct optical connection between France and Germany, established by joint work of...

A small team of researchers with affiliations to institutions in Italy, Japan and the U.S. has created a simulation that suggests that it should be possible for a single photon to simultaneously excite two atoms. In their paper published in the open access journal Physical Review Letters, the team describes the process leading to their simulation, what it showed and why they believe their...

A blood disorder called thrombocytopenia can cause uncontrollable bleeding in sufferers, thanks to a shortage of platelets - the blood cells that are involved in the job of clotting in damaged vessels. Treatment for the condition has to date centered either on drugs or transfusions of fresh platelets to restore the balance, with accompanying risks of infection or other surgical complications. A...

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied concepts of classical holography to the world of quantum phenomena. A new measurement technique has enabled them to register the first-ever hologram of a single light particle,...

The US Food and Drug Administration (FDA) has approved the Raindrop Near Vision Inlay, a device implanted into the cornea using a femtosecond laser to improve near vision in patients with presbyopia. It is the first FDA-approved implantable corneal device that changes the shape of the cornea to achieve improved vision.

The human body is controlled by electrical impulses in the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various diseases, for example diseases of the brain or heart problems in young fetuses. Researchers from the Niels Bohr Institute have now succeeded in developing a method for extremely precise measurements of...

A new MIT study could open up new areas of technology based on types of light emission that had been thought to be "forbidden" or at least so unlikely as to be practically unattainable. The new approach, the researchers say, could cause certain kinds of interactions between light and matter, which would normally take billions of years to happen, to take place instead within billionths of a second...
