Letting light wander through milk—a surprising approach to better imaging
Light scattered in tissue usually ceases to be a useful source of information. But what if, instead of forcing it to travel along a single path, we allowed it to wander a little differently each time? Scientists from ICTER ...

Quantum computer boldly goes where no quantum computer has gone before: Space
There's big news from the quantum world. A quantum computer has been used in space for the first time. The device was aboard a spacecraft in low Earth orbit and demonstrated technology that could eventually help solve a problem ...
New model explains why glass becomes less transparent to terahertz light
Electromagnetic waves in the gigahertz (GHz) range, such as those used in mobile communications, can readily pass through many types of glass. However, transmission decreases significantly at terahertz frequencies above a ...

Light beam 'swims' upstream through a quantum fluid by violating Newton's third law
Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons ...
Scientists teleport quantum states across 100 parallel optical channels
Quantum communication networks consist of several connected nodes that exchange information encoded in quantum states. These networks could potentially enable more secure communications between quantum devices in different ...
X-ray light is like guitar music, with frequencies sliding continuously between harmonics
Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has developed a method that makes it ...

Photonic Legos of functional 3D thin-films unlock high-performance heterogeneous photonic integration
Photonic integrated circuits route information with optical signals instead of relying only on electrical currents. Silicon (Si) and silicon nitride (SiNx) are excellent photonic platforms for waveguides, but they cannot ...
Two-color light steers electrons through graphene's transient topological state
The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape ...
Stacked 2D materials reveal room-temperature multiferroicity and voltage-controlled magnetism
Multiferroics are materials that simultaneously exhibit two or more ferroic orders—stable arrangements of physical properties that can be switched using an external stimulus. These materials could be highly advantageous for ...
