Two-qudit gate on a photonic platform achieves massive entangled quantum state. Researchers have built what could be a quantum version of a transistor – with qudits.

Quantum information processing promises to be much faster and more secure than what today’s supercomputers can achieve, but doesn’t exist yet because its building blocks, qubits, are notoriously unstable.

Purdue University researchers are among the first to build a gate – what could be a quantum version of a transistor, used in today’s computers for processing information – with qudits...

Researchers presented a new strategy for extending sodium ion batteries’ cyclability using copper sulfide as the material. This strategy has led to high-performance conversion reactions and is expected to advance the commercialization of sodium ion batteries as they emerge as an alternative to lithium ion batteries.

Professor Jong Min Yuk’s team confirmed the stable sodium storage mechanism using copper sulfide, a superior electrode material that is pulverization-tolerant and induces capacity recovery. Their findings suggest that when employing copper sulfide, sodium ion batteries will have a lifetime of more than five years with one charge per a day...

A team of researchers has developed tiny 10-gram robots that are inspired by ants: they can communicate with each other, assign roles among themselves and complete complex tasks together. These reconfigurable robots are simple in structure, yet they can jump and crawl to explore uneven surfaces. Individually, ants have only so much strength and intelligence. However, as a colony, they can use complex strategies to complete sophisticated tasks and evade larger predators.

At EPFL, robotics researchers in Professor Jamie Paik’s Laboratory have reproduced this phenomenon, developing tiny robots that display minimal physical intelligence on an individual level but t...

Team identifies dark trions as the next carrier of quantum information. Move aside, electrons; it’s time to make way for the trion. A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor – ultraclean single-layer tungsten diselenide (WSe2) – a feat that could increase the capacity and alter the form of information transmission.

In a semiconductor, such as WSe2, a trion is a quantum bound state of three charged particles. A negative trion contains two electrons and one hole; a positive trion contains two holes and one electron...
