New materials for quantum technologies

While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max ...

Laser light used to modulate free electrons into qubits

The laws of quantum physics are not only extraordinary—they also offer some far-reaching and unique possibilities for advanced information processing, quantum computing and cryptography. So far, the basic building blocks ...

Accessing high spins in an artificial atom

Scientists from SANKEN at Osaka University demonstrated the readout of spin-polarized multielectron states composed of three or four electrons on a semiconductor quantum dot. By making use of the spin filtering caused by ...

The secret of catalysts that increase fuel cell efficiency

Fuel cells, which are attracting attention as an eco-friendly energy source, obtain electricity and heat simultaneously through the reverse reaction of water electrolysis. Therefore, the catalyst that enhances the reaction ...

New physics rules tested on quantum computer

Aalto researchers have used an IBM quantum computer to explore an overlooked area of physics, and have challenged 100-year-old notions about information at the quantum level.
