Closing in on 'holy grail' of room temperature quantum computing chips

To process information, photons must interact. However, these tiny packets of light want nothing to do with each other, each passing by without altering the other. Now, researchers have coaxed photons into interacting with one another with unprecedented efficiency — a key advance toward realizing long-awaited quantum optics technologies for computing, communication and remote sensing.

Scientists create fully electronic 2-dimensional spin transistors

Physicists have constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) was placed on top of graphene to induce charge-to-spin conversion in the graphene.

New method for detecting quantum states of electrons

Researchers have devised a new method — called image charge detection — to detect electrons' transitions to quantum states. Electrons can serve as quantum bits, the smallest unit of quantum information; these bits are foundational to larger computational systems. Quantum computers may be used to understand the mechanism of superconductivity, cryptography, artificial intelligence, among other applications.
