Material could bring optical communication onto silicon chips

Ultrathin films of a semiconductor that emits and detects light can be stacked on top of silicon wafers, researchers report in a study that could help bring optical communication onto silicon chips.

Ultracold molecules hold promise for quantum computing

A study by MIT researchers shows that collections of ultracold molecules can retain the information stored in them for hundreds of times longer than previously achieved in these materials. These clusters might thus serve as “qubits,” the basic building blocks of quantum computers.

Majorana fermions predicted in a superconducting material

MIT physicists propose that a class of superconducting materials can host Majorana fermions near absolute zero, and that their existence can be verified using nuclear magnetic resonance.
