Changing the color of quantum light on an integrated chip

Optical photons are ideal carriers of quantum information. But to work together in a quantum computer or network, they need to have the same color—or frequency—and bandwidth. Changing a photon's frequency requires altering ...

Nano-tuned solar cells

Solar cells that are more effective and cost less in production: Within the EU-project N2P (Nano to Product) researchers developed nano tuned surfaces to gain both.

Toward 'invisible electronics' and transparent displays

Researchers in California are reporting an advance toward the long-sought goal of "invisible electronics" and transparent displays, which can be highly desirable for heads-up displays, wind-shield displays, and electronic ...

Study reveals origin of superconductivity in nickelates

Nickelates are a material class that has excited scientists because of its recently discovered superconducting ability, and now a new study led by Cornell has changed where scientists thought this ability might originate, ...
