Story summary

Pennsylvania State University (Penn State) researchers have developed ultrathin strained films of barium titanate to advance quantum computing and improve energy efficiency in data centers.
The films improve electrical-to-optical signal conversion for long-distance quantum communication.
The team plans to explore this technique with other materials to achieve higher performance.
Separately, a study on time crystals suggests they may enhance quantum memory and sensing devices, signaling progress in integrating quantum technologies.

History

Historical Context

Richard Feynman proposed quantum computing in 1981, building on earlier developments in quantum mechanics and computer science. His insights addressed the limitations of classical computers in simulating quantum systems. Since then, organizations like IBM and Google have invested billions in quantum research, leading to advancements such as Penn State's ultrathin barium titanate films, which aim to enhance quantum communication and could revolutionize technology in the coming decades.
