(Phys.org)—Researchers have designed a new type of mirror that reflects light in a completely different way than conventional mirrors do. The new mirror, called a chiral meta-mirror, has potential applications for information ...
Rotating black holes and computers that use quantum-mechanical phenomena to process information are topics that have fascinated science lovers for decades, but even the most innovative thinkers rarely put them together. Now, ...
