Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time.

Researchers reveal magnetic graphene supports quantum spin Hall states at zero field—paving the way for quantum spintronics.

Thousands of years ago, people made long and risky journeys across the sea—without modern boats, maps, or even metal tools. But how did they do it? A new study led by Professor Yousuke Kaifu ...
