SHENZHEN, China, Nov. 20, 2025 /PRNewswire/ -- MicroCloud Hologram Inc. (NASDAQ: HOLO), ("HOLO" or the "Company"), a technology service provider, innovatively proposed the "quantum degree" concept, ...

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But scientists at MIT and Harvard have just taken precision to an entirely new ...

At this year’s LASER World of Photonics (2025), in Munich, Germany, Toptica Photonics introduced to the market what the Munich-based company describes as “the first commercially available optical ...

In October 2024, researchers at the University of Science and Technology of China reached a new frontier in quantum physics: a Schrödinger-cat state with an unprecedented coherence time of 1,400 ...

There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...
