So which is it? 10 Billion (Hype?) or 100 Trillion (Hype!)
Two reports, same topic, same backstory, two very different headlines. So which is it? 10 Billion (Hype?) or 100 Trillion (Hype!) or both? (Hype? & Hype!) You decide. Because Quantum is Coming. Qubit China claims it built a quantum computer that’s 10 billion times faster than Google’s + State researchers in China recently developed a […]
China Claims Quantum Supremacy Albeit Solely Boson Sampling
The new light-based quantum computer Jiuzhang has achieved quantum supremacy Key points… + A photonic quantum computer, which harnesses particles of light, or photons, performed a calculation that’s impossible for a conventional computer, researchers in China report online December 3 in Science. That milestone, known as quantum supremacy, has been met only once before, in […]
U. of Science and Technology of China’s Photon Generator a New Standard in Quantum Technology?
Toward a Perfect Single-Photon Source Read More… + Optical-based quantum technologies use individual photons to encode and transmit information. However, even the best existing tools for generating photons produce beams whose number of photons fluctuates. This fluctuation creates uncertainty in the timing and intensity of a received signal. In the classical world, it was thought […]
