YPtBi is a known superconductor, but is it also a topological superconductor? A new experiment by researchers at the Chinese Academy of Sciences provides good evidence that it could be.

Quantum supremacy: China has successfully set up Jiuzhang 3.0, a quantum computer prototype that can perform Gaussian boson sampling 10^16 (10,000,000,000,000,000) times faster than the world's current fastest supercomputer Frontier.

Gaussian Boson Sampling with Pseudo-Photon-Number-Resolving Detectors and Quantum Computational Advantage

We report new Gaussian boson sampling experiments with pseudo-photon-number-resolving detection, which register up to 255 photon-click events. We consider partial photon distinguishability and develop a more complete model for the characterization of the noisy Gaussian boson sampling. In the...

176 qubits?

51 sounds like not a record-breaking number.

176 qubits?

I am not sure, I think a quantum computer is often describe as having so many qubits, each qubit would be in a coherent or superposition state. That is, each of them can be in 0 or 1 state simulatneously for a specific time which would enable computation on those states simulaneoudly. Entanglement is not the same thing, it involve more then one qubit that changes to one qubit would affect the other qubit that is use in specific way to further enhance the computation. So 176 qubits doesn't mean entanglement of all 176 qubits, maybe in many group of different no. of qubit?
