While it's a thrilling development, the inevitable rise of quantum computing means security teams are one step closer to facing a threat more formidable than anything before.

The team joins Google, which claimed it achieved quantum supremacy in Oct. 2019 using a "Supercold, superconducting metal," according to WIRED. IBM has also entered the quantum computing fray, while leveling criticism against Google's claims of supremacy.

Now, the Chinese researchers have claimed quantum supremacy using a quantum computation called Gaussian boson sampling, their paper explained, which uses particles of light sent through an optical circuit, measuring the output.

"First, China has invested heavily in funding quantum-computing research, and this new result shows that that investment is paying off. Second, it means two different approaches to building a quantum computer have now successfully achieved quantum supremacy. This could potentially speed up the arrival of commercially useful quantum computers, as one approach may succeed if and when the other runs into some technical roadblock."

Quantum Computing and RSA. John Prisco, from Safe Quantum Inc., said the ability for quantum computing to beat RSA is the goal, not the claims of quantum supremacy.
