"Google’s Willow Quantum Chip raises questions despite impressive claims"

Anhui Wentian Quantum Tech announced that its WT-QRNG300 random number chip has passed commercial cryptography testing and becoming the first quantum random number chip product in China to be certified.

very important for cryptographic tech security.

Chinese researchers claim that Zuchongzhi 3.0 rivals Google Willow. Specifically, it performed a computational task that would take the most advanced supercomputer over 6.4 billion years to complete.

• Chinese researchers write in a paper on arXiv that their Zuchongzhi 3.0 quantum computer performed a computational task that would take the Frontier supercomputer over 6.4 billion years to complete.
• The Zuchongzhi 3.0 system features 105 qubits with high fidelities and achieved one million samples from an 83-qubit random circuit in mere seconds, surpassing prior benchmarks set by Google’s Sycamore processor.
• While Zuchongzhi demonstrates quantum advantage through scale and speed, comparisons with Google’s Willow processor emphasize diverging research focuses, with Willow advancing fault tolerance critical for practical quantum applications.
