A research team from the University of Science and Technology of China (USTC) has developed a prototype superconducting quantum computer with 105 qubits and 182 connectors. The findings were published in Physical Review Journals.

According to the researchers, Zuchongzhi 3.0 is 1 quadrillion times (a number with 15 zeros) faster than the most powerful supercomputer and a million times faster than Google’s latest quantum computing results.

To test its capabilities, the USTC team performed a random quantum circuit sampling task using 83 qubits and 32 layers.

Key Specifications of Zuchongzhi 3.0:

Coherence time: 72 μs (longer coherence allows for more complex computations).
Single-qubit parallel operation accuracy: 99.90%.
Two-qubit operation accuracy: 99.62%.
Parallel readout accuracy: 99.13%.

For comparison, Google’s Willow quantum computer also has 105 qubits, but its coherence time is 68 μs.

The Chinese quantum system features a two-dimensional qubit architecture, enabling efficient connections between qubits and faster data transmission.

In February, Amazon introduced its first quantum computing chip, while Microsoft announced its Majorana 1 project.
