Shenzhen SpinQ Technology Co. Ltd. has delivered samples of its superconducting quantum chip known as Shaowei to an unnamed research institute in the Middle East.

SpinQ, was founded in 2018 and claims to be the first Chinese company to have delivered superconducting quantum chips overseas.

Shaowei can perform single- and double-bit gate operations on the order of tens of nanoseconds, and can achieve more than 99.9 percent single-bit gate fidelity and more than 98 percent double-bit gate fidelity, the company said.

The company, also known as Shenzhen Liangxuan Technology Co. Ltd. and sometimes as Quspin, has previously released two portable quantum computers based on nuclear magnetic resonance, called the Gemini Mini Pro and the Triangulum Mini. These are desktop- and laptop-sized units, respectively (see SpinQ upgrades desktop quantum computing).

In-house manufacturing

SpinQ has invested in its own superconducting quantum chip production line in the Shenzhen-Hong Kong Innovation and Technology Cooperation Zone and has a ‘full-stack’ approach that includes quantum chips, measurement and control systems, software development and algorithm application platforms,

The decoherence time T1 of the “quantitative spin” of the Shaowei chip is of the order 10 to 100 microseconds. A longer T1 can ensure more gate operations and can also improve the upper bound on logic gate fidelity, the company said. In addition, “Shuixuan Shaowei” can perform single- and double-bit gate operations on the order of tens of nanoseconds, and can achieve more than 99.9% single-bit gate fidelity and more than 98% double-bit gate fidelity.

SpinQ said that during the delivery process for its superconducting quantum chips it provides technical support covering the design and manufacturing of its chips, low-temperature electronics, room temperature measurement and control systems, quantum bit measurement and control optimization.

“The successful delivery of superconducting quantum chips is not only a demonstration of our technical strength and innovation capabilities in the field of quantum computing, but also a demonstration of the global quantum computing industry,” said Jingen Xiang, founder and CEO of SpinQ, in a statement.
