01 / Overview

In 2023, the superconducting quantum computing team of Shenzhen International Quantum Research Institute made breakthrough progress in distributed quantum computing research, achieving ultra-low loss and high fidelity quantum interconnection between distributed quantum computing chips, realizing the interconnection of five quantum chips, improving the fidelity of quantum state transmission between chips to the level of a single chip (99%), demonstrating a 12 bit maximum entangled state across three chips, and laying a solid foundation for large-scale and scalable distributed quantum computing networks. The relevant research results were published in the top international academic journal Nature Electronics on February 16, 2023.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

Superconducting quantum computing is the use of superconducting electronic circuits to achieve quantum computing. Superconducting quantum computing is developing rapidly, and the number of operable quantum bits is expected to expand to thousands or more in the coming years. However, superconducting quantum bits have a large size and require dedicated RF control circuits for each bit, making it increasingly difficult to integrate more bits on a single chip as the number of bits increases. The distributed quantum computing scheme, which constructs large-scale quantum processors by interconnecting multiple quantum chips, is expected to break through the dilemma of single-chip integration. In 2023, the superconducting quantum computing team of Shenzhen Institute of Quantum Science and Engineering made breakthrough progress in distributed quantum computing research, achieving ultra-low loss and high fidelity quantum interconnection between distributed quantum computing chips, realizing the interconnection of 5 quantum chips, improving the fidelity of quantum state transmission between chips to the level of a single chip (99%), and demonstrating the maximum 12 bit transmission across three chips.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
