Qubit chip keeps its performance after a trip from Sweden to Singapore and back

[Gadget49]

Can a superconducting quantum chip survive being shipped around the world? Chalmers Next Labs, ConScience and Singapore's National Quantum Federated Foundry set out to find out, and Quantum Computing Report says the answer looks like yes. The chip kept its key performance figures after travelling from Gothenburg to Singapore and back

The test used ConScience's five qubit QiB1 chip, as part of a twin testbed project funded by Sweden's innovation agency Vinnova. The team measured a baseline in Gothenburg in January 2026, with coherence times above 100 microseconds. The chip was then shipped to Singapore for 80 hours of automated testing

In Singapore, the control frequencies stayed within 1 percent of the Gothenburg values. The chip returned to Sweden in August and was still within 1 percent of its baseline, with coherence times above 100 microseconds. That is a reassuring result for anyone hoping to build or buy chips internationally

The work follows an agreement signed in October 2025 between Singapore's National Quantum Office and Sweden's QSIP programme. The partners now plan to offer the twin testbed as a measurement service, and full data will be presented at the APS March Meeting in 2027

This kind of work is not glamorous, but it is essential for a real industry. Chips need to be made in one place and used in another without losing quality. Standardised testing across countries also helps customers trust what they are buying

How important is supply chain testing for quantum hardware? And could shared testbeds become standard in the industry?
