Sweden’s Chalmers University Simplifies Process of Measuring the Temperatures of Quantum Computers

(ComputerWeekly) Sweden’s Chalmers University of Technology has achieved a quantum computing efficiency breakthrough through a novel type of thermometer that is capable of simplifying and rapidly measuring temperatures during quantum calculations.
The novel thermometer is the latest innovation to emerge from the university’s research to develop an advanced quantum computer. The so-called OpenSuperQ project at Chalmers is coordinated with technology research organisation the Wallenberg Centre for Quantum Technology (WACQT), which is the OpenSuperQ project’s main technology partner.
WACQT has set the goal of building a quantum computer capable of performing precise calculations by 2030. The technical requirements behind this ambitious target are based on superconducting circuits and developing a quantum computer with at least 100 well-functioning qubits. To realise this ambition, the OpenSuperQ project will require a processor working temperature close to absolute zero, ideally as low as 10 millikelvin (-273.14° C).
Headquartered at Chalmers University’s research hub in Gothenburg, the OpenSuperQ project, launched in 2018, is intended to run until 2027. Working alongside the university in Gothenburg, WACQT is also operating support projects being run at the Royal Institute of Technology (Kungliga Tekniska Högskolan) in Stockholm and collaborating universities in Lund, Stockholm, Linköping and Gothenburg.
