Jonas Bylander

Docent at Chalmers, Microtechnology and Nanoscience (MC2), Quantum Device Physics

Jonas Bylander has been on the faculty at Chalmers since 2013, teaching quantum optics, quantum information, and nanotechnology.Jonas is a principal investigator in WACQT – the Wallenberg Center for Quantum Technology. His team’s research is focused on building a quantum information processor with superconducting circuits. A quantum computer or quantum simulator can address certain computational problems that are intractable on a conventional supercomputer – a so-called “quantum advantage” or even “quantum supremacy.” Some application areas of such high-performance computing include optimization, machine learning, and quantum chemistry for biomolecules. The development of quantum hardware, control circuitry, and control methods for a quantum information processor constitute daunting challenges in physics as well as engineering. Keys to this research at Chalmers are the Nanofabrication Laboratory cleanroom at MC2 and the Quantum Technology measurement laboratory, equipped with several dilution refrigerators for cryogenic (10-mK) microwave and low-noise measurements.
