A Copenhagen team has unlocked a clever “backdoor” into studying rare quantum states once thought beyond reach.
Scientists at the Niels Bohr Institute, University of Copenhagen, have discovered a new approach for investigating rare quantum states that occur within superconducting vortices. These states were first proposed in the 1960s, but confirming their existence has proven extremely challenging because they occur at energy levels too small for most experiments to detect directly.
This breakthrough was achieved through a mix of creative problem-solving and the advanced development of custom-made materials in the Niels Bohr Institute’s laboratories. The research findings have been published in Physical Review Letters.
