October 9, 2023 | Sebastian A workshop was successfully held at the National Physical Laboratory, London, UK, on the topic of charge-phase duality in superconducting circuits. Several renowned speakers were invited and the workshop also saw a large number of contributing presentations, including several from the e-leaps consortium. During the two days of the workshop the approximately 50 attendees discussed the latest developments and state of art in the field of quantum phase slips for current metrology and understanding the duality between charge and phase in superconducting circuits.
