Milestone
First superconducting flux qubit observed in the QCT lab
January 12, 2022
Quantum Computing Technologies GroupThe QCT group at IFAE has observed the existence of the first superconducting flux qubit. This is a milestone for the group.These are the kind of chips that are of interest for quantum computing with quantum annealing, quantum optics and detection.
The chip was designed at IFAE and manufactured in Glasgow. The group will soon characterize its spectrum and lifetime.
The image on the right shows an unequivocal sign of the presence of the qubit. The horizontal line is the resonance of the resonator that is used to detect the qubit. Where things change show that the qubit and resonator have resonated, and their states are hybridized.
