In the race to develop superconducting quantum computers, superconducting quantum circuit technology has made remarkable progress.The technology has also been applied to quantum sensing, especially highly sensitive magnetometers.The target of on-chip measurement by superconducting quantum sensors has thus far been limited to impurities in semiconductors.However, the range of applications is not limited to such hard materials.This article describes the detection of ferric ions in neurons with a high-sensitivity, high-spatial-resolution magnetometer using a superconducting flux qubit.
