Superconducting circuits could boost sensitivity of electron paramagnetic resonance
Electron paramagnetic resonance (EPR) is a powerful method for studying materials that have unpaired electrons. The method identifies and characterises paramagnetic species, usually by measuring microwave emission or absorption by their electron spins. As spins are weakly coupled to microwaves, the method can only be used for sufficiently large and concentrated samples. The EU-funded INDIGO project will borrow techniques from superconducting circuits to considerably increase EPR detection sensitivity, allowing to image new types of micro-sized samples. INDIGO will offer great promise for biology, chemistry and condensed matter physics, for instance allowing to detect EPR signals in single cells, microprotein crystals or from organic semiconductors.
