Research Description

Nuclear magnetic resonance is a uniquely powerful tool, used in imaging, studies of protein structure, and fundamental science. However, nuclear magnetic resonance signals are notoriously weak, and most implementations must use expensive and bulky high-magnetic field superconducting magnets.

The goal of Alexander Sushkov’s research is to develop a nuclear magnetic resonance detection approach, with sensitivity limited by fundamental quantum spin projection noise. This focus on precision and control down to the quantum level is what makes this approach unique. For this work the group uses superconducting devices and circuits, as well as feedback and detection techniques developed in the field of quantum information science.

Research Impact

Dr. Sushkov’s research may enable nuclear magnetic resonance spectroscopy of microscopic samples, with no need for spin polarization in large magnetic fields and no need for excitation tipping pulses. This has potential broad impact on biochemical and life sciences, and medical diagnostics.

The impact on fundamental physics will be substantial, if the team can demonstrate that their detection and control techniques can significantly improve the sensitivity of magnetic resonance-based searches for ultralight axion dark matter.
