Project Description

Electron Paramagnetic Resonance (EPR) spectroscopy is a powerful method for studying materials with unpaired electrons, including qubit materials. A qubit (short for “quantum bit”) is the basic unit of quantum information and the building block of quantum computers. Unlike a regular computer bit, which can only be 0 or 1, a qubit can exist in a mixture of both states at the same time, thanks to quantum mechanics.
The lifetime of a qubit tells us how long it can remain in this fragile quantum state before losing information. EPR helps scientists measure this lifetime (also called the spin–spin relaxation time) and understand the properties of qubits.
At the National MagLab, researchers use a state-of-the-art instrument called HiPER (High-Power Quasi-Optical W-band spectrometer). HiPER enables both continuous-wave and pulsed experiments, which provide much more detailed information about spin systems than traditional low-power EPR machines. This deeper understanding helps in developing better qubit materials, advancing the future of quantum information and computation.


Research Tasks: In this project, students will be introduced to the basics of qubit systems and get hands-on experience using high-field EPR and the HiPER instrument. The main goal is to learn how spin systems relax and how we can study that. Students will also practice doing literature reviews and giving short presentations to share what they have learned. The project includes several types of tasks, and assignments will be tailored to the student’s interests and motivation.

Skills that research assistant(s) may need: Students with backgrounds in Physics, Chemistry, Materials Science, or Quantum Science are encouraged to apply, but not mandatory. During the project, students will receive training in various aspects of experimental and data analysis work. Skills in Excel or MATLAB are desirable, but not required, as training will be provided. The project includes several types of tasks, and assignments will be tailored to the student’s interests and motivation.
