Molecules with unpaired electron spins can act as qubits, the basic units of quantum information. Chemists can make them reproducibly and tune them precisely, which makes them promising for quantum sensing and computing.

What they work on
- Develop a finite-temperature density-matrix coupled-cluster method for spin ensembles and use it to study decoherence in interacting molecular qubit ensembles with varied dimensionality and disorder, and in periodically driven ensembles.
- Build an ab initio model of spin-spin and spin-vibrational interactions in molecular qubit ensembles to characterize decoherence, spin transport and cross-relaxation, the transfer of energy between spins.
- Create a spin-vibrational coupled-cluster method to simulate noisy, driven molecular qubit ensembles and test how stable entangled quantum states remain in dissipative molecular environments.
More about the research
Their fragile quantum states are disrupted, however, by surrounding nuclear spins and by molecular vibrations. This loss is called decoherence. This project develops theoretical and computational methods to simulate how large groups (ensembles) of molecular spin qubits behave over time, especially when they are out of equilibrium.
Why it matters
Molecular spin qubits could become building blocks for quantum sensors and quantum computers, but decoherence limits their use. Simulation tools that show which states resist noise, and how to create entangled states in real molecules, could help chemists design better qubit molecules and interpret experiments. They could also help connect molecular spins with other quantum platforms.
Known grants
