Research

I am interested in exciting problems within theoretical condensed matter and quantum information physics

Towards the goal of realizing commercial large scale quantum computers that operate at room temperature, I work on the optimization of quantum materials and quantum control protocols with this application in mind

On the quantum materials side, I use first-principles quantum mechanical approaches like density functional theory (DFT) to make predictions about structural, electronic, optical, magnetic, and vibrational properties. By screening many combinations we can suggest solid state defect/impurity configurations, molecules, and superconductors that hold promise for constructing qubits with long coherence times.

On the quantum control side, I am interested in Floquet engineering, quantum optimal control theory, and counterdiabatic driving to enable ultrafast property and state manipulation

Below is an image of a potential quantum computer consisting of an array of molecular spin qubits supported by an insulating single layer of hexagonal boron nitride. The state preparation, gate, state readout, and dynamical decoupling operations are enabled by the underlying electro-magneto-optical interconnect (in yellow).
