Research

My research interests are in quantum computing on near term noisy devices

Quantum Noise Characterization

Developing techniques for characterization, verification, and validation of the errors that occur in current quantum hardware.

Quantum Error Mitigation

Methods to supress and mitigate errors in hardware to improve the performance of current quantum hardware for near term applications.

Open Quantum Systems

Developing theoretical models for noise processes in superconducting systems, and the simulations of noise processes in open quantum systems.

Software

Qiskit Aer

Lead Developer

Qiskit Aer is a high-performance simulator framework for studying quantum computing algorithms and applications in the noisy intermediate scale quantum (NISQ) regime. It is written in C++ and Python and integrates with Qiskit-Terra. Some features of this library include:

Highly configurable noise models for simulating realistic device noise.
Automatic noise model generation based on device calibration information.
Multi-threaded paralellization through OpenMP

QuantumUtils

Lead developer

QuantumUtils for Mathematica is a Mathematica software library for symbolic and numerical simulations of quantum systems including and numerous tools useful for quantum information science. It was developed by Christopher Granade, Ian Hincks and myself during our PhDs. Some features of this library include:

Multi-partite tensor manipulations.
Quantum system modeling including qudits, circuits, spins, and cavities.
Symbolic Lie algebra simplification for spin and cavity systems.
Quantum channels in multiple representations.
Numerical and symbolic simulators for open and closed quantum system evolution.
An implementation of GRadient Ascent Pulse Engineering (GRAPE) including distortions.
Perturbative expansion tools such as the Magnus series, the Zassenhaus formula, and matrix power series
Visualization functions for displaying matrices, quantum states, data etc.
