My research has concentrated
on quantum computation, particularly quantum fault tolerance and quantum
error correction. However, my technical interests include the broader
fields of data mining, intrusion detection, and classical fault tolerance.
In my research, I have developed a fault-tolerant software architecture
for quantum computers that maps a high-level program into fault-tolerant
machine-level instructions, along with methods and tools to analyze
and simulate quantum circuits and determine component failure thresholds.
This work represents the first design flow for a quantum computer, and
includes the development of a quantum assembly language, QASM, and a
suite of tools for its compilation and simulation. In addition, I have investigated
various nearest-neighbor quantum computer architectures and developed
several fault-tolerance threshold estimation techniques. Threshold estimation
is necessary for the engineering and realization of a reliable, scalable
quantum computer. Specifically, my research contributions are:

- A layered software
architecture for quantum computers. The design flow fault-tolerantly
maps a quantum algorithm written in a high-level language to technology-specific
instructions for a quantum computer or for use in a quantum simulator.

- A quantum assembly
language, QASM, and a toolsuite for its compilation and simulation. QASM
allows easy expression of quantum circuits, which with the toolsuite,
provides a platform for the evaluation and simulation of fault-tolerant
circuit components.

- A semi-analytical
analysis of fault-tolerance thresholds for a nearest-neighbor quantum
computer. Our fault-tolerance analysis is the first explicit model for
a nearest-neighbor architecture (an architecture which requires movement).
Our work also corrects previous inaccurate fault-tolerant threshold
estimation techniques.

- A new host-based
intrusion detection system for Windows registry anomaly detection. We
use one-class support vector machines (OCSVMs) to detect anomalous registry
behavior in the Windows registry.
