Quantum Computing has the potential to solve problems faster than classical supercomputers. This capability can change our world by enabling new methods to decrypt data, faster molecular analysis to design better drug treatments and solve complex optimization problems rapidly. The Quantum Computing and Optimization Lab (QCOL), at the Industrial and System Engineering Department of Lehigh University, was established in 2019 to accelerate the development of quantum computing optimization methodology. Mathematical optimization has critical applications in many disciplines, including physics, biology, engineering, economics, business, and finance. Quantum speed-up has the potential to lead to transformative, revolutionary advances and fundamentally impact society. The QCOL’s research focus is on developing novel QC methodologies to solve complex optimization problems.  Current research topics include

  • Quantum Interior Point Methods for solving Linear Optimization, Semi-definite Optimization, and Second-order Cone Optimization problems
  • Quantum methods to solve Combinatorial optimization problem such as Stable Set Problem in Graph theory
  • Quantum Errors and Their Models

QCO Lab is supported by a recently awarded $2,128,658 research grant from the Defense Advanced Research Projects Agency (DARPA). https://engineering.lehigh.edu/news/article/21m-darpa-grant-puts-ise-faculty-vanguard-quantum-computing

2023 Gene Golub SIAM Summer School on Quantum Computing and Optimization

QCOL is organizing G2S3 on Quantum Computing and Optimization at Lehigh University, Bethlehem, PA, from July 30 to August 12, 2023. In-person attendance is required. Graduate and advanced undergraduate students highly motivated to learn QC and optimization techniques are encouraged to apply. Experience in QC or optimization is not required to join the program.
