Nader Khammassi

Researcher at the Quantum and Computer Engineering Lab of the Faculty of Engineering, Mathematics and Computer Science (EEMCS/EWI), Delft University of Technology.

Projects

Dr. Nader Khammassi joined the Quantum Computing Lab at the Delft University of Technology in the Netherlands in 2016. He is working at QuTech in collaboration with Intel to design a scalable quantum computer architecture based on superconducting qubit and spin qubit technologies.

Research

The initial topic of his research was focusing on high performance simulation of quantum computers. He developed a universal quantum computer simulator named QX, and started creating tools around QX to investigate the different layers of the quantum computer architecture being developed at QuTech. In 2016, the focus of his research was extended to the compilation of quantum algorithms through designing a new quantum programming framework called OpenQL. He contributed to the demonstration of the full architecture stack of a quantum computer from Software down to both the Hardware on both Superconducting qubits and Si-Spin qubit. Currently, his work is focusing on the design of a scalable micro-architecture and in extending its support to the Si-spin Qubits.
