Welcome to the Laboratory for Quantum Information with Trapped Ions (QITI) of Prof. K. Rajibul Islam! We are a predominantly experimental research group at the Institute for Quantum Computing and the Department of Physics and Astronomy at University of Waterloo, Ontario, Canada.

Laser-cooled trapped ions are among the most pristine and controllable quantum systems. Research performed in Prof. Islam’s group is currently focused on the following:

  • Quantum simulation: The QITI laboratory is building a programmable trapped-ion quantum simulator with 171Yb+ qubits, with optical controls at the level of individual ions for studying problems in quantum many-body physics and computation.
  • QuantumION: In collaboration with Prof. Crystal Senko’s group and supported by Transformative Quantum Technologies (TQT) , we are building an open-access, remotely operable trapped-ion quantum computer (QuantumION). The hardware is based on up to sixteen 133Ba+ ion-qubits.
  • Quantum simulation algorithms: We research on classical and quantum algorithms to make quantum simulation more efficient, e.g. by using modern machine learning methods. We collaborate with the Perimeter Institute Quantum Intelligence Laboratory
