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. The QITI laboratory is building a programmable trapped ion quantum simulator with Ytterbium ions, with control at the level of individual atoms for studying problems in quantum many-body physics and computation.

11 – 13 Sept 2019 – Congratulations to Gilbert and Nikhil for successfully defending their master’s thesis!

13 Aug 2019 – Here’s a picture of eight laser-cooled Ytterbium (174 isotope) ions in a linear chain! The image was taken using an off-the-shelf Thorlabs 0.1 NA objective and a cheap (~$300) CCD camera. The ions are approximately 8 microns apart.
