In 2017, Karimi and collaborators reported advances in [[High-dimensional quantum communication|quantum communication]]. They demonstrated optimal quantum cloning of high-dimensional states, providing a framework to assess the security of such channels against eavesdropping.{{Cite web |title=Quantum cloning of high-dimensional states |url=https://www.science.org/doi/10.1126/sciadv.1601915 |access-date=2026-05-01 |website=Science Advances |language=en}} In the same year, his team demonstrated high-dimensional [[Quantum key distribution|quantum key distribution]] over an urban free-space link in Ottawa, achieving information rates exceeding one bit per photon.{{Cite web |title=High-dimensional quantum encryption performed in real-world city conditions |url=https://opg.optica.org/optica/fulltext.cfm?uri=optica-4-9-1006&id=372228 |access-date=2026-05-01 |website=Optica |language=en}} |

In 2019, Karimi's team at Ottawa has successfully developed and operated the first [[quantum simulator]] specifically designed to model cyclic (ring-shaped) quantum systems. The team used individual [[photon]]s—quantum of light—to simulate the quantum behavior of [[electron]]s in rings composed of varying numbers of [[atom]]s. The experimental results revealed that the physics governing ring-shaped systems differs fundamentally from that of [[Linear system|linear (line-shaped) systems]].{{Cite web |title=In the blink of an eye: Team uses quantum of light to create new quantum simulator |url=https://www.sciencedaily.com/releases/2019/02/190219143520.htm |access-date=2025-07-27 |website=ScienceDaily |language=en}} |
