A new quantum cryptography scheme for secure encryption

A main focus of quantum cryptography is the use of principles of quantum mechanics to encrypt messages. Such a concept may seem quite daunting to many, but not to Rabib Islam, a promising MSc graduate who made significant contributions to this area of mathematics.

With the guidance of his supervisor Professor Anne Broadbent, Rabib recently completed his MSc degree by presenting his thesis on “Quantum Encryption with Certified Deletion.” With Professor Broadbent, Rabib developed a new quantum cryptographic scheme, which satisfies a new security notion. This new notion is called certified deletion, and it can only be achieved by using quantum information.

As a recent graduate fascinated by quantum encoding, Rabib rapidly found employment as a Data Scientist with the Government of Canada. In this role, Rabib uses probabilistic graphical models to analyze social network data. Last summer, he participated in the QCrypt 2020 conference, an annual international scientific conference that presents the previous year’s top results in quantum cryptography. QCrypt brings together researchers from all over the world to present their recent scientific discoveries in the field, along with companies who showcase their latest relevant technology. Rabib was selected to present his work on certified deletion.

Looking back, Rabib thanks his supervisor, Professor Anne Broadbent, for her patience, wisdom and insight, which contributed significantly to his success. He is grateful for his colleagues in Ottawa and for all their engaging discussions.

Finally, Rabib understands the challenges that come with pursuing research and wants to let future students know that, “it may take a thousand steps to get to your goal. Wherever you are on your journey, just focus on taking the next step.”
