When I became the first Canadian to delve into the interface of computer science and quantum theory in the late 1970s, there was not the least hint that the discipline I was contributing to creating would thrive today with thousands of researchers worldwide and annual budgets in the billions of dollars. In April 2021, the Government of Canada acknowledged the importance of investing massively in quantum technologies with the announcement of a National Quantum Strategy, recognizing with the commitment of $360 million over seven years that "quantum technologies are at the cutting edge of science and innovation, both in Canada and worldwide". The title of my proposal, Bringing the quantum revolution to fruition, refers to the road still ahead of us. Quantum information technologies bring us the prospect of transmitting and processing information with unconditionally secure communication and computers powerful beyond imagination. For ages, cryptography has been a battleground between codemakers and codebreakers, set on strong mathematical foundations by Shannon in the mid-20th century. However, his theory was rooted in the classical physics of Newton and Einstein. When quantum theory is taken into account, new vistas open up both for codemakers and codebreakers. Is this a blessing or a curse for the protection of privacy? This is the exciting tale of quantum cryptography (my most famous invention, perhaps second only to quantum teleportation), in which codemakers appear to have won, and then of quantum hacking, which exploits the imperfections in the implementation of theoretically perfect protocols, followed by device-independent quantum cryptography, which would restore the codemakers' superiority if only it could be implemented. Quantum cryptography is now widely deployed in China. Meanwhile, post-quantum cryptography attempts to find solutions that would protect classical codemakers against quantum codebreakers. A major aspect of my ongoing research thread has been, and will continue to be, to probe these questions from the perspective of both sides in the battle. As a passionate advocate of privacy, I am also involved in all manners, quantum or classical, by which this inalienable human right can be protected for all. I am also involved in a variety of other aspects of quantum information technology, such as various issues in quantum communication and quantum computing. Furthermore, I believe that a fresh computer science perspective could hold the key to a more satisfactory foundation for quantum theory, as I wrote in my invited opening commentary of the inaugural issue of Nature Physics: "Do the truly fundamental laws of nature concern-not waves and particles-but information?". My ambition is to help Canada remain at the forefront of the Quantum Revolution I initiated four decades ago. Now is the time to continue funding prize-winning fundamental curiosity-driven basic research under the leadership of Canada's quantum information pioneer.
