Gilles Brassard and Charles Bennett have been awarded the A. M. Turing Award “for their essential role in establishing the foundations of quantum information science and transforming secure communication and computing”. The two will share the US$1-million prize, the Association for Computing Machinery in New York City announced on 18 March.
The two winners have seemingly unrelated research backgrounds: Brassard is a computer scientist at the University of Montreal in Canada, and Bennett is a physicist at IBM Research in Yorktown Heights in New York.
This is the first time that the Turing Award, often described as the most prestigious prize in computer science, has recognized work related to quantum physics. Bennett and Brassard — partly through joint work — began to investigate the power of phenomena that could go beyond what’s possible with non-quantum, or ‘classical’, methods of information technology as far back as the 1970s. “People thought it was just a little crazy,” says Bennett. “It didn’t occur to people that quantum effects could be used to do things that couldn’t be done classically.”
Brassard says the accolade made him "extremely happy". "Had I been asked to choose one recognition at any point in my career, it would have been the Turing Award," he says.
Bennett and Brassard “played a very big part in establishing the foundations of quantum information”, says Stephanie Wehner, a quantum-communications researcher at Delft University of Technology in the Netherlands. “Quantum information is more than a vehicle for classical information. We can do things with it that don’t have a classical analogue.”
