Gilles Brassard

Brassard co-developed quantum key distribution and helped generalize quantum search into amplitude amplification and estimation, linking quantum information’s foundations to reusable algorithmic tools.

Université de Montréal

Professor of Computer Science

Read profile
Why included? 3 sources

Brassard’s contributions span how quantum information is protected and how it is processed. The BB84 protocol with Charles Bennett established a quantum approach to distributing secret keys. His work with Peter Høyer, Michele Mosca and Alain Tapp generalized the ideas behind quantum search into amplitude amplification and amplitude estimation. That combination makes him relevant to both the foundations and the algorithmic toolkit of quantum computing. The profile identifies the coauthored procedures and their resource advantages without assuming that a protocol automatically guarantees the security or performance of a particular implementation.

Michele Mosca

Works across quantum algorithms and quantum-safe security, combining foundational results in information processing with programs that help organizations prepare cryptographic systems for future quantum capabilities.

University of Waterloo

Professor, Combinatorics and Optimization

Read profile
Why included? 2 sources

Mosca’s work connects the capabilities of quantum computers with the security transition those capabilities motivate. His research on private quantum channels specifies how classical keys can protect quantum information. At Waterloo, he also helped create programs and industry connections for quantum-safe cryptography, including CryptoWorks21 and evolutionQ. That combination matters because technical security results and real-world migration solve different parts of the same problem. Inclusion recognizes both research and institution building, without predicting when encryption-breaking quantum computers will become available.

About these checks

Linked sources support selected statements in each profile. Research sources include papers and preprints. A source count is not a ranking or a quality score.

The identification check date relates to the recorded professional description. Individual sources have their own check dates. The fixed 2026 selection stays separate from later profile corrections.

THE EDITORIAL VIEW

Why these people.
Why this field.

Quantum computing is shaped by more than headline breakthroughs. Progress also depends on the people who establish its limits, make its systems more reliable and turn difficult ideas into tools others can use.

The QubitWire 100 recognizes contributions across that work. Each profile explains what is being recognized and connects the account to its supporting evidence.
