Quantum Information Sciences (QIS) are enjoying immense fundamental and applied progress in the last decade with new ideas and techniques allowing precise design and control of quantum systems. Some of the prominent subfields of QIS are quantum algorithms, computing and simulations, communications and cryptography, metrology, chemicals and materials discovery. Importantly, ideas and methods from different fields of science: math, computer science, physics, chemistry, electrical engineering, materials design, and drug discovery, and even philosophy and finance, are coming together in current QIS research. For example, one of the promising applications of quantum computers is solving the electronic structure problem of chemical compounds, with the end goal to reveal their reactivity and function, e.g., as catalysts or energy-rich materials. Development of such quantum algorithms require knowledge in theoretical and computational chemistry, as well as expertise in computational complexity, quantum algorithms and simulations. As additional examples, quantum topological materials are investigated as possible hardware for error-protected qubits; theoretical methods developed to treat chemical dynamics in liquids are used to analyze the thermodynamic cost of quantum information processing. Significantly, theoretical proposals on e.g., quantum sensing are now tested in the lab, and conversely, complex experiments can be modeled and simulated in great details. Given the breadth of topics in QIS, many conferences have a focused theme. At CQIQC, however, we believe that to make breakthroughs in QIS, scientists need to be well-informed in ongoing developments in the different subfields of QIS. CQIQC conference will aim to cater to both senior and junior scientists. The conference will include sessions that will be devoted to different themes, covering foundations and applications, theory and experiment, pure and applied research. Examples of sessions are: Quantum computing and algorithms, quantum dynamics and simulations, quantum thermodynamics, quantum communication and cryptography, quantum sensing and control, quantum hardware and materials. Quantum systems are built from different platforms: atoms, ions and molecules, semiconductors, unconventional materials and quantum fields. The conference will bring leaders from these different platforms to share the current state of the art in QIS, and learn from each other. While much attention is now being given to the technological ramifications of QIS, the conference's foremost objective is to address fundamental questions in the field, e.g., to understand the nature of quantum phenomena, complexity of quantum algorithms, protocols for secure quantum communication, algorithms for quantum molecular simulation. Expected Impact. 1. By bringing together researchers from different subfields of QIS, new ideas- and research projects will be developed. This could be in the form of collaborative research with joint grant applications and exchange of students between institutions. In particular, since many participants in the conference will be from the Toronto area (we project about 30%), we expect enhancement of research activity in QIS in our region. 2. The conference will assist in the training of the next generation of quantum scientists. The conference will provide opportunity to junior scientists in their academic and research career to learn, present their work, network and build collaborations. By ensuring that underrepresented scientists are invited, the conference will have a positive impact on their trajectory. 3. Finally, UofT and the Fields will be recognized for being a centre for QIS research.
