Institute for Quantum Computing
The Institute for Quantum Computing is an affiliate scientific research institute of the University of Waterloo located in Waterloo, Ontario with a multidisciplinary approach to the field of quantum information processing. IQC was founded in 2002 primarily through a donation made by Mike Lazaridis and his wife Ophelia whose substantial donations have continued over the years. The institute is now located in the Mike & Ophelia Lazaridis Quantum-Nano Centre and the Research Advancement Centre at the University of Waterloo.
It is led by founder and physicist, Raymond Laflamme with researchers based in 6 departments across 3 faculties at the University of Waterloo. In addition to theoretical and experimental research on quantum computing, IQC also hosts academic conferences and workshops, short courses for undergraduate and high school students, and scientific outreach events including open houses and tours for the public.
Mission
The IQC seeks to harness quantum mechanics to develop transformational technologies that will benefit society and become a new engine of economic development in the 21st century. It aims to develop and advance quantum information science and technology at the highest international level through the collaboration of computer scientists, engineers, mathematicians and physical scientists.The institute's three strategic objectives have been stated as:
- To establish Waterloo as a world-class centre for research in quantum technologies and their applications.
- To become a magnet for highly qualified personnel in the field of quantum information.
- To establish IQC as the authoritative source of insight, analysis and commentary on quantum information.
History
At its establishment, the institute was composed of only a handful of researchers from the Departments of Computer Science and Physics. Ten years later, there are more than 200 researchers across six departments within the Faculties of Science, Mathematics, and Engineering at the University of Waterloo.
In 2008, IQC moved into the Research Advancement Centre 1 in the University of Waterloo's Research & Technology Park. In 2010, research operations expanded into the adjacent building, Research Advancement Centre 2.
In 2012, IQC expanded into the Mike & Ophelia Lazaridis Quantum-Nano Centre. The 285,000-square-foot facility is shared with the Waterloo Institute for Nanotechnology, and is built to stringent standards for quantum and nanotechnology experiments. The building was designed by Toronto-based firm Kuwabara Payne McKenna Blumberg Architects.
Research
Research at IQC focuses on three main applications of quantum information science and technology using the physical sciences, mathematics and engineering from both theoretical and experimental perspectives. The three applications are quantum computing, which encompasses the manipulation and storage of quantum information; quantum communication, which is related to the transmission of quantum information; and quantum sensing, which is used to detect signals or stimuli that are present in the nanoscopic world.Areas of research currently studied at IQC include:
- Nanoelectronics-based quantum information processing
- Quantum algorithms
- Quantum complexity
- Quantum cryptography
- Quantum error correction and fault tolerance
- Quantum information theory
- Optical quantum information processing
- Spin-based quantum information processing
