The mission of the quantum computing group at LNCC is to develop original research in the areas of quantum computation and quantum information, to supervise Ph.D. and master students, to pursue national and international collaborations in order to boost the group's research quality, to propose new techniques, to follow, and if possible to participate in the development of the quantum hardware.

In order to achieve that mission, the quantum computing group develops computer simulations of quantum computing and quantum systems by employing high performance computing (HPC) using the following languages: Python, C, OpenCL, Cuda, Neblina. The group also develops simulators for HPC platforms to be used by researchers working in quantum computing and quantum mechanics. We also use computer algebra languages, with advanced skills on Mathematica and Maple.

The group organizes scientific meetings, workshops, and talks about quantum computing and related areas. Members of the group usually teach graduate courses on computing and quantum computing and produce pedagogic material.

Our group is hosted by the National Laboratory of Scientific Computing (LNCC) which is an institute of the Ministry of Science, Technology and Inovation (MCTI) at the Imperial City of Petrópolis, 45 minutes from Rio de Janeiro. The research activities of LNCC are mainly directed to the area of Scientific Computing, proposing mathematical and computational models to solve scientific and technological problems.

What is quantum computing? Quantum computing is a subarea of computer science that develops both the computer technology based on the principles of quantum theory and the software that runs on the quantum computer. By following the laws of quantum mechanics, the quantum computer gains huge processing power through the ability to be in multiple states and to perform simultaneous tasks. The first ideas about quantum computing were put forward by Paul Benioff and Richard Feynman in early 1980s. They theorized a computer operating with some quantum mechanical principles, which would be useful to simulate quantum mechanics itself. In 1985, David Deutsch of Oxford University published a paper describing the quantum Turing machine, and in early 1990s he was able to give the first examples of quantum algorithms faster than the best equivalent classical algorithms. Since then the area has increased exponentially. An universal quantum computer of large size is still beyond today's technological capability. In 2018, universal quantum computers with more than 50 qubits were built showing that the quantum supremacy will be achieved soon.
