The mission of the quantum computing group at LNCC is to conduct original research in the fields of quantum computation and quantum information, supervise Ph.D. and master's students, engage in national and international collaborations to enhance the group's research quality, propose innovative techniques, and, if possible, participate in the development of quantum hardware.

To accomplish its mission, the quantum computing group develops computer simulations of quantum computing and quantum systems by utilizing high-performance computing (HPC) with programming languages such as Python, C, OpenCL, Cuda, and Neblina. The group also creates simulators for HPC platforms to support researchers working in quantum computing and quantum mechanics. Additionally, the group employs computer algebra languages and has advanced expertise in Maple.

The group organizes scientific meetings, workshops, and talks on quantum computing and related fields. Members of the group typically teach graduate courses in computing and quantum computing, as well as create educational materials.

Our group is based at the National Laboratory of Scientific Computing (LNCC), an institute affiliated with the Ministry of Science, Technology, and Innovation (MCTI). Located in the Imperial City of Petrópolis, just 45 minutes from Rio de Janeiro, LNCC primarily focuses on research activities in the field of scientific computing. It aims to develop mathematical and computational models to address various scientific and technological challenges.

What is quantum computing? Quantum computing is a subfield of computer science that develops both computer technology based on the principles of quantum theory and the software that runs on quantum computers. By adhering to the laws of quantum mechanics, quantum computers gain immense processing power through their ability to have qubits in multiple states and perform simultaneous tasks. The first ideas about quantum computing were proposed by Paul Benioff and Richard Feynman in the early 1980s. They theorized a computer operating on certain quantum mechanical principles, which would be useful for simulating quantum mechanics itself. In 1985, David Deutsch of Oxford University published a paper describing the quantum Turing machine, and in the early 1990s, he provided the first examples of quantum algorithms faster than their best classical counterparts. Since then, the field has grown exponentially. A large-scale universal quantum computer is still beyond today's technological capabilities. However, in 2019, quantum supremacy, also referred to as quantum advantage, was first claimed to be achieved by Google.
