Quantum computers are made up of many entities that, not only interact with each other but also with the outside world. These interactions give quantum computers the power they need to surpass classical computers, but at the same time make them difficult to control due to a phenomenon called quantum decoherence, or in other words, noise. In this project, researchers develop noise-resistant algorithms, paving the way for currently available quantum computers to solve hard problems in cryptography, and to study chemical processes for the development of new materials and medicine more effectively than currently possible.
