The world pending: quantum computers, which for many years have been described in books and films, soon can be used for specific purposes: to optimize the routes of airplanes and buses, to develop new drugs and materials, to involve them in machine learning. 

How does it work? Quantum computers extremely speed up computations thanks to the phenomena of quantum superposition and quantum entanglement. New machines do not operate with bits, which are zeros and ones, but qubits, which can be in these two states at the same time (this is called “superposition”). Therefore, a quantum computer does not need to go through all possible variants of the system states, as modern computer technology does.
