Quantum computer science is a branch of science that emerged at the end of the 20th century at the junction of quantum mechanics, theory of algorithms, and information theory. In quantum information science, the general principles and laws governing the dynamics of complex quantum systems are studied. A model of such systems is a quantum computer.
Quantum informatics includes questions of quantum computing and quantum algorithms, the physics of quantum computers, quantum cryptography and quantum information theory, directly concerns the foundations of quantum theory, in particular, the problem of measurement and the description of decoherence. The most important physical phenomenon that is studied in quantum computer science is entangled quantum states and the nonlocal properties of quantum many-body physics generated by them.
The basic concept of classical information theory is a bit, taking the values 0 or 1. Quantum information is represented in qubits ( quantum bit ). Qubits can be in a state that is a superposition of 0 and 1. Several qubits can be in an entangled state.
The most important applications of quantum informatics:
