Kvantumszámítás

Kvantumszámítás, or quantum computing in English, is a field that explores the use of quantum mechanical phenomena such as superposition and entanglement to perform calculations. Unlike classical computers that use bits representing either 0 or 1, quantum computers utilize quantum bits, or qubits. Qubits can exist in a superposition of both 0 and 1 simultaneously, allowing for a potentially exponential increase in computational power for certain types of problems.

Entanglement is another key quantum phenomenon exploited in quantum computing. When qubits are entangled, their states are correlated, even when separated by large distances. This interconnectedness can be leveraged to perform complex operations and solve problems that are intractable for even the most powerful classical supercomputers. Areas where quantum computing is expected to have a significant impact include drug discovery, materials science, financial modeling, and cryptography.

Developing stable and scalable quantum computers presents significant engineering challenges. Qubits are extremely sensitive to environmental noise, which can cause errors. Researchers are exploring various physical implementations for qubits, including superconducting circuits, trapped ions, and topological qubits, each with its own advantages and disadvantages. The field is still in its early stages, but rapid progress is being made, with the potential to revolutionize many scientific and technological domains.
