(a) An arbitrary single-qubit gate as a rotation in the Bloch picture. (b) List of a few common single-qubit gate operations.

Quantum computation exploits the principles of quantum mechanics—superposition, entanglement and interference—to process information in ways that exceed classical limits. In the circuit model, ...

Evolution paths of the single control qubit on the Bloch sphere in the hybrid approach to Grover’s algorithm. Quantum computers are built of elementary operations called quantum gates that are similar ...
