Bloch sphere

Bloch sphere
布洛赫球面
The method comprises the steps of: selecting four consecutive qubits from a linear chain; constructing a 2×2 box cluster by applying Hadamard rotations to the second qubit and the third qubit, followed by applying a swap operation between the second qubit and the third qubit, thereby effectively creating a bond between the first qubit and the fourth qubit; and measuring (along the z-axis of the Bloch sphere, where the Bloch sphere is a geometrical representation of the pure state space of a multi-level quantum mechanical system) the second qubit thereby deleting bonds between the second qubit and the third qubit, and between the second qubit and the fourth qubit.
一个量子比特是一个由两个线性独立态构成的量子系统，[...] 设|Ψ⟩为任意一个量子比特，[...] 量子比特|Ψ⟩也能够以三位欧式空间单位球面上的点表示，该球面被称为布洛赫球面 (Bloch Sphere)。
