In the previous chapter, I discussed the state of a qubit and what putting that qubit in superposition does to its state. You learned about the complex nature of that state and how to represent it using some linear algebra and the Bloch sphere.Hooyberghs, Johnny...
Quantum Gates and Circuits 来自 掌桥科研 喜欢 0 阅读量: 71 作者: DiVincenzo,P D. 摘要: A historical review is given of the emergence of the idea of the quantum logic gate from the theory of reversible Boolean gates. I highlight the quantum XOR or controlled NOT as the fundamental two-...
单量子比特门(1-Qubit Gates):作用在一个二维量子系统上的任意酉算符。 泡利门(Pauli gates): σ0≡I≡[1001],σ1≡σx≡X≡[0110],σ2≡σy≡Y≡[0−ii0],σ3≡σz≡Z≡[100−1] 对泡利门取幂(exponentiate),可以得到一类特殊的单量子比特门——旋转门(rotation gates)。它们与一个向量在布...
Quantum volume measures the largest quantum circuit that can pass a quantum volume test. The quantum volume test asks the quantum computer to run circuit with random gates and measures how often the circuits output the expected outcomes. However, as we continue scaling up quantum processors, it’...
