4.4 通用量子门(Universal quantum gate) 在经典的计算中,仅需与、或、非三种运算就可完成所有的逻辑操作,我们说这三种运算对于经典计算是普适的或者通用的(universal)。 对于量子计算来说,也有类似的说法,如果任意的酉操作都可以通过某几个基本的门的组合来实现或者以任意精度来逼近的话,我们就称这组量子门是普适...

Quantum computers can be protected from noise by encoding the logical quantum information redundantly into multiple qubits using error-correcting codes1,2. When manipulating the logical quantum states, it is imperative that errors caused by imperfect ope

We first provide some preliminaries about quantum channels, the fidelity of implemented noisy gates, and the relationship between the fidelity of a gate and the channel spectrum of its noisy implementation. Consider a quantum gateUacting on ad-dimensional space with eigenvalues\({e}^{i{\lambda }...
We describe a method for achieving arbitrary 1-qubit gates and controlled-NOT gates within the context of the Single Cooper Pair Box (SCB) approach to quantum computing. Such gates are sufficient to support universal quantum computation. Quantum gate operations are achieved by applying sequences of...
Quantum PhysicsWe construct a Universal Quantum Entanglement Concentration Gate (QEC-Gate). Special times operations of QEC-Gate can transform a pure 2-level bipartite entangled state to nearly maximum entanglement. The transformation can attain any required fidelity with optimal probability by adjusting...
they cannot be universal for quantum computation by braiding alone. Based on our knowledge of the images of the braid group representations, we set up three qutrit computational models. Supplementing braidings with some measurements and ancillary states, we find a universal gate set for each model...
We will find exact minimum solutions to some well-known operators and also to new gates in order to form libraries of universal gates for mv quantum circuit synthesis. The exhaustive search creates the gate as a cascade starting from input signals of the function and next adds sequentially ...
