In this paper, we propose an optimization method for the construction of two-qubit and two-qudit quantum gates based on semiconductor position-based charge qubits. To describe the evolution of various quantum states, we use a Hubbard based model and Lindblad formalism. The suggested optimization algorithm uses the time evolution of entanglement entropy and mutual information for the determination of the system parameters to achieve high fidelity gates.

CMOS 电荷量子比特和量子比特:纠缠熵和互信息作为构建 CNOT 和 SWAP 门的优化方法

在本文中,我们提出了一种基于半导体位置电荷量子位构建双量子位和双量子位量子门的优化方法。为了描述各种量子态的演化,我们使用基于哈伯德的模型和 Lindblad 形式主义。建议的优化算法使用纠缠熵和互信息的时间演化来确定系统参数以实现高保真门。
