铜(Ⅱ)-α-氨基酸(5-取代邻菲咯啉)-L-苏糖酸三元配合物的稳定性研究

在２９８Ｋ，Ｉ＝０．１ｍｏｌ／ＬＫＮＯ３条件下测定了Ｌ－苏糖酸－α－氨基酸（５－取代邻菲咯啉）－铜（Ⅱ）三元配合物的生成常数．实验表明，生物配体α－氨基酸及Ｌ－苏糖酸具有良好的相容性，其三元配合物的稳定性大于相应二元配合物的稳定性．在较宽的ｐＨ值范围内，三元配合物的含量显著大于二元配合物的含量．即Ｌ－苏糖酸能作为金属离子的载体，使金属离子易于与氨基酸或蛋白质结合而被动物吸收利用．α－氨基酸及Ｌ－苏糖酸间的相容性及其三元配合物的稳定常数随α氨基酸的质子化常数及其二元配合物的稳定常数增加而增加，二者间存在良好的直线自由能关系．而在Ｌ－苏糖酸－５－取代邻菲咯啉－铜（Ⅱ）三元配合物中，由于ｄ－ｐ反馈π键的存在，三元配合物的稳定常数随取代邻菲咯啉质子化常数的增加而降低，二者之间也存在良好的直线自由能关系．     

Quantum state transfer via a hybrid solid–optomechanical interface

We propose a scheme to implement quantum state transfer between two distant quantum nodes via a hybrid solid–optomechanical interface. The quantum state is encoded on the native superconducting qubit, and transferred to the microwave photon, then the optical photon successively, which afterwards is transmitted to the remote node by cavity leaking,and finally the quantum state is transferred to the remote superconducting qubit. The high efficiency of the state transfer is achieved by controllable Gaussian pulses sequence and numerically demonstrated with theoretically feasible parameters.Our scheme has the potential to implement unified quantum computing–communication–computing, and high fidelity of the microwave–optics–microwave transfer process of the quantum state.
