This project is a part of ESF FoNE CPR 'SpiCo' which aims to investigate spin-dependent coherent transport in mesoscale semiconductor systems and search for methods to control electron spin states in quantum dots and wires of new materials aiming to develop a viable approach to scalable quantum information processing.Further progress towards the control of spin requires understanding of spin dynamics and kinetic processes in quantum nanostructures on the fundamental level and their interplay with quantum transport characteristics in a broad range of materials (such as InAs-based quantum wells and wires, ferromagnetic semiconductors). Within SpiCo, we aim (a) to develop schemes for determining spin-related material parameters in new materials and structures (g-factor, spin-orbit coupling strength) via transport measurements; (b) to develop theory of electron spin dynamics, de-coherence and relaxation in quantum dot and double-dot semiconductor spin qubits; and (c) to find conditions for incoherent and coherent transfer of spin in nano/micro- circuits and methods of detection of spin currents.

这个项目是ESF Fone CPR‘SpiCo’的一部分，该项目旨在研究介观尺度半导体系统中与自旋相关的相干输运，并寻找控制新材料量子点和量子线中电子自旋态的方法，旨在开发一种可行的可扩展量子信息处理方法。进一步控制自旋需要在基本水平上了解量子纳米结构中的自旋动力学和动力学过程，以及它们与广泛材料(如InAs基量子井和量子线、铁磁半导体)中的量子输运特性的相互作用。在SPICo中，我们的目标是(A)发展通过输运测量来确定新材料和结构中与自旋相关的材料参数(g因子，自旋-轨道耦合强度)的方案；(B)发展电子自旋动力学、量子点和双点半导体自旋量子位中的去相干和弛豫理论；以及(C)寻找在纳米/微电路中自旋的非相干和相干转移的条件和自旋电流的检测方法。
