Optospintronic control of spin qubits in nuclear spin free hosts

Abstract

University of Iowa propose to theoretically investigate optical and electrical initialization, manipulation and readout of coherent spin centers in Se and S containing hosts, focusing on rare-earth, transition-metal and shallow (halide) dopants in ZnS, ZnSe, CeS2 and CeSe2, as well as the magnetic semiconductors Zn1-xMnxS and Zn1-xMnxSe. We anticipate these magnetic semiconductors can efficiently initialize the spin centers through spin-selective transport. We will investigate mechanisms of highly efficient electrical readout of the spin state based on using the spin-correlated dipole to release a transport bottleneck originating from Pauli spin blockade. These studies of the fundamental optical and electrical responses of coherent spin centers in a flexible environment with low charge noise will clarify which systems are worth further investigation and materials development.
