Fundamental limits of electron and nuclear spin qubit lifetimes in an isolated self-assembled quantum dot

Abstract Combining external control with long spin lifetime and coherence is a key challenge for solid state spin qubits. Tunnel coupling with electron Fermi reservoir provides robust charge state control in semiconductor quantum dots, but results in undesired relaxation of electron and nuclear spin...
