Electron spin qubits are a promising platform for quantum computation.Environmental noise impedes coherent operations by limiting the qubitrelaxation ($T_1$) and dephasing ($T_{\phi}$) times. There are multiple sourcesof such noise, which makes it important to devise experimental techniques thatcan detect the spatial locations of these sources and determine the type ofsource. In this paper, we propose that anisotropy in $T_1$ and $T_{\phi}$ withrespect to the direction of the applied magnetic field can reveal much aboutthese aspects of the noise. We investigate the anisotropy patterns of chargenoise, evanescent-wave Johnson noise, and hyperfine noise in hypotheticaldevices. It is necessary to have a rather well-characterized sample to get themaximum benefit from this technique. The general anisotropy patterns areelucidated. We calculate the expected anisotropy for a particular model of aSi/SiGe quantum dot device.
