contents Spin qubits have proven to be a feasible candidate for quantum computation, and some realizations of spin qubits already benefit from advanced device manufacturing in the semiconductor industry. Compared to superconducting platforms, spin qubits can operate at higher temperatures from tens of millikelvin up to a few kelvin. However, recent experiments show a non-trivial and often non-monotonic dependence of the spin qubit frequency on the temperature, featuring a region of decreased sensitivity to temperature fluctuations. In this work, we aim to gain insight into the physics behind such temperature shifts in the low-temperature limit. Investigating the spin qubits' interaction with phonon modes of the host material, we can explain some of the key features of the observed behavior and estimate the temperature sweet spot for the qubit frequency shift.
