  If the physics behind dark energy and/or dark matter violates the parity
symmetry assumed in the standard cosmological paradigm, the linear polarization
of the cosmic microwave background (CMB) photons can rotate due to their
coupling to the dark sector. Recent 3$\sigma$ hints of this ``cosmic
birefringence" in the EB spectrum of the CMB polarization motivates us to
pursue new directions to independently validate and characterize the signal.
Here, we explore the prospects to probe cosmic birefringence from small-scale
fluctuations in the CMB using polarized Sunyaev-Zel'dovich (pSZ) tomography. We
find that pSZ can be used to infer the redshift dependence of cosmic
birefringence and also help calibrate the instrumental polarization
orientation. To illustrate the prospects, we show that pSZ tomography may probe
an axion-like dark energy model with masses $m_\phi \lesssim 10^{-32}$eV with
$\mathcal{O}(0.1)$ degrees of rotation between reionization and recombination.
