The proposal of quantum simulation provides a highly effective approach for experimental research on open quantum systems. To date, numerous quantum simulation studies pertaining to open quantum systems have been put forward,including Fanchini et al.’s simulation of a dephasing noise channel utilizing an optical system [1], and Xiong et al.’s realization of a quantum simulation for a non-rotating-wave approximation noise channel, also leveraging an optical system [2].

The standard model of modern cosmology might be cracked by the recent persistent hot debate on the hubble-constant(h_(0))tension,which manifests itself as the sound-horizon(r_(s))tension or absolute-magnitude(M_(B))tension if deeming the origin of the hubble tension from modifying the early or late Universe,*** this study,we achieve a fully model-independent constraint(fitting a model-independent global parameterization to a model-independent inverse distant ladder with a modelindependent high-redshift calibration)on late-time models with strong evidence against homogeneous new physics over theΛ-cold-dark-matter(ΛCDM)*** using this model-independent constraint to calibrate sufficiently local supernovae with corresponding late-time models extrapolated below the homogeneity scale,we find surprisingly that,although both h_(0)tension and MB tension are absent in our local Universe,a combination of h_(0)and M_(B)as the intercept a B of the magnitude-redshift relation exhibits 3~7σtension even for theΛCDM *** aBtension seems to call for local-scale inhomogeneous new physics disguised as local observational systematics.
