Redshift-space distortions in simulations of the 21-cm signal from the cosmic dawn
Hannah E. Ross, Sambit K. Giri, Keri L. Dixon +3
The 21-cm signal from the Cosmic Dawn (CD) is likely to contain large fluctuations, with the most extreme astrophysical models on the verge of being ruled out by observations from…

Approximate stabilizer rank and improved weak simulation of Clifford-dominated circuits for qudits
Yifei Huang, Peter Love
Bravyi and Gosset recently gave classical simulation algorithms for quantum circuits dominated by Clifford operations. These algorithms scale exponentially with the number of T-gat…

The 21cm bispectrum as a probe of non-Gaussianities due to X-ray heating
Catherine A. Watkinson, Sambit K. Giri, Hannah E. Ross +4
We present analysis of the normalised 21-cm bispectrum from fully-numerical simulations of intergalactic-medium heating by stellar sources and high-mass X-ray binaries (HMXB) durin…
