      International audience ; How many copies of a quantum process are necessary and sufficient to construct an approximate classical description of it? We extend the result of Surawy-Stepney, Kahn, Kueng, and Guta (2022) to show that Õ(d^6 /\epsilon^2) copies are sufficient to learn a d-dimensional quantum channel to within ε in the diamond norm. Moreover, we show that Ω(d^6 /\epsilon^2) copies are necessary for any strategy using incoherent non-adaptive measurements. This lower bound applies even for ancilla-assisted strategies.
