We provide a natural BMO-criterion for the $L_2$-boundedness ofCalder\'on-Zygmund operators with operator-valued kernels satisfying asymmetric property. Our arguments involve both classical and quantumprobability theory. In the appendix, we give a proof of the $L_2$-boundednessof the commutators $[R_j,b]$ whenever $b$ belongs to the Bourgain'svector-valued BMO space, where $R_j$ is the $j$-th Riesz transform. A commoningredient is the operator-valued Haar multiplier studied by Blasco and Pott.
