Abstract.
Let X1 and X2 be subspaces of quotients of R \(\oplus\) OH and C \(\oplus\) OH respectively. We use new free probability techniques to construct a completely isomorphic embedding of the Haagerup tensor product \({\rm X}_1 \oplus_h {\rm X}_2\) into the predual of a sufficiently large QWEP von Neumann algebra. As an immediate application, given any 1 < q ≤ 2, our result produces a completely isomorphic embedding of \(\ell_q\) (equipped with its natural operator space structure) into \(L_1({\mathcal{A}})\) with \({\mathcal{A}}\) a QWEP von Neumann algebra.
