In this paper, we show how informationcausality leads to Tsirelson bounds in a much easierway. Furthermore, a series of new Tsirelson bounds arethen derived. We then define the communication protocolsbased on Random access code (RAC) and No‐signalingbox (NS‐box) and then derive the objects for the communicationcomplexity of symmetric quantum channels withi.i.d.(independent identically distribution) and uniform inputmarginal probabilities, consequently we obtain themulti‐level Bell‐type inequality. Deep ramifications concerningnon‐local quantum computation are also found anddiscussed.
