Query: Connections Between Mutually Unbiased Bases and Quantum Random Access
  Codes   We present a new quantum communication complexity protocol, the
promise--Quantum Random Access Code, which allows us to introduce a new measure
of unbiasedness for bases of Hilbert spaces. The proposed measure possesses a
clear operational meaning and can be used to investigate whether a specific
number of mutually unbiased bases exist in a given dimension by employing
Semi--Definite Programming techniques.
