Connections Between Mutually Unbiased Bases and Quantum Random Access Codes
arXiv:1709.04898 · doi:10.1103/PhysRevLett.121.050501
Abstract
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.
