摘要
We have developed a general method for constructing a set of non-orthogonal bases with equal separations between all different basis' states for N-qubit systems. Using these bases we derive an explicit expression for the optimal tomography in non-orthogonal bases and discuss the amount of nonclassical resources required for the bases preparation and the precision of the reconstructed state. The special two-qubit case is analysed separately.
