Contribution
It constructs MUB-like bases for N-ququart systems and presents a novel tomographic reconstruction protocol with performance analysis.
Findings
The protocol achieves accurate state reconstruction.
Performance is comparable or superior to existing schemes.
Error estimates demonstrate robustness of the method.
Abstract
We construct an informationally complete set of mutually unbiased - like bases for N ququarts. These bases are used in an explicit tomographic protocol which performance is analyzed by estimating quadratic errors and compared to other reconstruction schemes.
