چکیده
We analyse orthogonal bases in a composite N×N Hilbert space describing bipartite quantum system and look for basis with optimal single-sided mutual state distinguishability. This condition implies that each subsystem the xmlns:mml="http://www.w3.org/1998/Math/MathML">N2 reduced states form regular simplex of maximal edge length, defined respect to trace distance. In case xmlns:mml="http://www.w3.org/1998/Math/MathML">N=2 two-qubit our solution coincides elegant joint measurement introduced by Gisin. derive explicit expressions an analogous constellation xmlns:mml="http://www.w3.org/1998/Math/MathML">N=3 provide general construction forming such xmlns:mml="http://www.w3.org/1998/Math/MathML">HN⊗HN. Our is valid all dimensions which symmetric informationally complete (SIC) generalized known. Furthermore, we show one-party distinguishes leads local tomography linear reconstruction formula. Finally, test tomographical scheme on set three mutually unbiased single qubit using two different IBM machines.

Quantum state and circuit distinguishability with single-qubit measurements
Abstract We show that the Quantum State Distinguishability (QSD), which is a QSZK-complete problem, and the Quantum Circuit Distinguishability (QCD), which is a QIP-complete problem, can be solved by the verifier who can perform only single-qubit measurements. To show these results, we use measurement-based quantum computing: the honest prover sends a graph state to the verifier, and the verifi...
متن کاملA Quantum Evolutionary Algorithm for the Vehicle Routing Problem with Single-sided Time Window Setting
Customer service level is of prime importance in today competitive world and has various dimensions with delivery quality being one of the most important ones. Delivery quality has several parameters such as deliver time window options, time window size, etc. In this paper we focus on one of these parameters, namely time window setting. It has a direct impact upon customer satisfaction and busi...

متن کاملTwo-sided estimates of minimum-error distinguishability of mixed quantum states via generalized Holevo-Curlander bounds
We prove a concise factor-of-two estimate for the failure-rate of optimally distinguishing an arbitrary ensemble of mixed quantum states, generalizing work of Holevo [Theor. Probab. Appl. 23, 411 (1978)] and Curlander [Ph.D. Thesis, MIT, 1979]. A modification of the minimal principle of Concha and Poor [Proceedings of the 6th International Conference on Quantum Communication, Measurement, and C...
