Minimum error discrimination of Pauli channels
Abstract. We solve the problem of discriminating with minimum error probability two given Pauli channels. We show that, differently from the case of discrimination between unitary transformations, the use of entanglement with an ancillary system can strictly improve the discrimination, and any maximally entangled state allows to achieve the optimal discrimination. We also provide a simple neces...
متن کاملStructure of minimum-error quantum state discrimination
Distinguishing different quantum states is a fundamental task having practical applications in information processing. Despite the effort devoted so far, however, strategies for optimal discrimination are known only for specific examples. In this paper we consider the problem of minimum-error quantum state discrimination where one attempts to minimize the average error. We show the general stru...
متن کاملMinimum-error discrimination between mixed quantum states
We derive a general lower bound on the minimum-error probability for ambiguous discrimination between arbitrary m’s mixed quantum states with given prior probabilities. When m = 2, this bound is precisely the well-known Helstrom limit. Also, we give a general lower bound on the minimum-error probability for discriminating quantum operations. In particular, we show necessary and sufficient condi...
متن کاملGeneralizations of Pauli channels
The Pauli channel acting on 2 2 matrices is generalized to an n-level quantum system. When the full matrix algebraMn is decomposed into pairwise complementary subalgebras, then trace-preserving linear mappingsMn !Mn are constructed such that the restriction to the subalgebras are depolarizing channels. The result is the necessary and su cient condition of complete positivity. The main examples ...
متن کاملSpeech trajectory discrimination using the minimum classification error learning
In this paper, we extend the maximum likelihood (ML) training algorithm to the minimum classification error (MCE) training algorithm for discriminatively estimating the state-dependent polynomial coefficients in the stochastic trajectory model or the trended hidden Markov model (HMM) originally proposed in [2]. The main motivation of this extension is the new model space for smoothness-constrai...
