An upper bound on the mean-square error for Bayesian parameter estimators (Corresp.)
The estimation of unknown parameters of deterministic time-varying signals contaminated with additive Gausaian white noise is considered, and an upper bound is obtained for the mean-square estimation error. As an example, the theory is applied to the synchronous demodulation of pulse frequency-modulated (PFM) signals in Gaussian white noise. Manuscript received July 3, 1975; revised January 5, ...
متن کاملQuantum error correction for non-maximally entangled states
Quantum states have high affinity for errors and hence error correction is of utmost importance to realise a quantum computer. Laflamme showed that 5 qubits are necessary to correct a single error on a qubit. In a Pauli error model, four different types of errors can occur on a qubit. Maximally entangled states are orthogonal to each other and hence can be uniquely distinguished by a measuremen...
متن کاملMixed maximally entangled states
We find that the mixed maximally entangled states exist and prove that the form of the mixed maximally entangled states is unique in terms of the entanglement of formation. Moreover, even if the entanglement is quantified by other entanglement measures, this conclusion is still proven right. This result is a supplementary to the generally accepted fact that all maximally entangled states are pu...
متن کاملPreservers of Maximally Entangled States
The linear structure of the real space spanned by maximally entangled states is investigated, and used to completely characterize those linear maps preserving the set of maximally entangled states on Mm ⊗Mm, where Mm denotes the space of m ×m complex matrices. Aside from a degenerate rank one map, such preservers are generated by a change of orthonormal basis in each tensor factor, interchangin...
متن کاملTask-Oriented Maximally Entangled States
We introduce the notion of a task-oriented maximally entangled state (TMES). This notion depends on the tasks for which a quantum state is used as the resource. This concept may be more fruitful than that of a general maximally entangled state in the case of a multipartite system. We illustrate this idea by giving an operational definition of maximally entangled states on the basis of communica...
