Holevo information
NettetAnother common de nition which is used for the Holevo Information is the following: De nition 2.4. ˜(E) = H(ˆ B) X x2 ˆ(x)H(˙ x) Now, lets look at a few useful pieces of information about Von Nuemann entropy and Holevo Information Remark 2.5. The Holevo Information of an ensemble is always non-negative, because Von Nuemann entropy is … Nettet1. apr. 2024 · The quantum noise generated by quantum measurement based on the Holevo–Yuen theory on quantum detection [ 8, 9, 10] masks the received signal, resulting in errors. Thus, even if the eavesdropper tries to record the ciphertext, the masking effect of the quantum noise makes it impossible to accurately recover the ciphertext.

See equation (5) of the paper. The Holevo information is defined for a probabilistic mixture of density matrices, or for a cq-state (cq = classical quantum state). Share. Cite. Nettet16. okt. 2024 · Abstract We present a family of easily computable upper bounds for the Holevo (information) quantity of an ensemble of quantum states depending on a reference state (as a free parameter). These upper bounds are obtained by combining probabilistic and metric characteristics of the ensemble.

Holevo's theorem is an important limitative theorem in quantum computing, an interdisciplinary field of physics and computer science. It is sometimes called Holevo's bound, since it establishes an upper bound to the amount of information that can be known about a quantum state (accessible information). … Se mer As for several concepts in quantum information theory, accessible information is best understood in terms of a 2-party communication. So we introduce two parties, Alice and Bob. Alice has a classical Se mer In essence, the Holevo bound proves that given n qubits, although they can "carry" a larger amount of (classical) information (thanks to quantum superposition), the amount of classical information that can be retrieved, i.e. accessed, can be only up to n classical (non … Se mer Let {ρ1, ρ2, ..., ρn} be a set of mixed states and let ρX be one of these states drawn according to the probability distribution P = {p1, … Se mer Consider the composite system that describes the entire communication process, which involves Alice's classical input Se mer • Superdense coding Se mer • Holevo, Alexander S.
