Holevo information
NettetThe HSW theorem states that the classical capacity of a quantum channel can be characterized as its regularized Holevo information : This quantity is difficult to compute and this reflects our ignorance on quantum channels. However, if the Holevo information is additive for a channel , i.e., Nettet4. sep. 2024 · Approaches for approximate additivity of the Holevo information of quantum channels.

NettetAlexander Holevo Original approach to foundations of quantum mechanics via mathematical statistics leading to substantial generalization of standard notion of quantum observable Introduction to the “noncommutative” mathematical statistics providing a methodological basis for quantitative study of quantum measurements NettetWe present a new proof of Holevo's (1973, 1977) coding theorem for transmitting classical information through quantum channels, and its strong converse. The technique is largely inspired by Wolfwitz's (1964) combinatorial approach using types of sequences. As a byproduct of our approach which is independent of previous ones, both in the coding …
Nettet15. jul. 2024 · The Holevo bound is an asymptotically achievable bound when one allows for any measurement strategy, including collective measurements on many copies of the probe. In this work, we introduce a... Nettet15. jul. 2024 · In fact, it was earlier in 1973 that Holevo already initiated the study of quantum communication channels and transmission of classical information through them. This led to the famous Holevo bound [ 3 ], and subsequently to the celebrated Holevo–Shumacher–Westmoreland theorem [ 4, 5 ].

Although Holevo’s theorem does not directly concern the quantum mutual information, it is nevertheless related and indirectly appears in the proof. 12.1.2 Accessible information
NettetThe Holevo bound puts an upper limit on how much information can be contained in a quantum system, using a particular ensemble. Essentially it says that one qubit can …
Nettet2 dager siden · The output Holevo information χ(Φ(b µ)) of a complementary channel is interpreted as a bound on the amount of classical information ”obtained” by the environment (or ”eavesdropper” in terms of secret communications) [7, 9]. Below we will consider different applications of the relations (70)-(73) and (74)-(76). india best cm 2022Holevo'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.
