That openness in turn can beinterpreted as the openness of the present as a different concept of truth recollectingHeidegger’s one as “unconcealment” (ἀλήθεια). Quantum information as what is conserved canbe thought as the conservation of that openness.

Time Future

Quantum mechanics involves a generalized form of information, that of quantum information. It is the transfinite generalization of information and representable by transfinite ordinals. The physical world being in the current of time shares the quality of “choice”. Thus quantum information can be seen as the universal substance of the world serving to describe uniformly future, past, and thus the present as the frontier of time. Future is represented as a coherent whole, present as a choice among infinitely many alternatives, and past as a well-ordering obtained as a result of a series of choices. The concept of quantum information describes the frontier of time, that “now”, which transforms future into past. Quantum information generalizes information from finite to infinite series or collections. The concept of quantum information allows of any physical entity to be interpreted as some nonzero quantity of quantum information. The fundament of quantum information is the concept of ‘quantum bit’, “qubit”. A qubit is a choice among an infinite set of alternatives. It generalizes the unit of classical information, a bit, which refer to a finite set of alternatives. The qubit is also isomorphic to a ball in Euclidean space, in which two points are chosen.

Realistic Situation

In a realistic situation, the secret sharing of classical or quantum information will involve the transmission of this information through noisy channels. We consider a three qubit pure state. This state becomes a mixed-state when the qubits are distributed over noisy channels. We focus on a specific noisy channel, the phase-damping channel. We propose a protocol for secret sharing of classical information with this and related noisy channels. This protocol can also be thought of as cooperative superdense coding. We also discuss other noisy channels to examine the possibility of secret sharing of classical information.

Life Movement

AbstractIn French, the verb "to live" designates both being alive and the experience of something. This ambiguity has a philosophical meaning. The task of a phenomenology of life is to describe an originary sense of living from which the very distinction between life in the intransitive sense and life in the transitive, or intentional, sense proceeds. Hans Jonas is one of those rare authors who has tried to give an account of the specificity of life instead of reducing life to categories that are foreign to it. However, the concept of metabolism, by which Jonas characterizes vital activity, attests to a presupposition as to life: life is conceived as self-preservation, that is, as negation of death, in such a way that life is, in the end, not thought on the basis of itself. The aim of this article is to show that life as such must be understood as movement in a radicalized sense, in which the living being is no more the subject than the product. All living beings are in effect characterized by a movement, which nothing can cause to cease, a movement that largely exceeds what is required by the satisfaction of needs and that, because of this, bears witness to an essential incompleteness. This incompleteness reveals that life is originarily bound to a world. Because the world to which the living being relates is essentially non-totalizable and unpresentable, living movement can not essentially complete itself. Thus, in the final analysis, life must be defined as desire, and in virtue of this view, life does not tend toward self-preservation, as we have almost always thought, but toward the manifestation of the world.

The encoding of information in time intervals of an echelon of laser pulses of an object pulse in the optical echo processor is considered. The measures of information are introduced to describe the transformation of classical information in quantum information. It is shown that in the description of information transformation into quantum information, the most appropriate measure is a measure of quantum information based on the algorithmic information theory.

This paper explores an event-based version of quantum mechanics which differs from the commonly accepted one, even though the usual elements of quantum formalism, e.g., the Hilbert space, are maintained. This version introduces as primary element the occurrence of micro-events induced by usual physical (mechanical, electromagnetic and so on) interactions. These micro-events correspond to state reductions and are identified with quantum jumps, already introduced by Bohr in his atomic model and experimentally well established today. Macroscopic bodies are defined as clusters of jumps; the emergence of classicality thus becomes understandable and time honoured paradoxes can be solved. In particular, we discuss the cat paradox in this context. Quantum jumps are described as temporal localizations of physical quantities; if the information associated with these localizations has to be finite, two time scales spontaneously appear: an upper cosmological scale and a lower scale of elementary "particles''. This allows the interpretation of the Bekenstein limit like a particular informational constraint on the manifestation of a micro-event in the cosmos it belongs. The topic appears relevant in relation to recent discussions on possible spatiotemporal constraints on quantum computing.

Random Keys

The lack of perfect randomness can cause significant problems in securing communication between two parties. McInnes and Pinkas \cite{McInnesPinkas-ImpossibilityofPrivate-1991} proved that unconditionally secure encryption is impossible when the key is sampled from a weak random source. The adversary can always gain some information about the plaintext, regardless of the cryptosystem design. Most notably, the adversary can obtain full information about the plaintext if he has access to just two bits of information about the source (irrespective on length of the key). In this paper we show that for every weak random source there is a cryptosystem with a classical plaintext, a classical key, and a quantum ciphertext that bounds the adversary's probability $p$ to guess correctly the plaintext strictly under the McInnes-Pinkas bound, except for a single case, where it coincides with the bound. In addition, regardless of the source of randomness, the adversary's probability $p$ is strictly smaller than $1$ as long as there is some uncertainty in the key (Shannon/min-entropy is non-zero). These results are another demonstration that quantum information processing can solve cryptographic tasks with strictly higher security than classical information processing.

Information can be considered as the most fundamental, philosophical,physical and mathematical concept originating from the totality by means of physicaland mathematical transcendentalism (the counterpart of philosophicaltranscendentalism). Classical and quantum information, particularly by their units, bitand qubit, correspond and unify the finite and infinite. As classical information isrelevant to finite series and sets, as quantum information, to infinite ones. Afundamental joint relativity of the finite and infinite, of the external and internal is tobe investigated. The corresponding invariance is able to define physical action and itsquantity only on the basis of information and especially: on the relativity of classicaland quantum information. The concept of transcendental time, an epoché in relation tothe direction of time arrow can be defined. Its correlate is that information invariant tothe finite and infinite, therefore unifying both classical and quantum information.

Fundamental Physical

Humean Supervenience (HS) is a metaphysical model of the world according to which all truths hold in virtue of nothing but the total spatiotemporal distribution of perfectly natural, intrinsic properties. David Lewis and others have worked out many aspects of HS in great detail. A larger motivational question, however, remains unanswered: As Lewis admits, there is strong evidence from fundamental physics that HS is false. What then is the purpose of defending HS? In this paper, we argue that the philosophical merit of HS is largely independent of whether it correctly represents the world’s fundamental structure. In particular, we show that insofar as HS is an apt model of the world’s higher-level structure, it thereby provides a powerful argument for reductive physicalism and explains otherwise opaque inferential relations. Recent criticism of HS on the grounds that it misrepresents fundamental physical reality is, therefore, beside the point.
