Polemiche intorno a Muratori nell'epistolario Lami-Calogerà
No full texti riferimenti a Muratori nel carteggio Calogerà-Lami si distribuiscono su un lasso di tempo ampio, che non si interrompe con il 1750. Da essi emerge il riconoscimento della statura intellettuale e dell’enorme eredità culturale lasciata dal Modenese. Muratori è lodato per l’erudizione solidissima che è, però, anche l’origine di una libertà di pensiero tanto ampia da suscitare qualche disappunto in Calogerà e in Lami. Una libertà che non nasceva da prese di posizione momentanee e velleitarie, frutto delle convenienze del momento, ma dall’attenta valutazione di fonti che gli palesavano fatti e dati incontestabili

Angelo Calogerà - Giovanni Lami, Carteggio (12 marzo 1743 - 31 maggio 1766). Parte II, 27 giugno 1751 - 31 maggio 1766
No full textSi offre agli studiosi l’edizione critica del carteggio tra Giovanni Lami e Angelo Calogerà, due fra i più importanti giornalisti del Settecento italiano. Il carteggio era rimasto inedito e, per quanto riguarda le lettere di Lami, conservato presso la Biblioteca di San Pietroburgo e difficilmente consultabile. L’edizione è corredata da un apparato critico e da un ampio commento che illumina gli accenni spesso criptici dei due corrispondenti, restituendo un vivido affresco del giornalismo erudito italiano del XVIII secolo
Traduzioni e giornali stranieri nel carteggio Lami-Calogerà,
No full textThe journals of Giovanni Lami and Angelo Calogerà are well known and studied. The private correspondence between the two scholars sheds new light on the cultural mediation work carried out by the two journalists with their journalistic enterprises. It was a complex mediation, not only between Italian Catholic and Transalpine Protestant culture, but also between pro-Jansenists and Jesuit supporters within a Catholic and Italian context. Lami and Calogerà in their journalistic activity found original solutions to support the authority of their newspapers. The use of the correspondence of two of the most important Italian eighteenth-century journalists allows us to better evaluate the line of their periodicals and to understand the reasons for some editorial choices. Calogerà’s position with regard to transalpine literature and periodicals, the subject of his first journalistic enterprises, is particularly interesting
Restoring quantum communication efficiency over high loss optical fibres
No full textIn the absence of quantum repeaters, quantum communication proved to be
nearly impossible across optical fibres longer than due
to the drop of transmissivity below the critical threshold of . However,
if the signals fed into the fibre are separated by a sufficiently short time
interval, memory effects must be taken into account. In this paper we show that
by properly accounting for these effects it is possible to devise schemes that
enable unassisted quantum communication across arbitrarily long optical fibres
at a fixed positive qubit transmission rate. We also demonstrate how to achieve
entanglement-assisted communication over arbitrarily long distances at a rate
of the same order of the maximum achievable in the unassisted noiseless case.Comment: 19 pages, 2 figures. The full technical details, proofs and
additional developments are deferred to the companion paper [F. A. Mele, L.

Quantum Optical Communication in the presence of strong attenuation noise
No full textIs quantum communication possible over an optical fibre with transmissivity
? The answer is well known to be negative if the environment
with which the incoming signal interacts is initialised in a thermal state.
However, in [PRL 125:110504, 2020] the quantum capacity was found to be always
bounded away from zero for all , a phenomenon dubbed "die-hard
quantum communication" (D-HQCOM), provided that the initial environment state
can be chosen appropriately (depending on ). Here we show an even
stronger version of D-HQCOM in the context of entanglement-assisted classical
communication: entanglement assistance and control of the environment enable
communication with performance at least equal to that of the ideal case of
absence of noise, even if is arbitrarily small. These two phenomena
of D-HQCOM have technological potential provided that we are able to control
the environment. How can we achieve this? Our second main result answers this
question. Here we provide a fully consistent protocol to activate the phenomena
of D-HQCOM without directly accessing the environment state. This is done by
sending over the channel "trigger signals", i.e. signals which do not encode
information, prior to the actual communication, with the goal of modifying the
environment in an advantageous way. This is possible thanks to the memory
effects which arise when the sender feeds signals separated by a sufficiently
short temporal interval. Our results may offer a concrete scheme to communicate
across arbitrarily long optical fibres, without using quantum repeaters. As a
by-product of our analysis, we derive a simple Kraus representation of the
thermal attenuator exploiting the associated Lindblad master equation.Comment: 38 pages, 12 figures. The present paper serves as the companion to
the paper [F. A. Mele, L. Lami, and V. Giovannetti. Restoring quantum
communication efficiency over high loss optical fibres. Preprint
arXiv:2204.13128, 2022], by providing proofs of the results stated there and
