Chi di noi correndo nell’ansia di un ritardo non ha desiderato per un attimo di teletrasportarsi nel luogo dell’appuntamento? Proprio come facevano i personaggi di Star Trek entrando nella sala teletrasporto dell’ Enterprise e ricomparendo immediatamente in qualche altro punto dell’universo. Forse ci siamo anche chiesti se la scienza e gli sviluppi della tecnologia ci porteranno mai a questo. Gli autori propongono un viaggio nel mondo dei quanti, dove si nascondono possibilità sorprendenti: non solo il teletrasporto di particelle, ma sistemi crittografici a prova della più abile spia, e calcolatori che usano singoli atomi come registri di memoria, capaci di calcoli ritenuti fino a oggi impossibili. I fondamenti della fisica microscopica vengono descritti senza tecnicismi; se ne illustrano applicazioni che, come è successo in passato con il transistor e il laser, trasformeranno radicalmente i nostri calcolatori, le transazioni commerciali e le carte di credito, le comunicazioni, insomma una parte importante della nostra vita di lavoro e di relazione. E scopriremo che a volte la realtà, o meglio l’insieme di potenzialità offerte dalla ricerca scientifica, supera davvero la fantascienza.

To celebrate the 25th anniversary of the seminal 1993 quantum teleportation paper, we are pleased to present research works, reviews, and stories about quantum communication, quantum entanglement, and quantum teleportation: (1) How was quantum teleportation invented? (2) Which teleportation experiments were performed at the Sapienza University in Rome? (3) Can we use joint measurements to generate nonclassical correlations? (4) How is classical sampling related to quantum entanglement? (5) How is classical communication related to a special quantum ensemble? (6) How can simplifying a quantum key distribution protocol make it insecure? (7) Can we teleport a two-qubit quantum state using a nonsymmetric channel? This book includes submissions by some of the most prominent quantum teleportation contributors, including Gilles Brassard, Francesco De Martini, Nicolas Gisin, and William K. Wootters, as well as additional researchers, all presenting their up-to-date insights regarding quantum communication.

"The P-NP problem is the most important open problem in computer science, if not all of mathematics. The Golden Ticket provides a nontechnical introduction to P-NP, its rich history, and its algorithmic implications for everything we do with computers and beyond. In this informative and entertaining book, Lance Fortnow traces how the problem arose during the Cold War on both sides of the Iron Curtain, and gives examples of the problem from a variety of disciplines, including economics, physics, and biology. He explores problems that capture the full difficulty of the P-NP dilemma, from discovering the shortest route through all the rides at Disney World to finding large groups of friends on Facebook. But difficulty also has its advantages. Hard problems allow us to safely conduct electronic commerce and maintain privacy in our online lives. The Golden Ticket explores what we truly can and cannot achieve computationally, describing the benefits and unexpected challenges of the P-NP problem"--
