Assume Alice and Bob share some bipartite d-dimensional quantum state. A wellknown result in quantum mechanics says that by performing two-outcome measurements, Alice and Bob can produce correlations that cannot be obtained locally, i.e., with shared randomness alone. We show that by using only two bits of communication, Alice and Bob can classically simulate any such correlations. All previous...

Recently, block-based programming languages like Alice, Scratch and Blockly have become popular tools for programming education. There is substantial research showing that block-based languages are suitable for early programming education. But can block-based programs be smelly too? And does that matter to learners? In this paper we explore the code smells metaphor in the context of block-based...

We show that, despite the fact that Alice&Bob;–notation does not include explicit control flowconstructs, it is possible to make some of these aspects explicit and thus produce formal protocolmodels without having to resort to more expressive protocol description languages. We introducea notion of incremental symbolic runs to formally handle message forwarding and conditionalabor...

eShadow is a storytelling tool that can be used from both adults and children in order to create, record, share and watch digital shadow theater plays. It is based on the traditional Greek Shadow Theatre, which has a long history of usage in entertainment and education, particularly pre-school and primary school education. We present our experience from the use of eShadow in the ALICE ALPPs con...

Since its release in 1999, the LHC experiments have been evaluating Geant4 in view of adopting it as a replacement for the obsolescent Geant3 transport MonteCarlo. The ALICE collaboration has decided to perform a detailed physics validation of elementary hadronic processes against experimental data already used in international benchmarks. In one test, proton interactions on different nuclear t...

Alice and Bob live in the forest. To sustain themselves, they collect fruits and berries and snare an occasional animal. The nights get cold, but Alice is a skillful fire-builder. Bob has never mastered this art. His fires fizzle and he never seems to collect the right kind of wood. Alice divides her time between collecting food and gathering wood. She does this in such a way that her marginal ...

We study the problem of searching on data that is encrypted using a public key system. Consider user Bob who sends email to user Alice encrypted under Alice’s public key. An email gateway wants to test whether the email contains the keyword “urgent” so that it could route the email accordingly. Alice, on the other hand does not wish to give the gateway the ability to decrypt all her messages. W...

A sequence S is nonrepetitive if no two adjacent blocks of S are the same. In 1906 Thue proved that there exist arbitrarily long nonrepetitive sequences over 3 symbols. We consider the online variant of this result in which a nonrepetitive sequence is constructed during a play between two players: Bob is choosing a position in a sequence and Alice is inserting a symbol on that position taken fr...

Alice is the LHC experiment dedicated to heavy ion (Pb, Ca) physics. Alice will be installed in point 2 of LHC, the former point 2 of LEP. The luminosity at the interaction point will be in the order of 10 (10 for p–p). Consequently, the radiation level in Alice will be comparatively low. We will use the existing infrastructure. Therefore, no noticeable civil engineering work will be necessary....
