On the power of multipartite entanglement for pseudotelepathy
Gilles Brassard, Xavier Coiteux-Roy, Rémi Ligez
As early as 1935, Schrödinger recognized entanglement as ``not one but rather the characteristic trait of quantum mechanics, the one that enforces its entire departure from classic…
Temperature as Joules per Bit
Charles Alexandre Bédard, Sophie Berthelette, Xavier Coiteux-Roy +1
In statistical mechanics, entropy is defined as a fundamental quantity. However, its unit, J/K, involves that of temperature, which is only subsequently defined - and defined in te…
Unconditional Proofs-of-Work and Other Possibilities of Thermodynamic Cryptography
Xavier Coiteux-Roy, Stefan Wolf
In line with advances in recent years about realizing cryptographic functionalities in an information-theoretically secure way from physical phenomena and laws, we propose here to…
On the Advantage of Irreversible Processes in Single-System Games
Xavier Coiteux-Roy, Stefan Wolf
The CHSH no-signalling game studies Bell nonlocality by showcasing a gap between the win rates of classical strategies, quantum-entangled strategies, and no-signalling strategies.…
The RGB No-Signalling Game
Xavier Coiteux-Roy, Claude Crépeau
Introducing the simplest of all No-Signalling Games: the RGB Game where two verifiers interrogate two provers, Alice and Bob, far enough from each other that communication between…
