Homer nodded: von Neumann's surprising oversight
N. David Mermin, Rüdiger Schack
We review the famous no-hidden-variables theorem in John von Neumann's 1932 book on the mathematical foundations of quantum mechanics. We describe the notorious gap in von Neumann'…
Concrete Security Against Adversaries with Quantum Superposition Access to Encryption and Decryption Oracles
Shahram Mossayebi, Rüdiger Schack
In 2013, Boneh and Zhandry introduced the notion of indistinguishability (IND) in chosen plaintext (CPA) and chosen ciphertext (CCA) attacks by a quantum adversary which is given s…
A Finite de Finetti Theorem for Infinite-Dimensional Systems
Christian D'Cruz, Tobias J. Osborne, Ruediger Schack
We formulate and prove a de Finetti representation theorem for finitely exchangeable states of a quantum system consisting of k infinite-dimensional subsystems. The theorem is vali…
Quantum cryptography: a practical information security perspective
Kenneth G. Paterson, Fred Piper, Ruediger Schack
Quantum Key Exchange (QKE, also known as Quantum Key Distribution or QKD) allows communicating parties to securely establish cryptographic keys. It is a well-established fact that…
Decoherence and linear entropy increase in the quantum baker's map
Andrei N. Soklakov, Ruediger Schack
We show that the coarse-grained quantum baker's map exhibits a linear entropy increase at an asymptotic rate given by the Kolmogorov-Sinai entropy of the classical chaotic baker's…
Classical limit in terms of symbolic dynamics for the quantum baker's map
A. N. Soklakov, R. Schack
We derive a simple closed form for the matrix elements of the quantum baker's map that shows that the map is an approximate shift in a symbolic representation based on discrete pha…
