Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

Heisenberg's uncertainty principle forms a fundamental element of quantum mechanics.
Uncertainty relations in terms of entropies were initially proposed to deal with conceptual …

This book provides the reader with the mathematical framework required to fully explore the
potential of small quantum information processing devices. As decoherence will continue to …

The interest in post-quantum cryptography—classical systems that remain secure in the
presence of a quantum adversary—has generated elegant proposals for new cryptosystems …

Quantum cryptography is the art and science of exploiting quantum mechanical effects in
order to perform cryptographic tasks. While the most well-known example of this discipline is …

This thesis consolidates, improves and extends the smooth entropy framework for non-
asymptotic information theory and cryptography. We investigate the conditional min-and max …

We give the first proof of security for an identity-based encryption (IBE) scheme in the
quantum random oracle model. This is the first proof of security for any scheme in this model …

We initiate the study of quantum-secure digital signatures and quantum chosen ciphertext
security. In the case of signatures, we enhance the standard chosen message query model …

We present a new definition of computationally binding commitment schemes in the
quantum setting, which we call “collapse-binding”. The definition applies to string …

MiniQCrypt is a world where quantum-secure one-way functions exist, and quantum
communication is possible. We construct an oblivious transfer (OT) protocol in MiniQCrypt …
