Attackers are recording, and sometimes forging, vast volumes of human communication. Some of this communication is protected by cryptographic systems such as the Rivest–Shamir–Adleman (RSA) system and ...

A key challenge in adiabatic quantum computing is to construct a device that is capable of encoding problem Hamiltonians that are classically intractable, that is, non-stoquastic 13. Such Hamiltonians ...

Bernhard Esslinger explores the dark side of cryptography Figure 1: Kleptographic attacks are possible in each of the components of a cryptosystem shown here. The encapsulation of a black-box ...
