Reaching the Masses:A New Subdiscipline of App Programmer Education

Programmers’ lack of knowledge and interest in secure development threatens everyone who uses mobile apps. The rise of apps has engaged millions of independent app developers, who rarely encounter any but low level security techniques. But what if software security were presented as a game, or a story, or a discussion? What if learning app security techniques could be fun as well as empowering? Only by introducing the powerful motivating techniques developed for other disciplines can we hope to upskill independent app developers, and achieve the security that we’ll need in 2025 to safeguard our identities and our data

Entanglement, Bell Inequalities and Decoherence in Particle Physics

We demonstrate the relevance of entanglement, Bell inequalities and decoherence in particle physics. In particular, we study in detail the features of the ``strange'' $K^0 \bar K^0$ system as an example of entangled meson--antimeson systems. The analogies and differences to entangled spin--1/2 or photon systems are worked, the effects of a unitary time evolution of the meson system is demonstrated explicitly. After an introduction we present several types of Bell inequalities and show a remarkable connection to CP violation. We investigate the stability of entangled quantum systems pursuing the question how possible decoherence might arise due to the interaction of the system with its ``environment''. The decoherence is strikingly connected to the entanglement loss of common entanglement measures. Finally, some outlook of the field is presented.Comment: Lectures given at Quantum Coherence in Matter: from Quarks to Solids, 42.
