Channel-optimized quantum error correction
We develop a theory for finding quantum error correction (QEC) procedures which are optimized for given noise channels. Our theory accounts for uncertainties in the noise channel, ...

Security Aspects of Practical Quantum Cryptography
The use of quantum bits (qubits) in cryptography holds the promise of secure cryptographic quantum key distribution schemes. Unfortunately, the implemented schemes are often operat...

Individual audio channels with single display groupware: effects on communication and task strategy
We introduce a system that allows four users to each receive sound from a private audio channel while using a shared tabletop display. In order to explore how private audio channe...

A tight lower bound for restricted pir protocols
We show that any 1-round 2-server Private Information Retrieval Protocol where the answers are 1-bit long must ask questions that are at least n - 2 bits long, which is nearly equa...
