Roger Penrose,

Quantum Computing Algorithms and Architecture

Some general foundational issues of quantum mechanics are considered and are related to aspects of quantum computation. The importance of quantum entanglement and quantum information is discussed and their curious acausal properties are addressed. The question of quantum state reduction is also considered, and a specific suggestion for a gravitational state–reduction scheme is put forward. A general proposal for an experiment to test this scheme is also suggested.
