The counter-intuitive aspects of quantum physics have been for long illustrated by thought
experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now …

Just as “classical” information technology rests on a foundation built of interconnected
information-processing systems, quantum information technology (QIT) must do the same. A …

The key challenge in experimental quantum information science is to identify isolated
quantum mechanical systems with long coherence times that can be manipulated and …

The practical construction of scalable quantum-computer hardware capable of executing
nontrivial quantum algorithms will require the juxtaposition of different types of quantum …

Quantum information science involves the storage, manipulation and communication of
information encoded in quantum systems, where the phenomena of superposition and …

An outstanding goal in quantum information science is the faithful map** of quantum
