Introduction to Quantum Information Theory
... Quantum Information theory is a powerful tool for the study of quantum information. A main question is whether quantum information is more powerful than classical information. A celebrated result by Holevo, shows that quantum information cannot be used to compress classical information. In other wor ...

Quantum Entanglement on the Macroscopic Scale
... • Essentially, if two quantum objects are entangled and we measure some property of one object, then we know the property of the other. • Could this idea be extended to macroscopic objects? • For instance, could we entangle two electrical wires such that measuring the current in one wire instantly g ...
