Quantum mechanics has potential applications in communication and computation. But first a quantum connection — known as entanglement — has to be created between bigger and bigger objects.

Many of the technological developments of the past century are based on the principles of a strange theory called quantum mechanics. This is true for lasers, nuclear reactors, semiconductors and many other systems that have changed our lives.
