MORE than a century after its birth, quantum theory is as perplexing as ever, and recent lab results have only underscored just how strange it is. No one is better qualified to describe the weirdness than University of Vienna physicist Anton Zeilinger, director of the Austrian lab where many of these experiments were done.

We now know, for example, that quantum entanglement 鈥� dismissed by Einstein as 鈥渟pooky action at a distance鈥� 鈥� is real; a quantum system can indeed be in two states at the same time. Physicists can also transfer information from one quantum system to another, a feat known as quantum teleportation.

Zeilinger is at his best when detailing the experiments behind these remarkable results. He also examines the philosophical issues they raise; questions that could well take another century to answer.
