Applying the lessons learned in quantum information theory to gain a better understanding of quantum mechanics itself. Is quantum theory simply a new type of probability theory? Exploring new directions towards combining quantum theory with gravity.

Applications of quantum theory to cryptography and computation; understanding in more concrete, physical terms what quantum theory is telling us about the nature of reality. Applications of information theory to better understand the quantum “wave function”.

Applications of the quantum nature of our universe to potential new technologies like quantum cryptography and quantum computation. In particular, theoretical developments such as fault-tolerant quantum codes and protocols for quantum error correction.

Sensitive information can be valuable to others - from your personal credit card numbers to state and military secrets. Throughout history, sophisticated codes have been developed in an attempt to keep important data from prying eyes. But now, new technologies are emerging based on the surprising laws of quantum physics that govern the atomic scale. These powerful techniques threaten to crack some secret codes in widespread use today and, at the same time, offer new quantum cryptographic protocols which could one day profoundly alter the way we safeguard critical information.

Do ideas about information and reality inspire fruitful new approaches to the hardest problems of modern physics? What can we learn about the paradoxes of quantum mechanics, the beginning of the universe and our understanding of black holes by thinking about the very essence of information? The answers to these questions are surprising and enlightening, but also controversial. The topic of information within physics has involved some of the 20th century\'s greatest scientists in long-running intellectual battles that continue to the present day.

Some things can happen in our Universe, and others cannot. The laws of physics establish the boundary between possibility and impossibility. Physicists naturally spend most of their time thinking about the possible. In this lecture, however, we will make a brief reconnaissance across the frontier to study impossible things and discover the surprising connections between them. We will encounter standard science-fiction devices like time machines and faster-than-light spaceships -- as well as other, less-familiar prodigies including quantum cloners and bounded electromagnetic miracles.

Are you ready for this upgrade? The very foundation of computer science is changing. As Moore\'s Law draws to a close, rules of quantum physics are taking over. Learn how leading researchers are using counterintuitive effects, such as superposition, in their quest to build ultra-powerful quantum computers. You\'ll see how quantum particles behave, are controlled and, ultimately, used to calculate.

The universe computes: every atom, electron, and elementary particle registers bits of information, and every time two particles collide those bits are flipped and processed. By ‘hacking’ the computational power of the universe, we can build quantum computers which store and process information at the level of atoms and electrons. This computational capacity underlies the generation of complex systems, and provides insight into the origin of life and its future.
