Quantum computers for physics, chemistry, biology and more

Quantum mechanics is at the heart of most physical, chemical and biological phenomena. A quantum computer promises to revolutionize these fields with the potential for discovery of new molecules, novel materials, clean energy, effective medicines and a deeper understanding of nature. I will explain the power of quantum computing with the help of some examples. I will then describe how one can build a machine using different technologies like trapped ions, semiconductor quantum dots etc. with a particular focus on the approach followed in our lab using superconducting thin film devices. Finally I will motivate how quantum computers can help model nature efficiently at a very fundamental level. I will conclude by summarizing the current status of the field and challenges that lie ahead.
