Welcoming the second quantum revolution

Quantum mechanics underlies the transformative technological advances of the last century. This "first quantum revolution" has been enabled by semiconductor devices, where quantum mechanics ultimately governs the conduction of electrons.  Quantum mechanics, with exotic features such as quantum superposition and entanglement, has the potential to be harnessed in new devices that take advantage of the inherent complexity of quantum systems. Scientists are beginning to identify places where this "second quantum revolution" has potential for true impact. I will outline this exciting future, focusing on cases where quantum technologies will allow us to see, probe, and quantify the world in fundamentally new ways.
