Quantum information technology

The basis for quantum information theory is quantum physics, which helped create remarkable technologies such as the transistor and the laser. In time, these were transformed into smaller and smaller devices—home computers, then smartphones—that reshaped human culture. Quantum information technology is now emerging in many new forms, including quantum computing (a new way to pack even more information and processing power into even smaller circuits), quantum cryptography (which promises “unhackable” communications), and ultrasensitive devices to detect biological and chemical changes in the body and the environment. Work in this center seeks to translate what we know—and are learning—about the smallest scale of the physical world into technologies that will again reshape our lives.
