Quantum phenomena have puzzled and delighted scientists for over a century, revealing unique, counter-intuitive characteristics of matter like superposition and entanglement. For four decades, the U.S. National Science Foundation has worked to enable breakthroughs in quantum information science and engineering that harness what researchers have learned about quantum phenomena to develop technologies like quantum computers, sensors, and communications. These quantum technologies will have enormous consequences for the national and global economy. To unleash that potential, researchers must overcome several major, fundamental challenges in quantum information science and engineering. Read more…
