Quantum computers—computers that harness the bizarre laws of quantum mechanics to become vastly more powerful than conventional computers—have been touted as the next leap in technology. Although useful quantum-computing technology is probably years—and possibly decades—away, physicists like Jason Alicea, who joined Caltech's faculty this fall as an associate professor of theoretical physics, are working hard to make it a reality. Alicea's research involves translating purely theoretical ideas into real-life experiments and applications. He recently answered a few questions about himself and his research.
