SCIENCE - Quantum computing? Physicists' new technique for cooling molecules may be a stepping stone to quantum computing

At the heart of next-generation computers may be a collection of ultracold molecules held at temperatures a mere fraction of a degree above absolute zero. By combining two traditional atomic cooling technologies, physicists have pioneered a new technique for bringing normally springy molecules to a frozen standstill. Their results may be an important stepping stone towards future quantum computing.
