The History and Future of Quantum Information

Two of the most important fields in the 20th century have come together to revolutionize the 21st.
 

by Ben P. Stein

When two good things get together, they can create something even better. That’s the case with quantum information—the marriage of quantum physics and computing theory. The National Institute of Standards and Technology (NIST) has contributed to much of its history and is helping to shape its future.

QUANTUM INFORMATION APPLICATIONS
WITHOUT COMPUTERS

You don’t even need a quantum computer for many powerful applications of quantum information. Many useful things can be done with the underlying technology. NIST researchers are developing the technology and exploring applications on multiple fronts.
