As researchers in multiple disciplines explore the untapped potential of quantum technologies, some distinct patterns of usage are emerging. With fully useful capabilities still several years off, experts are weighing the breakthroughs that may come. One key point is that the advanced applications that will come with quantum computing will define the state of the art in future years.

Atoms in a glass cell probed by lasers can act as a microwave receiver in a completely different way than traditional metal antennas, one of many discoveries made by researchers at the CCDC Army Research Laboratory (ARL).

The U.S. Army soldier proceeds methodically, picking his way through dense vegetative growth as he traverses a battlefield that geologically is ages old, but technologically is years in the future. With the enemy rendering satellite-borne GPS signals ineffective, the soldier resorts to his internal position-location unit that pinpoints his spot to the meter. His external sensor suite alerts him to the presence of enemy air and ground forces, but they are far enough away to be of no consequence yet. That raises suspicions in his mind, as they seem to have left the soldier’s area strangely undefended—even unattended.

By connecting two quantum systems, Army and University of Maryland researchers opened the door to brand new tools in the field of quantum communication, useful for timing synchronization between quantum systems, the Army has announced. (Photo credit: U.S. Army photo)

U.S. Army Research Laboratory scientists and University of Maryland researchers recently published a study showing how they combined two different quantum technologies to produce a timing synchronization tool for future quantum networks, the Army has announced. The breakthrough could lead to a hybrid quantum network that combines the best features of different types of quantum systems.

No longer the wave of the future, quantum communications are here today. China recently launched Micius, the world’s first-ever quantum communications satellite capable of securing transmitted data within a high-dimensional quantum encryption.

This development is a “Wow!” There is no known capability to decrypt quantum encryption. This means no one can hack it until quantum technology reaches a point where technology gurus can think of it as another element within the Internet of Things (IoT).

A new era of computing, sensing, modeling and communicating will begin with the advent of viable quantum technologies. Viable quantum technologies will change everything about computers. Harnessing the characteristics of quantum mechanics is bound to unlock mathematical mysteries and enable profound applications.

Today’s military leaders must prepare now for the quantum future.

In December, my monthly blog was an article titled Quantum, Artificial Intelligence, Dilbert and Duct Tape. Quantum interests me. "Dilbert" I read daily, and duct tape saved the protagonist in Andy Weir’s novel "The Martian." It’s not that I understand basic principles of quantum mechanics, but there is so much that quantum mechanics and its associated physics offer that crosses so many technological fields and means for the future of space exploration.
