Quantum metrology can help determine many of today's most pressing security problems by providing new ways of location and timing that are not based on GPS signals that can be easily jammed or tampered with.
FREMONT, CA: Quantum information technology will have a significant effect on national security, touching everything from highly secure communications to quicker code-breaking to better detecting aircraft and submarines. It can be just as transformative in defense and national security as the classical information science that has brought humanity computers and the internet.
The Utilization of Quantum Technologies in National Security
Quantum computing
Quantum computing, the most known quantum technology, notes that; Quantum computers can be used by defense planners to simulate large-scale military operations, by scientists to model complex chemical reactions to prototype new materials, or even by technologists to crack cryptography or advanced artificial intelligence tools.
The danger to today's encryption standards is also recognized as the use of quantum computers would also likely involve the development of new encryption techniques, as many current methods may be susceptible to algorithms running on quantum computers.

Quantum communications
Quantum communication, the method of protecting communications using the concepts of quantum mechanics, is also discussed. Specifically, Quantum Key Distribution (QKD) is one of the most advanced techniques. What is remarkable about QKD is that it can safely exchange a key without the risk of an eavesdropper stealing it from the quantum channel. If the opponent tries to intercept and read the quantum key, the quantum state will collapse, making the intrusion known to both sender and receiver. Technology that can defend against both classic and quantum attacks can accelerate the exchange of encryption keys over long distances while staying stable, which means that it is well suited to protecting national security communications.

Quantum metrology
Quantum metrology, also known as quantum sensing, is the third and final technology. The implementation of quantum ability to improve the precision of measurements can be a real game-changer. The technology can be applied to modern sensors, radars, and other detection devices to provide more capable means of detecting anything from stealth aircraft (quantum RADAR) to submarines (quantum ghost imaging) to underground installations (quantum gravimetry). Quantum metrology can also help determine many of today's most pressing security problems by providing new ways of location and timing that are not based on GPS signals that can be easily jammed or tampered with.
