Quantum information is related to using quantum mechanical concepts to perform information processing and information transmission. Quantum information processing (QIP) is an exciting research area with numerous applications, including quantum key distribution (QKD), quantum teleportation, quantum and distributed quantum computing, quantum sensing, quantum networking, quantum radar, and quantum machine learning. Quantum information science (QIS) is experiencing rapid development, as judged by the number of published books on QIP, quantum computing, and quantum communications and the numerous conferences devoted solely to QIS. Given the novelty of underlying QIS concepts, this topic is expected to be a subject of interest to many scientists, engineers, governmental agencies, industries, and investors, not just those involved in QIP research. The entanglement represents a unique QIP feature enabling quantum computers to solve problems that are numerically intractable for classical computers, enabling quantum-enhanced sensors with measurement sensitivities exceeding classical limits and providing certifiable data transmission security guaranteed by the laws of quantum mechanics rather than the unproven assumptions used in conventional cryptography for computational security. Preshared entanglement can be used to (1) improve classical channel capacity, (2) enable secure communications, (3) improve sensor sensitivity, (4) enable distributed quantum computing, (5) enable entanglement-assisted distributed sensing, and (6) enable provably secure quantum computer access, as well as perform many other tasks.
