Quantum technologies harness the principles of quantum mechanics to develop new tools and applications. These technologies include quantum computing, which uses quantum bits or qubits to perform calculations much faster than traditional computers, and quantum communication, which enables secure data transmission through quantum encryption. Another area is quantum sensing, which improves measurement precision by exploiting quantum states. These advancements have the potential to revolutionize fields such as cryptography, medicine, and materials science, leading to breakthroughs in how we process information and interact with the world around us.
