The article discusses the importance of quantum communication in protecting sensitive information from cybercrime and eavesdropping. Quantum communication leverages the principles of quantum physics, particularly the concept of qubits, which can exist in multiple states simultaneously, allowing for more secure data transmission. Quantum Key Distribution (QKD) is highlighted as a key application of quantum cryptography, where photons are used to exchange keys securely. The article also addresses the challenges and current state of quantum communication, including the high cost and robustness issues of QKD systems. It mentions the efforts of Indian institutions and organizations, such as the Department of Science and Technology (DST) and the Indian Space Research Organization (ISRO), in developing quantum technologies and infrastructure. The conclusion emphasizes the potential of quantum computing and communication to revolutionize data protection and encryption, while also acknowledging the significant technological and conceptual challenges that need to be overcome.The article discusses the importance of quantum communication in protecting sensitive information from cybercrime and eavesdropping.
