Recent advancements in quantum cryptography include the development of quantum key distribution (QKD), which allows two parties to share encryption keys securely, making eavesdropping detectable. Researchers have achieved longer-distance QKD, enabling secure communication over vast networks, and integrated quantum networks that function alongside classical systems. Additionally, advancements in quantum algorithms promise improved cryptographic techniques, including post-quantum cryptography strategies designed to protect against potential quantum threats to current encryption methods. These developments pave the way for a more secure digital future.
