Quantum Cryptography relies on the unique properties of entangled particles, where changes in the state of one particle instantaneously affect the state of the other, regardless of the distance between them.

Quantum Key Distribution (QKD) is a cryptographic protocol that allows two parties to establish a shared secret key using quantum mechanics, ensuring the security of their communication.

Quantum Cryptography offers several advantages over classical cryptography, including increased computational complexity for eavesdropping, enhanced resistance to brute-force attacks, and immunity to quantum attacks.

Entangled particles are primarily used in Quantum Cryptography to generate random keys, which are then employed to encrypt and decrypt messages securely.

Quantum Cryptography faces several challenges, including the high cost of quantum computing devices, the difficulty in generating and manipulating entangled particles, and the susceptibility to noise and environmental disturbances.

While Quantum Cryptography has the potential to revolutionize secure communication in various fields, it is not suitable for developing unbreakable codes for military purposes, as quantum computers could potentially break such codes in the future.

Quantum Key Distribution (QKD) is the process of securely distributing cryptographic keys using quantum mechanics, ensuring that eavesdropping attempts are detectable.

The BB84 Protocol, developed by Charles Bennett and Gilles Brassard in 1984, is a widely used protocol in Quantum Cryptography that enables two parties to establish a shared secret key without revealing it to each other.

Quantum Cryptography is vulnerable to various security threats, including man-in-the-middle attacks, side-channel attacks, and quantum eavesdropping, which can compromise the security of the communication.

The primary goal of Quantum Cryptography is to establish secure communication channels, generate unbreakable cryptographic keys, and protect data from eavesdropping and unauthorized access.

While Quantum Teleportation Protocol is a fundamental concept in quantum mechanics, it is not a type of Quantum Cryptographic protocol.

Quantum Teleportation is the process of transmitting quantum information over long distances by manipulating entangled particles.

Quantum Cryptography has the potential to revolutionize the financial sector by providing secure communication, encrypting sensitive data, and authenticating financial transactions, thereby enhancing security and reducing the risk of fraud.

The primary advantage of Quantum Cryptography over classical cryptography methods is that it provides unconditional security, meaning that it is theoretically impossible to break the encryption even with unlimited computational power.

While Quantum Cryptography has the potential to revolutionize the healthcare sector by providing secure communication and protecting patient data, it is not directly related to the development of new drugs and treatments, which is a field of research in quantum computing.
