The following are some of the potential drawbacks and limitations of quantum cryptography:
Quantum Key Distribution (QKD):
The primary application of quantum cryptography is Quantum Key Distribution, a process that enables two parties to produce a shared secret key securely. This key can then be used for encrypted communication.
Quantum cryptography relies on the behavior of quantum particles, particularly photons. Photons can exist in multiple states simultaneously, a phenomenon known as superposition, and their properties change when observed, providing a basis for secure communication.
The Heisenberg Uncertainty Principle plays a crucial role in quantum cryptography. It states that certain pairs of properties, such as position and momentum, cannot both be precisely determined simultaneously. This principle enhances the security of quantum communication by detecting any attempt to intercept information.
Quantum entanglement involves the correlation of quantum states between particles, even when separated by large distances. Utilizing entangled particles enhances the security of quantum communication, as any disturbance to one particle will affect its entangled partner, signaling potential eavesdropping.
Unlike classical cryptographic methods that rely on mathematical complexity, quantum cryptography offers a theoretically unbreakable form of encryption. The security is based on the fundamental principles of quantum mechanics, making it resistant to traditional cryptographic attacks.
Security Against Eavesdropping:
Quantum cryptography ensures robust security against eavesdropping by possessing the capability to identify any interception efforts. Any endeavor by a third party to measure or manipulate quantum states in the course of communication disrupts the entanglement, serving as a vigilant signal to the communicating parties about the intrusion.
As quantum computers advance, they pose a potential threat to classical cryptographic algorithms. Quantum cryptography also explores the development of quantum-resistant cryptographic algorithms, ensuring data security in a future where quantum computers may break current encryption methods.
Post-Quantum Cryptography pertains to cryptographic methods and strategies crafted to maintain security in the face of quantum computers.

Its objective is to safeguard sensitive information, ensuring confidentiality and security in a future where traditional cryptographic systems might be vulnerable to quantum advancements. Post-quantum cryptography delves into mathematical structures and cryptographic elements considered robust against potential quantum attacks.
Post-Quantum Cryptography encompasses various types of cryptographic algorithms and approaches. Here are some key types:
Lattice-based cryptography relies on the hardness of certain problems associated with mathematical lattices, providing a foundation for creating cryptographic schemes that are believed to be secure against quantum attacks.
Hash-based cryptographic algorithms are based on the security properties of hash functions. These algorithms leverage the difficulty of breaking pre-image resistance in hash functions, making them a candidate for post-quantum cryptographic schemes.
Code-based cryptographic algorithms rely on the difficulty of decoding linear codes. They are considered a promising post-quantum solution because decoding linear codes is believed to be a problem that is hard even for quantum computers.
Multivariate Polynomial Cryptography:
This approach involves the use of systems of multivariate polynomials over finite fields. The security of these systems relies on the difficulty of solving systems of nonlinear equations.
Quantum cryptography, rooted in the principles of quantum mechanics, secures communication channels through applications like Quantum Key Distribution (QKD), where quantum particles such as photons exchange cryptographic keys. The observer effect serves as a built-in alarm system, making any eavesdropping attempts detectable and ensuring the security of key exchanges.
