Post-quantum cryptography refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer.

Industry experts are attempting to develop mathematically based cryptographic algorithms (post-quantum cryptography) that would protect the public-key infrastructure, some predict these algorithms might not be available until the year 2023.

Quantum cryptography, on the other hand, uses the principles of quantum mechanics to send secure messages, and unlike mathematical encryption, is truly un-hackable.

Unlike mathematical encryption, quantum cryptography uses the principles of quantum mechanics to encrypt data and making it virtually unhackable.

# Quantum Cryptography

The sender transmits photons through a filter (or polarizer) which randomly gives them one of four possible polarizations and bit designations: Vertical (One bit), Horizontal (Zero bit), 45 degree right (One bit), or 45 degree left (Zero bit).

The photons travel to a receiver, which uses two beam splitters (horizontal/vertical and diagonal) to “read” the polarization of each photon. The receiver does not know which beam splitter to use for each photon and has to guess which one to use.

Once the stream of photons has been sent, the receiver tells the sender which beam splitter was used for each of the photons in the sequence they were sent, and the sender compares that information with the sequence of polarizers used to send the key. The photons that were read using the wrong beam splitter are discarded, and the resulting sequence of bits becomes the key.
