Quantum computers are capable of solving certain problems exponentially faster than classical computers, which poses a major challenge to modern cryptography. However, researchers are actively developing new cryptographic techniques that are resistant to attacks by quantum computers. These techniques are collectively known as post-quantum cryptography.

Post-quantum cryptography is designed to be resistant to attacks by both classical and quantum computers. One of the main approaches used in post-quantum cryptography is to base the security of the cryptographic system on mathematical problems that are believed to be hard for quantum computers to solve. For example, lattice-based cryptography relies on the difficulty of solving certain types of mathematical problems involving lattices.

Another approach used in post-quantum cryptography is to use cryptographic systems that are based on quantum mechanics. These systems, known as quantum cryptography, use the principles of quantum mechanics to ensure the security of communication channels. Quantum cryptography is not vulnerable to attacks by quantum computers, but it is still susceptible to some types of attacks by classical computers.

Overall, post-quantum cryptography is an active area of research, and many new cryptographic techniques are being developed to protect against potential quantum computer hacks. As a software engineer, it is important to stay up-to-date on the latest developments in post-quantum cryptography to ensure the security of software systems in the future.
