​Quantum cryptographer is a profession that develops and implements the cryptographic techniques based on the principles of quantum physics. Quantum cryptographer can provide secure and efficient communication and computation, by using the properties of quantum particles, such as superposition, entanglement, and no-cloning. Quantum cryptographer can also protect the information and data from the threats and attacks of quantum computers, which can break the conventional cryptography. Quantum cryptographer is a cutting-edge and important profession that can enhance the privacy and security of the digital world.
