FAQs
What's the difference between post-quantum cryptography and quantum key distribution?
Post-quantum cryptography (PQC) uses classical algorithms to protect against quantum attacks. It is implemented in software, is currently available, and can be utilized in conjunction with current systems. Quantum key distribution (QKD) creates keys with unbreakable, theoretically, encryption by using principles from quantum mechanics. However, this requires new quantum hardware and a quantum-optimized fiber optic network.
Today, most jobs in quantum cryptography focus on implementing PC, as this is what most organizations are using. In contrast, QKD positions are primarily for research at universities and niche companies.
Can I transition from cybersecurity to quantum cryptography?
Yes, cybersecurity professionals are well-positioned to transition into quantum cryptography. Your understanding of encryption, network security, and threat modeling transfers directly. Focus on learning NIST-approved post-quantum algorithms like CRYSTALS-Kyber and CRYSTALS-Dilithium, study lattice-based and hash-based cryptography, and practice implementing quantum-resistant solutions.
Many organizations need people who understand both classical security and quantum threats. Online courses, certifications, and hands-on projects can bridge the knowledge gap without requiring a complete career restart.
Do I need a PhD for quantum cryptography jobs?
Not for most roles. Engineering and implementation jobs usually require a bachelor’s or master’s degree in computer science, mathematics, or cybersecurity. These positions focus on implementing post-quantum algorithms that have been approved by NIST into current systems. Research roles that focus on developing new algorithms with quantum resistance often require a PhD. Both levels are hired by the government and defense contracting companies.
Cybersecurity professionals can move into quantum cryptography positions by learning the post-quantum standards, without the need for a physics background or advanced degree. Learn to get Quantum jobs without PhD here.
What programming languages are needed for quantum cryptography jobs?
Python is a programming language commonly used in quantum cryptography to implement and test post-quantum algorithms. C and C++ are used in embedded systems and in cryptography implementations where performance is critical. Rust is gaining popularity for writing secure libraries in cryptography. Familiarity with certain libraries is important. They include OpenSSL, libsodium, and the post-quantum libraries by NIST. Knowing quantum frameworks such as Qiskit is a plus if you wish to work in quantum key distribution. Most positions focus more on the candidate's knowledge of cryptography and the ability to implement algorithms than on the programming languages they know.
What are NIST-approved post-quantum cryptography algorithms?
NIST approved three post-quantum algorithms in 2024: ML-KEM (formerly CRYSTALS-Kyber) for encryption, ML-DSA (formerly CRYSTALS-Dilithium) for digital signatures, and SLH-DSA (formerly SPHINCS+) as a backup signature scheme. These algorithms rely on math problems that quantum computers cannot easily solve. Organizations are adopting them to guard against future quantum threats. Quantum cryptography professionals implement, test, and deploy these algorithms across systems, networks, and applications.
How do I get started in quantum cryptography with no experience?
Learn the fundamentals of classical cryptography by doing online courses on platforms such as Coursera, edX, and Cybrary. Check NIST’s freely available post-quantum cryptography standards and documentation. Use the open-source libraries from NIST and PQShield to implement the algorithms. Create and present projects that showcase the use of quantum-resistant encryption in real-world scenarios.
If you wish to be recognized in the field of cybersecurity, you can earn certification by passing the CISSP and Security+ exams. Participate in community projects that are open and available to the public. Start applying for positions like security analyst and cryptography engineer via niche job boards such as Quantum Jobs List or Quantum Jobs USA, which are easy to get and provide education for quantum training.
