The goal is to replace vulnerable public-key algorithms like RSA and ECC with new algorithms that provide equivalent functionality – encryption, digital signatures, key exchange – while remaining secure against quantum attacks. While post-quantum cryptography uses mathematics to resist quantum attacks, quantum key distribution (QKD) takes a fundamentally different approach – using the laws of quantum mechanics to detect eavesdropping and distribute encryption keys with information-theoretic security. **Cryptographic transitions take decades:** Even with standardized algorithms available today, migrating global infrastructure to post-quantum cryptography will require 10-20 years of coordinated effort. The quantum threat refers to the ability of sufficiently powerful quantum computers to break widely used encryption systems including RSA, elliptic curve cryptography (ECC), and Diffie-Hellman key exchange. Unlike quantum cryptography (which uses quantum mechanics for security), post-quantum algorithms rely on mathematical problems believed to be hard even for quantum computers, such as lattice problems, hash function security, and code-based cryptography.

**Transitioning to quantum-safe cryptographic solutions is no longer a future concern—it is an urgent necessity.** Governments and regulatory bodies are already pushing for the adoption of post-quantum encryption standards to ensure long-term data protection. Classical cryptography has long been the foundation of secure communications, but **the rise of quantum computing threatens to break its most widely used encryption methods**. Quantum computing threatens the security of current cryptographic systems, making quantum-safe cryptography essential. Unlike traditional encryption, which depends on integer factorization or discrete logarithms, **quantum-safe algorithms rely on mathematical problems that remain infeasible for even large-scale quantum computers.** This ensures long-term data protection as quantum technology advances. Cyber threats evolve rapidly, requiring **regular security patches, algorithm updates, and vulnerability assessments.** Staying vigilant ensures encryption remains resilient against both classical and quantum-based attacks, preserving long-term data integrity. Hybrid encryption combines classical cryptography with quantum-resistant algorithms, ensuring security during the transition to post-quantum encryption.

# Post-quantum Cryptography (PQC): New Algorithms for a New Era. by Rambus Press Leave a Comment. [Updated April 14, 2025] Post-Quantum Cryptography (PQC), also known as Quantum Safe Cryptography (QSC), refers to cryptographic algorithms designed to withstand attacks by quantum computers. Leveraging Shor’s algorithm, quantum computers will be capable of reducing the security of discrete logarithm-based schemes like Elliptic Curve Cryptography (ECC) and factorization-based schemes like RSA (Rivest-Shamir-Adleman) so much that no reasonable key size would suffice to keep data secure. Post-Quantum Cryptography (PQC) refers to these cryptographic algorithms designed to withstand attacks by quantum computers. Rambus Quantum Safe IP solutions offer a hardware-level security solution to protect data and hardware against quantum computer attacks using NIST and CNSA selected algorithms. For many years, Rambus has been a leading voice in the PQC movement and now offers a portfolio of Quantum Safe IP solutions designed to offer hardware-level security using NIST and CNSA selected algorithms.

# What is quantum cryptography? ## What is quantum cryptography? Discover emerging research in AI, quantum, hybrid cloud, and more from IBM’s experts with the monthly Future Forward newsletter. Quantum cryptography might be our only recourse for securing private data. ### Quantum Cryptography: The Future of Data Security Starts Now. Learn how IBM Z uses advanced quantum-safe cryptography to protect your data from emerging quantum threats. According to the National Institute of Standards and Technology (NIST), the goal of post-quantum cryptography (PQC, also called quantum-resistant or quantum-safe) is to “develop cryptographic systems that are secure against both quantum and classical computers. Not to be confused with quantum cryptography, which relies on the natural laws of physics to produce secure cryptosystems, post-quantum cryptographic algorithms use different types of cryptography to create quantum-proof security. Quantum-safe security for IBM Z uses cryptographic methods to protect data from quantum computer threats. Bringing useful quantum computing to the world through Qiskit Runtime and IBM Quantum Safe.

In quantum cryptography, data is converted to bits of 0s and 1s, and then transferred using polarized photons. The technicalities of such a transfer are similar to the original process described, where Alice sends polarized photons to Bob, who measures them using randomly selected states. After the keys are exchanged, there is very little concern that someone would be able to decode the data without these keys, since they are different every time and are always generated randomly, or at least become random after about half the bits are discarded to match the polarization states measured by Alice and Bob, and after the error-correcting algorithms. This act will end the quantum relationship of the two members of the pair, which is very easy to detect by Alice and Bob, and impossible to reverse for Eve. Without revealing the specific results of their measurements, the sender and the receiver can talk publicly and see where intervention has taken place.
