What Is a QBOM (Quantum Bill of Materials)?
QBOM stands for Quantum Bill of Materials, but the term is used inconsistently across the industry. Some mean an inventory of quantum computing components; others mean a cryptographic inventory viewed through quantum risk. This reference sorts out the terminology and…

Quantum-Inspired Encryption
"Quantum-inspired" is a legitimate term in optimization and machine learning. In a security and encryption context, it is a red flag. Classical algorithms do not inherit quantum security properties by borrowing quantum vocabulary.

What Is Trust Now, Forge Later (TNFL)?
Trust Now, Forge Later is the quantum threat to digital signatures. While Harvest Now, Decrypt Later targets confidentiality, TNFL targets trust — and the consequences may be more systemic. I coined the concept in 2018, and the research since has…

Quantum Blockchain
Adding a quantum random number generator or a post-quantum signature to a classical blockchain does not make it a "quantum blockchain." The prefix implies a physics transformation that has not occurred.

What Is PQC Migration?
PQC migration is the process of transitioning an organization's cryptographic infrastructure from classical algorithms to post-quantum standards. NIST estimates three to five years for a large agency. Most enterprises should expect the upper end. This reference explains what the migration…

Quantum Financial System (QFS)
The "Quantum Financial System" is not a technology. It is a conspiracy theory rooted in the NESARA/GESARA movement that has been weaponized to sell fraudulent cryptocurrency tokens, fake "activation fees," and pump-and-dump schemes.

What Is Quantum Key Distribution (QKD)?
Quantum key distribution uses the laws of physics to share encryption keys in a way that makes eavesdropping detectable. The security guarantee is real, but so are the practical limitations. This reference explains the technology, the protocols, and the ongoing…

What Is Quantum Error Correction (QEC)?
Quantum error correction is how quantum computers fight their own fragility. Without it, no quantum computer can run the long computations needed to break cryptography. For security leaders, QEC progress is the single most important indicator of how fast the…

Unhackable Quantum Encryption
QKD's information-theoretic security is real physics. "Unhackable" is not. Detector blinding, Trojan horse, and side-channel attacks have been demonstrated against commercial QKD systems. The protocol is secure; the hardware is not immune.

Unconditionally Secure
"Unconditionally secure" is a real term with a precise mathematical meaning. In product marketing, the qualifying assumptions are stripped away, leaving a claim of absolute security that the physics never intended.

Perfect Secrecy
Shannon's 1949 theorem defines perfect secrecy precisely: the key must be at least as long as the message and used only once. Any product claiming perfect secrecy while violating either condition is contradicting a mathematical proof.

Information-Theoretic Security
Information-theoretic security means security that holds regardless of an attacker's computational power. In marketing, the term is presented as an absolute, implementation-independent guarantee. It is not. The guarantee applies to a model, not to a box.

Quantum Encryption / Quantum Cryptography
"Quantum encryption" and "quantum cryptography" technically refer to QKD and related protocols. In marketing, they are applied to everything from NIST post-quantum algorithms to classical software with no quantum hardware. This guide disambiguates.

Quantum-Enhanced
"Quantum-enhanced" is applied to everything from phones with real QRNG chips to classical software with no quantum hardware. The term has no standard definition, which makes it a vehicle for claims that range from overstated to fabricated.

Quantum-Safe vs Quantum-Resistant vs Post-Quantum
"Quantum-safe," "quantum-resistant," and "post-quantum" are used interchangeably by vendors. Standards bodies have spent years trying to fix this. The differences matter for procurement, compliance, and whether a product does what you think it does.
