QUIC Transport
UDP‑based transport used in HTTP/3 and libp2p that offers low latency, multiplexing, and better congestion control.
Quantum Annealing
Heuristic quantum technique for finding low‑energy solutions to optimization problems, typically via annealers.
QAOA
Quantum Approximate Optimization Algorithm, hybrid method for solving combinatorial optimization problems.
Quantum‑Safe Cryptography
Also called post‑quantum, schemes designed to resist quantum attacks, for example lattice‑based signatures and KEMs.
Quantum Random Number Generator (QRNG)
Entropy source that uses quantum phenomena to produce truly random bits, useful for cryptography.
Quantum Key Distribution (QKD)
Technique for establishing shared keys with security based on quantum physics, eavesdropping is detectable.
Quantum Supremacy
Controversial milestone where a quantum device performs a specific task infeasible for any classical computer.
Quantum Advantage
When a quantum algorithm or device performs a task faster or cheaper than classical methods.
QUBO (Quadratic Unconstrained Binary Optimization)
Optimization formulation targeted by quantum annealers and used to encode combinatorial problems.
Q‑Former
Lightweight transformer module that learns query tokens to extract useful features from vision encoders for multimodal models.
