QUANTUM COMPUTING: Computing
using quantum effects, especially to solve untractable problems (like
factorization or breaking cryptosystems). See also my computing
page.
QUANTUM CRYPTOGRAPHY: A system
based on quantum- mechanical principles. Eavesdroppers alter the quantum
state of the system and so are detected. Developed by Brassard and Bennett,
only small laboratory demonstrations have been made.
QUASISPECIES: A fuzzy distributions
of genotypes characterizing a population of quickly mutating organisms
or molecules. [Manfred Eigen]
