Searching an Unsorted Database in Quantum Computers and Duality Quantum Computers
Gui Lu Long · 2009
Quantum computers exploits quantum entanglement and provides more computing power. Duality quantum computer is a new type of quantum computer that exploits the particle wave duality of quantum mechanics. In a duality computer, the computing gates need not be unitary. This provides more flexibility and familiarity to computer scientists. Here we use the unsorted database search problem as an example to show how to construct search algorithms in quantum computer and duality quantum computers.
