New quantum algorithm for studying NP-complete problems
Ordinary approach to quantum algorithm is based on quantum Turing machine or quantum circuits. It is known that this approach is not powerful enough to solve NP-complete problems. In this paper we study a new approach to quantum algorithm which is a combination of the ordinary quantum algorithm with a chaotic dynamical system. We consider the satisfiability problem as an example of NP-complete ...
متن کاملA New Quantum Algorithm for NP-complete Problems
An approach to the solution of NP-complete problems based on quantum computing and chaotic dynamics is proposed. We consider the satisfiability problem and argue that the problem, in principle, can be solved in polynomial time if we combine the quantum computer with the chaotic dynamics amplifier based on the logistic map. ∗To be presented at the Third International Conference on “Unconventiona...
متن کاملNP-complete problems and Quantum Search
Consider SAT, the prototypical example of an NP-complete problem. An instance of this problem consists of a Boolean function f (x1, . . . ,xn) = c1 ∧ . . .∧ cm; the SAT problem asks you to determine whether there exists a satisfying assignment—that is, an input (a1, . . . ,an) such that f (a1, . . . ,an) = 1. UNIQUE-SAT is a variant of SAT that poses the same problem with the restriction that f...
متن کاملNew NP-Complete Problems Associated with Lattices
In this paper, we introduce a new decision problem associated with lattices, named the Exact Length Vector Problem (ELVP), and prove the NP-completeness of ELVP in the ∞ norm. Moreover, we define two variants of ELVP. The one is a binary variant of ELVP, named the Binary Exact Length Vector Problem (BELVP), and is shown to be NPcomplete in any p norm (1 ≤ p ≤ ∞). The other is a nonnegative vari...
متن کاملComplete Problems for Monotone NP
We show that the problem of deciding whether a digraph has a Hamiltonian path between two specified vertices and the problem of deciding whether a given graph has a cubic subgraph are complete for monotone NP via monotone projection translations. We also show that the problem of deciding whether a uniquely partially orderable (resp. comparability) graph has a cubic subgraph is complete for NP v...
