2-tape 1-way Quantum Finite State Automata

- Computer Science, PhysicsArXiv
- 2016

It is established that 2-tape 1-way quantum finite state automaton (2T1QFA(2)) can accept all regular languages and it is shown that a language which cannot be accepted by any multi-head deterministic finite automaton can be acceptedBy exploiting the superposition property of quantum automata.

One-way quantum finite automata together with classical states

- Computer ScienceArXiv

A new computing model of 1QFA, namely, one-way quantum finite automata together with classical states (1QFAC for short), is developed, a component of classical states is added, and the choice of unitary evolution of quantum states at each step is closely related to the current classical state.

It is proved that two-way probabilistic and quantum finite automata (2PFAs and 2QFAs) can be considerably more concise than both their one-way versions, and two- way nondeterministic finite automaton (2NFAs), and it is shown that 2ZFAs with mixed states can support highly efficient probability amplification.

It has been proved that a language which cannot be recognizing by any one-way and multi-letter quantum finite automata can be recognized by two-way quantum finite Automata with two heads and it has been investigated that quantum variant of two- way deterministic multihead finite automaton takes less number of heads to recognize a language containing of all words whose length is a prime number.

Two-way Quantum One-counter Automata

It is proved that 2Q1CAs are at least as powerful as classical two-way deterministic one-counter automata (2D1C as), that is, every language L recognizable by 2D1 CAs is recognized by 2Q 1CAs with no error.

This paper characterize the measure-once model when it is restricted to accepting with bounded error and show that, without that restriction, it can solve the word problem over the free group and shows that piecewise testable sets can be accepted with boundederror by a measure-many quantum finite automaton, introducing new construction techniques for quantum automata in the process.
