On Coverings of Products of Uninitialized Sequential Quantum Machines
The concept of sequential quantum machine (SQM) was firstly introduced by Gudder. Qiu further investigated some properties of SQMs and introduced the concept of quantum sequential machine (QSM) which was an equivalent version of SQM. A uninitialized sequential quantum machine (USQM) is a sequential quantum machine which has no initialized state. The main purpose of this paper is to investigate three coverings of products of USQMs: covering, probability covering and weak probability covering. More specifically, we firstly introduce the concepts of products of USQMs and study properties of these products. Secondly, we introduce the concept of covering of USQMs, and study covering properties of products of USQMs. Finally, we introduce the concepts of probability cove- ring and weak probability covering of USQMs, and study properties of these coverings of products.
