Online Testable Ternary Reversible Circuit

In recent years ternary reversible logic has gained more attention because of its enormous potential in different fields, in particular quantum computing. In order for any future technologies to be reliable they must be testable, thus developing testing techniques in this area is of great importance. In this work we propose a new approach for creating an online testable ternary reversible circuit. To our knowledge this is the first such circuit of its type to be proposed. The proposed testable block can be used to implement almost all of the ternary logic operations and is capable of testing the reversible ternary network in real time (online). The error detection unit is also constructed in a reversible manner, and thus the entire reversible testable block can be used to construct complete reversible circuits.
