A Review on Quantum Circuits: Qubits, Qudits, Reversible Logic Circuits and its Applications

Quantum Computing has already stepped into the world and is also fostering research in many domains. The efficiency and reliability of Quantum efficiency is limited by the Hardware implementation resources existing now. Various domains of qubit implementation have been explored, for coming down to the conclusion, that which is the best implementation of the qubit. Further, the concept of qudits is also been initiated in the research industry and is been explored. In this paper, we explore the various domains of different qubit implementation, shed light on qudits and present the designing of reversible gate which are used for making reversible circuits.
