To gain a computational advantage over traditional computers, Q.C made use of specific physical implementation. The standard set of universal reversible logic gates like CNOT, Toffoli, etc provide elementary basis for Quantum Computing. Reversible circuits are the gates having same no. of inputs/outputs known as its width with 1-to-1 vectors of inputs/outputs mapping. Hence vector input states can be reconstructed uniquely from output states of the vector. Control lines are used in reversible gates to feed its reversible circuits from work bits i.e. ancilla bits. In a combinational reversible circuit, all gates are reversible, and there is no fan-out or feedback. In this paper, we introduce implementation of 4x4 multipurpose logic circuit/gate which can perform multiple functions depending on the control inputs. The architecture we propose was compiled in Xylinx and hence the gating diagram and its truth table was developed. Keywords: Quantum Computer, Reversible Logic Gates, Truth Table 1. QUANTUM COMPUTING computations have been performed during which operation based on quantum Quantum computer is a computation device computations were executed on a small no.
