Improvement of Quantum Circuits Using H-U-H Sandwich Technique with Diagonal Matrix Implementation

Abstract

Quantum circuits are ideal for most of the modern world problems. They are more efficient and reliable for many computations that are a challenge for classical computers. Beside this they are themselves more complex to deal with and too much costly to build. Cost is the most crucial factor for designing or implementation of any circuit but when it comes to quantum circuits it becomes the most unavoidable part of design technique. The hadamard-unitary sandwich technique has an amazing cost reduction potential in quantum circuits.  In this paper we have discussed about how H-U-H sandwich technique came up with a break through minimizing the circuit complexity and played leading role in cost reduction of quantum circuits by minimizing number of gates used. This method also helps in achieving high computation power and efficiency with more feasibility.
