Current Challenge and Limitations in Quantum Computation

Abstract

This paper reviews various engineering hurdles facing the field of quantum computing. Specifically, problems related to decoherence, state preparation, error correction, and implement ability of gates are considered. Computer computation is very advanced computers used in recent days for various applications, including cryptography, optimization problems, financial modelling, route and traffic optimization, manufacturing drug, chemical research, batteries, simulation of quantum systems, and even machine learning. In a quantum computer, two qubits can also represent the exact same four states (00,01,10 or 11). It’s an exciting field with lots of potential. But it faces lots of challenges and problems like maintaining qubits, interaction with the environment can cause decoherence. However, the adventure to harness the enormous power of quantum computer systems is packed with challenges and boundaries. In this discussion, we can embark on an exploration of the current boundaries that researchers and engineers face within the world of quantum computing, losing mild on the complexities and constraints that ought to be overcome to fully free up its ability. Reacher’s are working on error correction techniques to address this issue and make quantum computations more reliable. It’s fascinating area of ongoing research.
