Obstacles of Quantum Error Correction and Decoherence and Impact on Qubit Behavior

The quantum computing theoretically serves as a path to many high-level complex problems, but suffers some profound challenges which become hurdles in its path to a practical scenario. It has deep rooted inexplicable and unsettled challenges like Quantum Error Correction (QEC), qubit instability and issues of quantum decoherence. One of the main obstacles in quantum computing is tenuousness of quantum information processing. The time limit and decoherence problem have been a long-term scientific barrier in the theory of quantum mechanics. The quantum behavior of a quantum computer is influenced and affected by the surroundings creating a ‘race against time’ causing errors in the quantum computations making later unreliable. The error correction requires resource overhead further causing the data processing complexities and so remains as a monumental issue. This paper discusses some major unresolved limitations and deficiencies of quantum computing to eliminate the hurdles, for a need to create a transformative potential technology in the era of quantum computing.
