  The recent development of quantum computing, which uses entanglement,
superposition, and other quantum fundamental concepts, can provide substantial
processing advantages over traditional computing. These quantum features help
solve many complex problems that cannot be solved with conventional computing
methods. These problems include modeling quantum mechanics, logistics,
chemical-based advances, drug design, statistical science, sustainable energy,
banking, reliable communication, and quantum chemical engineering. The last few
years have witnessed remarkable advancements in quantum software and algorithm
creation and quantum hardware research, which has significantly advanced the
prospect of realizing quantum computers. It would be helpful to have
comprehensive literature research on this area to grasp the current status and
find outstanding problems that require considerable attention from the research
community working in the quantum computing industry. To better understand
quantum computing, this paper examines the foundations and vision based on
current research in this area. We discuss cutting-edge developments in quantum
computer hardware advancement and subsequent advances in quantum cryptography,
quantum software, and high-scalability quantum computers. Many potential
challenges and exciting new trends for quantum technology research and
development are highlighted in this paper for a broader debate.
