The Quantum Image Processing (QIP, based on developing along quantum computing and digital image analysis) is an emerging field. Due to the growing needs for image processing with high speed and efficiency in applications including medical imaging, satellite surveillance, autonomous vehicle, and big data analytics, there are limitations of scalability and speed with classical methods. By exploring the very principles on which the modern world operates, from superposition to entanglement, quantum computing provides an altogether transformative perspective on how to process and analyze images exponentially faster. QIP is the topic of this paper and how it might change the way that images are stored, processed, and interpreted; that is, we look at the theoretical foundations and practical considerations of QIP. Quantum representation of images, quantum Fourier transforms, and quantum edge detection are discussed. The challenges to technical and implementable aspects of QIP need not preclude the next generation of high speed computation. The objectives of this research include discovering the potential of QIP, and the weaknesses and future occurrence of the QIP technology.

This paper is an overview of quantum communication and propose the future directions of quantum communication, Quantum communication is a far more efficient technology compared with classical communication greater information storage capacity, higher security provided by quantum key which based on basic quantum mechanics laws and faster transmission speed without the limitation of distance. It is a mainstream of future communication developing direction. This paper depicts the basic architecture of quantum communication from different perspectives such as quantum internet, quantum key distribution and integration of quantum communication with other frontier technology. This gives a brief picture of current development of quantum communication. By integrating previous research, this paper demonstrated several existing challenges in decoherence, scalability of quantum network and verification and certification of information. Then this paper analysis the feasibility of solutions to those problems. Finaly, list the opportunities of quantum communication and its benefits, giving directions of future development like integrate photonic technology and free space quantum communication.
