In this chapter, we discuss about how quantum computers are different from classical computers and their advantages over classical computers. We also discuss some hypotheses regarding how a quantum computer works.
Computational capabilities are reaching their limits with the current technology. Quantum computing is the answer to this limitation. It has unraveled new possibilities of solving the unsolvable and computationally hard problems within a feasible time frame. In this chapter, the authors have discussed the basics of quantum computing, which include the need for quantum computers and how it internally works without getting into too much mathematics for an introductory understanding. The authors have also discussed different technologies in which the scientific communities and industries are working to make these computers feasibly work and the different programming techniques and tools available to implement the algorithms in these computers and the testbeds available to common people for testing the feasibilities of their programs.
This chapter covers quantum consensus. Before we explain what quantum consensus is, a basic introduction to quantum computing and its advantages is given to build an understanding about how quantum computer works. Moreover, topics like quantum networks, quantum Internet, quantum cryptography, and quantum blockchains are also covered. Then we discuss quantum consensus and explain what it is, how quantum computing impacts classical consensus in classical and quantum networks, and how quantum computing can enhance existing distributed consensus protocols. We survey what has been done so far in the research community and some open research problems.
Engineers working in the biomedical field have a wide range of responsibilities, such as helping to introduce a new medical imaging technology or to create assiduous devices to assist someone with a disability. Many people consider what exactly constitutes biomedical engineering reasonably clear. Still, there are many differences of opinion regarding this field that can be traced to differences concerning the definition of the field. This chapter aims to provide an understanding of the ground of biomedical engineering and its relevance in quantum computing. The authors are discussing various areas of biomedical engineering where research is constantly happening. With the combination of quantum computing, biology, engineering, and computer science, researchers always strive to be the best.
Since last years, computers reduce the human efforts and give improvement in its performance day by day.Quantum computers are those computers who perform computing which is based on the phenomenon called Quantum Mechanics.It is a fusion of classical computing which we were using now days, physics and mathematics.And the computing they performed by integrating these fields is termed as Quantum Computing.Quantum computers perform their computing on the basis of the microscopic particles like ions, photons, electrons, protons, neutrons etc which ultimately give exponentially high computation power and other advantages too like less consumption of electricity which we will discuss in the same paper in brief over the classical computers, which we were using till day.In this paper we will briefly explain the quantum computers, its history, its properties in which its computing is based upon, its advantages& disadvantages, its limitation, its real world application, the difference between classical computers and Quantum computers and the challenges it faced and at last we conclude it with its future scope.
