註釋A computer is a piece of hardware that aids in the processing of information by carrying out preprogrammed instructions. One definition of an algorithm is "a procedure that is well-defined and has a finite description for realizing an information-processing task." There is always the possibility of converting an information processing job into a physical one. Working with an idealized computer model may be highly beneficial and is often even necessary when developing sophisticated algorithms and protocols for a variety of information processing jobs. Nevertheless, it is essential to keep in mind the connection between computing and physics whenever one is researching the actual constraints imposed by a piece of computer equipment, particularly when doing so for some kind of useful purpose. The idealized computing model fails to account for the fact that actual computing equipment is embedded in a broader and often more complex physical environment than is shown in the model. Quantum information processing refers to the application of what we learn about the physical world from quantum theory to the objective of carrying out activities that were previously regarded to be either impossible or infeasible. This type of processing was thought to be either impossible or infeasible. Because of this, things that were before thought to be impossible or impossible to achieve are now within reach. Quantum computers are defined as any computers that have the capability of processing quantum information. In this book, we investigate how quantum computers can be used to execute specific tasks more quickly than conventional computers can, as well as how they may be used safely even when errors are likely in the work they are performing. In addition, we analyze the benefits that quantum computers have over conventional computers in terms of the ability to resolve certain categories of problems. The next chapters will expand upon the basis provided in this first chapter by presenting more complex subjects in computation theory and quantum physics. This will be done by building upon the foundation laid in this chapter.
