Quantum Computing: The Challenges Of Quantum Computing

Quantum Computing:

• Introduction:

Quantum computing normal everyday computers I.E classical computers have done a lot and changed everyday life for human beings as a whole and different aspects of our life from leisure to travelling. We talk about how match they have achieved but how about we look at what they are bad at and not been able to achieve. This is where quantum computing comes. But before we can answer that we must first answer the questions.

• What is quantum Computing:

A quantum computer is a computing machine design which user the principles of quantum physics to increase beyond the computational power beyond what is attainable by a traditional computer. Quantum computing harnesses quantum machines phenomena

Super computer sometimes takes so many hours to encrypt, whereas quantum computers can be used for the same purpose in a shorter time period making it harder to decrypt the date and information. Many years from now, quantum computers will become the main aspect of computers security there is a significant concern that quantum computers could be used to invade people's

announced on 24 January general commercial availability of the D-wave 2000Q quantum annealed, with 2000 qubits.

4- Intel develops a 17-qubit chip.

• Physical Realizations:

Algorithms are the concept of computer science. The spectacular promise of quantum computers is to enable new algorithms which render feasible problems requiring exorbitant resources for their solation on a classical computer. These quantum bits will have lifetimes determined by physical parameters such as the cavity quality factor. Which can be made very large by increasing the reflectivity of the cavity walls.

They can be used to execute any algorithm even one running on an apparently much more powerful computer. which render feasible problems requiring exorbitant resources for their solution on a classical computer we must be able to prepare quantum bits in some specified set of initial states, and to measure the final output state of the system and also there is law of Quantum computing called "Moore's law" which it's say Moore's law is a computing term which originated the simplified version of this law states that processer speeds. A quick check among technicians in different computer companies shows that the term is not very popular but the rule is still accepted to break
