Quantum computing is the system of using standards from quantum mechanics to create powerful computers that will resolve delegate issues very fast than normal classical computers.
Instead of using bit to represent informations quantum computers uses quantum bits or qubits.
There are so many advantage of quantum computing, superposition is one of the best feature of quantum computing a quantum computer can be able to conduct many state of computation simultaneously and this results to exponential speed up on certain algorithm.
Entanglement happens to be another wonderful feature of quantum computing because once qubits entangles they will depend on each other no matter the distance they are and this will help to do proper works and accurate calculation.
More Advantages of quantum computing.
Quantum computing solves most problems like performing some type of optimization, factory large numbers, stimulating quantum system and searching for large database faster than classical computing with the use of quantum mechanics.
Another advantage of quantum computing is that it help to solve some optimisation obstacles that comes in finance, cryptography, drug Discovery, engineering and sometimes logistics.
In logistics travelling salesperson facing some challenges on how to find the shortest route to some cities and how to cover many cities as soon as possible and return back safely without getting lost quantum approximate optimization algorithm (QAOA) helps to tackle the traveling salesperson issue.
In finance portfolio optimisation always searches for how to allocate their assets and get returns without much risk quantum algorithm help to provide faster solution to portfolio optimization or portfolio management.
More to that Quantum Approximate Optimization Algorithm and Quantum Adiabatic Algorithm helps to solve constraints satisfaction challenges.
Quantum computing helps to speed up machine learning and neural training network there by solving optimisation challenges in support vector machines.
When it comes to drugs Discovery quantum computer helps in speeding up drug Discovery process by optimizing molecular structures and stimulating quantum systems.
In logistics quantum computing helps in solving some complex issues like management of inventory, management of resource allocation and optimization of supply chain routes.
Quantum computing helps in cryptography and security
Quantum computing has actually done a whole lot on cryptography and security both in solving cryptographic problem and creating new cryptographic technology for instance Shor's algorithm has the ability to disable the widely used classical cryptography algorithm thereby leaving the security of widely deployed public key schemes behind because they have difficulty in factory large numbers.
Quantum computing uses quantum key distribution to protect key exchange between two parties, this quantum mechanic provide high-security between the two parties because it detects any obstacle or obstruction that comes during quantum communication.
Challenges of quantum computing.
Like every other transformative technology quantum computing faces ethical and societal implications that will need to be resolved it also faces some other challenges.
One of the Ethical and societal challenges that's quantum computer face is privacy and security quantum computing needs a lot of work to be powerful enough for the society to trust or in trust them with personal data government communication and financial transactions but o computing needs to develop what is known as quantum resistant cryptographic techniques for them to achieve this.
Another ethical and societal issue quantum computing faces is data for their ability quantum computing have to breakup traditional encryption this has led to so many questions on how secured storage of data are both past data and future data that will be generated.
Quantum coherence need a steady maintenance for error computation and also to avoid decoherence because what beats are highly susceptible, quantum computing always have a lot of error to be corrected due to some factors like in perfect gates and physical components so is always important to ensure that there is a reliable and accurate computation and this require the last amount of resources.
Scalability happens to be another challenge that occurs in the implementation of quantum computing because most times it is very difficult for quantum system to handle a larger or complex computational issues as resources like quantum gate increases and this makes it more difficult to achieve scalability
Despite the fact that quantum computing has succeeded in solving most computational task there are still some developing computational issues that quantum algorithm has not been able to resolve and this has been a challenge.
For instance quantum algorithm hires quantum oracles that sounds as quantum circuits to specify the input and output of some challenges and this oracle's need to be designed so this designing part is a developing challenge for quantum computing, this also affects quantum parallelism because effectively designing quantum parallelism that will efficiently explore large solution page has always been a challenge a developing challenge at that.
Quantum computing is also facing the issue of public stability and fidelity because if quabit do not remain stable during competition process it may lead to inaccurate results so to ensure high-quality qubits and get precise gate operation has always been a developing challenge.
Building and maintaining quantum hardware has not always been an easy that because it's required a lot of ultra low temperature which has been challenging to quantum computing engineers.
Moreover it has not been easy to maintain a standard and interoperability between quantum hardware and software system.
Conclusion.
Despise all the mention challenges we can set up quantum computing has played a vital or important role in different fields, from material science to drop discovering and cryptography and it's also help to resolve so many optimization challenges or issues.
