For some time from the famous quantum physicist Richard Feynman, the scientists visualize the birth of the quantum computer. Not only it would be more powerful than the best present computer. It would also be capable of incorporating algorithms which can perform operations in a way that has not been achieved before through all past computing.
Although the race is still on to create the premier quantum computer, at Kavli Foundation of Nanoscience, scientists go deep into building the first of this kind. Two of the quantum computer obvious capabilities consist of
- the power to search through raw data being at least 100,000 times and could reach 1,000,000 times higher than the most powerful computer ever built
- the capacity to break into any algorithm, including the encryptions because it deals with unimaginable quantity of data
The scientists are looking into the quantum computers’ problem solving, the challenges to complete the creation of such extraordinary piece of equipment and at how long it would pass until we have the world’s first quantum computer.
Problem Solving Performed by Quantum Computers
In theory, even the most powerful computers at this moment cannot accomplish solving problems as quantum computers can. This is due to the fact that quantum algorithms and quantum bits or qubits allow entanglement, processing in multiple places “at the same time” while also computing dynamically towards the final outcome. Operationally, they can perform at the same time a “jump” from one category to another while looking for the best solution without endangering the final result because it calculates simultaneously the results and the possibilities of their occurrences.
The Challenges of Creation the Quantum Computers
Due to quantum properties of atomic particles in this case qubits, they lose part of their identity and act in correlation with adjacent qubits that they find at that moment around them and which can change at other moment or at another occurrence, for instance, the implication of another element in this whole “action”. Experiments have been generated using a small number of qubits and testing is being performed still using classical computers. Increasing the number of qubits, the algorithms gain in power more than exponentially and thus results are currently difficult to measure, and overwhelmingly they cannot be measured with current classical computers.
