Quantum Computing

Quantum computer is an advanced form of computer which is very different from a regular computer as these are used for not personal use but for commercial use. In today's world artificial intelligence is the king and to teach AI we need to first understand how different calculation are taken . To do a complex calculation like probability, estimation, etc can all be done using a quantum computer.

The calculation which cannot be done by regular computer can be done by quantum computers.

Quantum computer manipulates qubits or units of information which are tucked inside the subatomic particle. This makes it possible that at one point in time there can be two states at once.

The 0 positions and the one position are in the same point so it allows us to take two numbers simultaneously and this help in getting more accurate info on the subject and store more information than a personal computer.

Qubits

Everything from e-mail to tweets or iTunes music that you download and the youtube video that you watch are long strings of these binary digits that at different position help the computer to do a particular task at a given time.qubits are typically subatomic particle.

Some companies, such as IBM, Google, and Rigetti Computing, use superconducting circuits cooled to temperatures colder than deep space.

Qubits have some quirky quantum properties that mean a connected group of them can provide way more processing power than the same number of binary bits. One of those properties is known as superposition and another is called entanglement.

Quantum computer is not mainstream at all these are a very large machine of the size of a room and are still in their beta phase where this computer can only do the calculation as that of the personal computers. These are very much unreliable and not Yet powerful at all.

It will have a major impact on chemistry .there are certain kind of reactions that the classical computer is not able to perform and this quantum computer can manipulate the different form of data in such a way that is very difficult for a personal computer to simulate.

The first step is to make these quantum chips. At the same time, we’ve actually made a simulator on a supercomputer. When we run the Intel quantum simulator, it takes something like five trillion transistors to simulate 42 qubits.

Quantum decoherence

One of the greatest challenges is controlling or removing quantum decoherence. This usually means isolating the system from its environment as interactions with the external world cause the system to decohere. However, other sources of decoherence also exist.

As a result, time-consuming tasks may render some quantum algorithms inoperable, as maintaining the state of qubits for a long enough duration will eventually corrupt the superpositions.

But I don’t think it makes much sense to speculate about what most people will be doing with quantum computers in 50 years. It may make more sense to ask when quantum computing will become something that anyone can use from their own home.

The ability of a quantum computer to use qubits has enabled it to break many cryptographic systems in the use today.The power of quantum computers Integer factorization is believed to be computationally infeasible with an ordinary computer for large integers that are the product of only a few prime numbers.

Most of the domain key is made on the difficulty of factoring integers. So these quantum computers can be used to secure and protect Web pages, encrypted email, and many other types of data.
