In today’s time, We are seeing A rapidly emerging technology: Quantum Computing. Now computers have become an important part of our lives. Be it any field, be it education or space science show, computers are being used everywhere and it is not possible to do any work without computers these days. So ever since the computer was made, its size has been getting smaller and its capacity has been increasing. You must have noticed that the chip of your mobile which was of 1 GB in the year 2010, is the same chip of the same size that you are getting today of 1 terabyte. So you can imagine from this how fast technology is progressing.
How is a quantum computing different from a personal computer?
So first of all, let’s talk about your personal computer. Bits are used for calculations in your personal computer, in which data is kept in the form of zero and 1. Binary number or binary number is used in machine language. Machine language is used to write programs. Machine language is written in binary code which has only two digits 0 and 1 because the computer understands only binary signals i.e., 0 and 1. When any software is prepared for a computer, it is converted into machine language and when your processor executes any software, it performs all the processes using this machine language.
Now let’s talk about quantum computer, the smallest unit of any is atom and atom is naturally a micro calculator. Scientists got the idea of this only when they understood that micro calculations can be done naturally from atoms.
How does a quantum computer work?
According to physics, any atom naturally rotates (spin) and the spin it does can either be upwards (↑) or downwards (↓) i.e., up and down. And if we look at it according to digital technology, then everything is kept in the form of 0 and 1, that is, the upward spin of the atom can be 1 and the downward spin can be 0, but if the spin of the atom is measured. So, it can be either up or down (⇅) at the same time, which is why it’s not the same as your traditional computer bit.
Therefore, it is called Qubit which is also called Quantum bits. Qubits are quite different from bits. The information contained in bits can either be in the form of 0 or in the form of 1 but in Qubits The information received can be in both 0 and 1 form at once, which increases the computation speed significantly.
241 million times more powerful than supercomputer
Google has claimed quantum supremacy for 47 years more than supercomputers. Quantum supremacy refers to the ability of a quantum computer to work better than a supercomputer. Google claims that the work that a quantum computer can do in 6.18 seconds can take a supercomputer 47 years to do.
Quantum Computing mission has started in India
Many countries and private companies around the world are engaged in making quantum computers. Quantum mission has also started in India, for this a budget of Rs 8 thousand crore has been kept by the government. Only its prototype has been prepared by most of the companies around the world, because quantum computer is also a big challenge. To keep it cold, a temperature of -270 degrees Celsius is required.
What is the calculation speed of quantum computer?
Quantum computers do not do linear calculations like today’s computers, for example, Amazon company has to send its goods from Delhi to 5 addresses in Mumbai, and the company wants that the distance as well as time should be minimum. Quantum computers will calculate the shortest route to each address to find the answer to this question, but quantum computers will only select the answer, which will save a lot of time if you have a computer with 80 qubits.
What is the difference between supercomputer and quantum computer?
Supercomputers use the binary number system Bit. Quantum computers use neutron and proton-based qubit systems. Supercomputer takes one bit either 0 or 1 at a time. Quantum computer can take both the numbers 0 OR 1 OR (0,1) at once. The calculation speed of supercomputer is less than that of quantum computer. Quantum computers are much more powerful than supercomputers. Supercomputer has no working memory of its own.
Conclusion
As mankind is becoming smarter, it is inventing such things which we cannot even think of today. Have you ever thought that instead of a floppy disk, you will use a small pendrive, in the same way a computer? They were once of the size of an entire house, today apart from being small, their speed has also increased manifold, in the same way, quantum computers will also change the direction and condition of information technology in the future, whether it is artificial intelligence or cloud computing. When quantum computer is used, its benefits will increase manifold.
