Quantum Computing is one of the rising technologies which will shape the future and advancement in the growing world. What is quantum computing and what is the hype all about? Let us get into the foundation and applications of Quantum computing.
Firstly, classical computers are limited to computational powers. From years together the computation is completely based on the basics of binary technique. The language of 0’s and 1’s let you work on the logic gates but limit you with two states.
For any problem to be computed there can be either a yes or no as a solution. The binary computation is based on these states. If the answer is yes then the value is 1 and if the answer is no then the value is 0.
The world is for exploration of endless possibilities and quantum mechanics is one of them for growing technology. Instead of binary states as that of classical computers, quantum computers contain qubits state. Here, the value can be 1, 0 or both.
As per an informative blog by ZDNet, we came across how quantum computing actually started and why there was a need. During 1981, Prof. Richard Feynman the father of Quantum Electrodynamics stated –
“The only way to build a successful simulation of the physical world at the quantum level would be with a machine that obeyed the laws of quantum mechanics.”
It was then when the world realized that classical computers can only generate probability tables and other tokens. Techspot perfectly explains why quantum computing matters?

Explaining what is Quantum Computing using Examples.
Quantum mechanics believe in looking into the matter before the conclusion. Consider the simple example from quantum mechanics widely used to explain this concept. Schrodinger’s cat is the best example to explain the quantum basics.
When this cat is placed in a box with a cyanide capsule, what are the chances that it will break the capsule, consume it and die? The cat may or may not have consumed the capsule and this can be known by opening the box. This is a very simple and proper example of quantum.

To know the state of computation it is necessary to get into the box. There can be an equal of 50% chances of any computation to be true or false in terms of probability. Now, the extraction of quantum mechanics into the computer world will advance the computations. How exactly?
Flash Applications and Advancement using Quantum Computers –
We know that encryption is totally based on the sharing of secret keys and information through a secure channel. No matter what kind of security standards we use, it is possible to break those encryption mechanisms and steal the data. In fact, the most secure AES – RSA encryption is cracked using Quantum computers.
The present encryption security can be broken but can also be improvised to a greater extent using the same quantum computers.
We know that qubits are either 0,1 or both in nature. When the information is combined using quantum computing, no human can be able to unwind it while transmission.
This is because we exactly don’t know what and how much of the information is being fused together. The original information can be retrieved using the quantum computer. This won’t allow any kind of breach while transmission.
The information retrieval will be close to around 95-97% and the loss is due to system errors or computation error as per the research. The security level in the future will change the way of information exchange in all the domains.
Reverse Time – Time Travel – What is Quantum computing behind this?
The concepts of quantum computing are yielding a lot of unexpected results. No doubt we know that time exists but what if you can get back in time and reverse a few moments of your life and world.
Not so impossible, Quantum scientists have already successfully yielded a noticeable result. As per a report by PhysOrg –
“Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past.”
The complete scientific report of this experiment Arrow on Time and its reversal on IBM Quantum computer” can be accessed here in pdf format for free.
The whole of the experiment is performed in four stages and instead of electrons, superconducting qubits are focused. The four stages are order, degradation, time reversal, and regeneration.

The researchers and Scientists were successful for 85% of the time the experiment resulted. 85% of the success rate is only for returning back of two qubits. Whereas when three qubits are involved there are only 50% of chances. The error rate of 50% is due to the imperfections of a quantum computer at the present stage of development.
Factors that affect the nature of qubits – why and what is quantum computing in a cold environment?
As per Scientific American, the qubits eventually stop spinning and fall into a particular state. The goal for working on quantum bits or qubits is to keep them spinning for a longer time.
What would happen if a coin is spinning on the table and the table is shaking? The coin would settle faster. The same is with qubits. Certain factors such as noise, temperature, electrical fluctuation or vibration may cause settling of qubits faster.
To avoid this, qubits are operated in cold environments such as a dilution refrigerator said Larry Greenemeier.
Quantum Computers are the future of technology we are imagining. The ease of computational work and mesmerizing results will leave us all in shock. No doubt these are still in experimentation but the results obtained for now are top-notch worth. There is a race between IT companies to build the first Quantum Computer whereas IBM claims that they built a lot of quantum processing units.
