Quantum Computing

Moore’s Law

As Moore's Law states, the number of transistors on a microprocessor continues to double every 18 months.

 The world is moving fast and the computing requirements are going exponential. How to meet this demand, if go more and more transistors per inch surely we will hit a limit, isn’t it? How to meet this demand? Scientists and physicists across the world are working on this problem, some brilliant scientists and physicists thought why can’t we use the phenomenon of quantum mechanics to solve this growing needs of human beings and take them to the next level, from that they derived a new branch of study called quantum computing. They used the concepts like superposition, quantum entanglement etc.

 What is the difference between legacy computing and Quantum computing?

In legacy computing information is represented as binary streams of 0 and 1, these 0 and 1 can be on or off a transistor voltage level like +5v or ground. In quantum computing there are 3 states called 0,1 and 0 and 1 together these information is called as qbits(quantum bits), the benefit of this is that in conventional computing for 3 bits it takes 8 cpu cycles or sequence to get all the 8 possible combinations, where as in QC all these can be obtained in one time. The benefit of this is many problems which requires years to solve can be done in matter of seconds for credit card information is encrypted in 256bit key now in the conventional computing requires years to decode it can be decoded in seconds. The agency can snoop in to any communication and get what they want.

 Quantum Superposition

 In the quantum world superposition can mean something different entirely. At the quantum scale, particles can also be thought of as waves. Particles can exist in different states, for example they can be in different positions, have different energies or be moving at different speeds. But because quantum mechanics is weird, instead of thinking about a particle being in one state or changing between a variety of states, particles are thought of as existing across all the possible states at the same time. It’s a bit like lots of waves overlapping each other. This situation is known as a superposition of states. If you’re thinking in terms of particles, it means a particle can be in two places at once. This doesn’t make intuitive sense but it’s one of the weird realities of quantum physics.

Quantum Entanglement

Albert Einstein told about these phenomenon “spooky action at a distance”.

Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently of the others, even when the particles are separated by a large distance – instead, a quantum state must be described for the system as a whole.

It is like if you change the state of a particle in earth immediately that change is taken care if I measure the entangled particle state in Andromeda. The main benefit is that you don’t need equipment’s or transporters to do this, but how this happen puzzles the beautiful minds of the world.  

                     World’s First Quantum Computer

 D-WAVE proclaims that they build the first quantum computer and they sold it for 15 million and 25 million USD. They claim they build these computers with the help of parallel universe as per their CTO’s words. They take the resource from other universe.

 Use Case

With the help quantum computer and machine learning what is impossible now will be a reality. A person can be profiled based on the emotion, when a person enters the public space, it can check different face pattern to find whether he is a criminal disguised. Individuals need not invest on huge computing all of the world can be connected to a single entity, all can be monitored and helped. This will take the human beings to the next level. Whether this will be bringing Armageddon or Alien invasion for stealing their resources that the time will tell us. Hope for the best.
