Google has
recently claims to have most developed and advanced Quantum Computer, which for
the first time achieved 'quantum supremacy'. That is, Google has surpassed all
conventional computers in terms of computing calculations or performance.
Recently the BBC published news release regarding this. Research articles have
also been published in the ‘Nature’ journal.
What is
Quantum Computer:
A Quantum
Computer can solve many complex problems of quantum mechanism easily. In order
to solve the same problem, a super computer takes hundreds of thousands of
years. This is called quantum supremacy. When an organization or a country will
be able solve such complex problems in a very short time using quantum
computers, it will be said that they have achieved quantum supremacy.
Google has
made a sycamore quantum processor and this Google-made quantum processor is
capable of completing a specific task within 200 seconds while it will take thousand
years to complete the same task using world's best supercomputer. Researchers
and engineers have been trying to build quantum computers for decades and they
have announced that such a computer will be far ahead of the speed.
In the
binary system, the numbers are only one and two (1 and 2). With this binary
majority, all kinds of work are done by the present computer system. However 0
and 1 cannot be represented at the same time. Quantum computers are far ahead in
this step compared to traditional computers.
Google has
claimed that a quantum computer can do the work that is not possible using a
conventional computer. Researchers compared this invention to the discovery of
the first aircraft of the Wilbur Wright brothers in 1903. This is the beginning
of fantasy. However, it will take more time to get the full benefits from this
computer. Google's quantum computer information leaked last month. It claims
that Google has already created a quantum computer.
Power of
Quantum Computer:
Quantum
computers have been a widely discussed term in the technology world for many
years. It is said that anyone who can reach this computer will be the
controller of the whole world.
The special
chip called 'Sycamore' consists of a two-dimensional array of 54 transmon
qubits (the basic unit of quantum computers), where each qubit is tunably
coupled to four nearest neighbors, in a rectangular lattice. Qubits can perform
many times more than traditional computer bits.
Advantages
of Quantum Computer:
Quantum
computers have many advantages. It does not solve many mathematical problems.
According to scientists, quantum computers will be able to solve the problems
that traditional computers have in order to solve very complex problems. As a
result, quantum computers can revolutionize everywhere - from pharmaceuticals
to oil industries.
Particularly
complex mathematical problems in physics and chemistry can be solved quickly.
New drugs will be invented using Quantum Computer. Commercial algorithms of
financial institutions can be further improved. Even the early forms of
artificial intelligence that scientists are working can be improved larger
scale.
Disadvantages
of Quantum Computer:
There are
risks. If an advanced quantum computer created, all the security of the current
Internet of Things could be collapse like a house of playing cards. British
famous newspaper The Economist says quantum computers will be able to do
whatever they want in any organization or company. The personal information of
billions of Internet users across the world can be taken into their own memory.
The government database can be hacked. Undue control can be imposed in the
banking system. State defense system can be turned off if desired. Considering
these aspects, many do not even hesitate to call it a "terrible"
computer.
Google
Says:
Google AI Quantum is advancing quantum computing by developing quantum processors and novel quantum algorithms to help researchers and developers solve near-term problems both theoretical and practical. We think quantum computing will help us develop the innovations of tomorrow, including AI. That’s why we’re committed to building dedicated quantum hardware and software today. Quantum computing is a new paradigm that will play a big role in accelerating tasks for AI. We want to offer researchers and developers access to open source frameworks and computing power that can operate beyond classical capabilities.
