| How practical quantum computers change our lives |
If you
were living a hundred years ago and you were told that in a hundred years
people will be able to get to moon, and mars, or a small gadget would be able
to connect you to other people from any place around the globe in a single
click, you would call me a mad man, but now scientists are preparing for few
new breakthroughs which would be able to change so many things that we have
today, one of these breakthroughs is practical quantum computers which is
thought to change our lives “for better we hope”, so in these lines we will
define quantum computers, and clarify when would we be able to use it the same
way we use normal computers, and mention the advantages and disadvantages of these
computers.
How practical quantum computers work?
In a
simple way; we could say that quantum computers are the new generation of
computers which use the quantum basics to help storing the data and making the
calculations, as these computers use the quantum superposition theory, this
theory helps to replace the old storing unit “Bit” with a new one called “Qubits”,
these “Qubits” would overcome the normal bit unit because the bit unit depends
only on a true or false answer which represented by 0 or 1, while qubits uses super
positioning to make the answer: true, false or maybe, which is represented by
0,1 or both of them, which provides so many possibilities and therefore larger
capacity for information and faster calculations, so we could say that
practical quantum computer to normal computers are like astronauts to cavemen.
How could practical quantum computers change our lives?
These
computers could change our lives in a huge way, as they have so many advantages
like:
· Help solving the
unsolved equations in few seconds which a normal computer would take hundreds
of years to solve.
· Help improving
the weather prediction programs.
· Help humanity to
discover many new medicines by processing equations with so many variables in a
short time, which was a slow exhausting process using the normal computers.
· Help optimizing
the new projects in so many fields such as the telecommunication field and transportation
field.
· In the astronomy
field we could see a breakthrough after using practical quantum computers to analyze
the huge data.
There
are so many other benefits of using practical quantum computers as the scientist
call these computers “unlimited”, and we hope to find much more advantages of
using them.
Disadvantages of practical quantum computers
We could
say that the disadvantages of practical quantum computers look tiny compared to
their advantages, but still the disadvantages are:
·
This new generation of computers requires much lower
degrees to operate, and this will be hard to provide considering the ability to
make a room temperature that low, or even producing high-efficient coolers will
have much impact on these computers’ price, and would make it difficult to own
one of them.
·
The domestic use of these computers would be almost
the same as the old ones, as they would operate the used programs with the same
speed with no ability to make it faster.
