THE AGE OF QUANTUM
COMPUTING IS UPON US

Science has been engaged in a
very tough race with the tech-
nology and time. Over the past century,
there have been tremendous developments such as the first electronic programmable computer ENIAC, the first
integrated circuit computer, and the first
microprocessor computer. As Moore’s Law
states, the number of transistors on a
microprocessor continues to double in
every 18 months. Between 2020 and 2030
transistors in microprocessors will move
to atomic scales. The atomic realm opens
up powerful new possibilities in computing. This is where the quantum computers
step in.

quantum level. A classical computer works
on long strings of bits such as 011010101
etc. Whatever task you perform on it, the
computer translates the task into a string
of 0s and 1s, then processes algorithms
and provides the result again in 0s and
1s. On other hand, Quantum computers
are not limited to two states and they
use quantum bits knows as ‘qubits’. Qubits
represent atoms, ions, photons or electrons. For example, it is a particle which
can have two types of different properties simultaneously (the particle can be
in both one place and another place at
the same time). Here it uses the physics
