In
the world of Information Technologies (IT), there is hardly a topic that
generates more interest and debate than quantum computing. The idea of machines
that utilize quantum mechanics to solve complex problems beyond the reach of
even the most powerful supercomputers sounds fantastic. However, it is already
becoming a reality.
Imagine
that a modern supercomputer, for which the execution of specific tasks takes
thousands of years, is replaced by a device capable of solving them in a few
minutes. It is what the developers of quantum systems are striving for.
Although these devices are still in the development stage, their potential
redefines our vision of the future of IT.
How
it all began.
Quantum
phenomena are mysterious and often counterintuitive. How do you explain that a
particle can be in two places simultaneously? Or how does a change in one
particle's state instantly impact another particle on the opposite side of the
universe? These properties—particularly superposition and entanglement—lie at
the bottom of the performance of quantum computers.
The
origins of quantum computing can be traced back to the mid-20th century when
physicists began to explore how the properties of quantum particles could be
used for computing. The first theoretical works, particularly Richard Feynman's
idea of modeling quantum systems, became the starting point for the development
of new technologies.
