Scientists all over the world have been working
to create a super computer that can solve
the most complex problems,... using concepts
of quantum physics where more than one reality
or state of being can exist.
The world's first commercial quantum computer
has landed in Seoul today,... to mark the
progress made after decades of research in
the field.
Oh Soo-young has more.
It looks like an golden chandelier, but you're
not seeing shards of glass.
It's a model of the world's first commercial
quantum computer,... on display in the Korean
capital on Tuesday.
Quantum computers are being developed around
the world to process information and solve
problems that are extremely difficult or even
impossible for standard computers.
"Maybe something takes a thousand years or
a million years on a classic computer.
You can do in a few hours or few minutes on
a quantum computers.
We think that will happen on a range of industries.
It could be the creation of brand new materials
household materials, they could be metal alloys
for cars or for aeroplanes.
They could be new drugs for medicines.
Financial services so banks are very interested
in that."
"The IBM Q may have provided a conceptual
turning point, expanding quantum computing
beyond the walls of the lab,... but when it
comes to outperforming a regular computer
on meaningful tasks, or achieving the so-called
“quantum advantage”, most scientists say
we still need more time."
Normal computers store data in binary form,...
as either ones or zeros.
However, quantum computers use a unit called
a qubit, which can exist as a one and a zero
at the same time,... in what's called a state
of "superposition".
As both possibilities exist,... this increases
the amount of data the computer can store
or process,... meaning it can run through
all possible outcomes at once.
However, it's not just the number of qubits
that matter keeping them in a workable state,...
or "coherence time" is one of the biggest
hurdles in quantum computing.
"We need to convert the qubits into effective
cubits.
What is important is the connection between
the qubits, If you have more connection, then
you have higher capacity to handle more complex
problems.
We envision that real practical applications
will be found once machines achieve 100 qubits.
"
Despite the complications,.. researchers and
firms are striving to harness the quantum
advantage,... which could take the AI revolution
and data clouds to a whole new realms.
"Already, the flow of data across countries
is adding more to the global economy than
manufactured goods.
That will also form the basis for society’s
biggest problems like how to better cure cancer,
how to better forecast weather so we can better
save lives."
While quantum computers are unlikely to replace
standard computers for decades, if ever,...
scientists say it's clear a new era of computing
has begun.
