now countries around the world are
racing to develop a supercomputer based
on quantum physics and South Korean
researchers are really on the cutting
edge of developing innovative ways to
turn this transformational tech from
theory as it currently is to reality Oh
Sooyoung with more South Korean
researchers are working on the building
blocks of supercomputing networks that
are hundreds of thousands of times
faster and more secure than present-day
technology quantum computing researchers
at Korea Institute of Science and
Technology have develop ways to use
diamond structures to generate qubits
normal computer store and send data in
binary form as either ones or zeros
however quantum computers use qubits
which can exist as a 1 and a 0 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 as
they're largely volatile keeping them
isolated and in a workable state is one
of the biggest hurdles in quantum
computing we use spin qubits to develop
our system the advantage of using
nitrogen vacancy color centers in
diamonds to make qubits allows them to
work better at room temperature and
there is also good connectivity with
photons we can also incorporate
semiconductor processes to produce
qubits scientists around the world are
working to obtain the quantum advantage
or reached a point where quantum
computers can significantly be
traditional computers at solving complex
problems most expect this would require
at least 5200 stable qubits quantum
cryptography is another promising field
being the closest commercial application
of quantum technology from using secured
Wi-Fi to controlling power grids
encrypted networks are vital to security
on individual business and national
levels using the quantum principles of
physics could help make networks
unhackable a secret key is distributed
between two parties and cannot be a
intercepted without collapsing
traditional networks are secured of
mathematical problems or encryption
which can be resolved and thus hacked
but by using random values and the BB 84
protocol we can check Ella lates to
detect hacking attempts while quantum
network equipment has mostly enabled
data centers to connect with a single
receiver or clients we have successfully
tested a system with multiple receivers
hands team aims to develop this multiple
receiver system and make the equipment
smaller while increasing the distance of
data transfers Korea science ministry
aims to invest more than 37 million u.s.
dollars over the next five years to
develop a five qubit quantum computer
and a hundred cubic machine by 2027 Oh
