now many countries around the world are
racing to develop a supercomputer based
on the quantum physics South Korea
researchers have been developing
innovative ways to turn quantum
computing into reality
our ASEAN has more on how this could
become reality in our daily lives
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 reach the 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
intercepted without collapsing
traditional networks are secured of
mathematical problems or encryption
which can be resolved and less hacked
but by using random values and the BBA
t4 protocol we can check elevates to
detect hacking attempts while quantum
network equipment has mostly enabled
data centers to connect with a single
receiver or client 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 qubit machine by 2027 Oh
