South Korea Working Towards Quantum Network, Unhackability of Communications
S. Korean quantum computing scientists working on next-generation networks and ‘unhackable’ technologies
Excerpts and salient points ~
+ Quantum computing researchers at Korea Institute for Science and Technology have developed ways use diamond structures to produce qubits.
“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.”
+ Korea’s science ministry aims to invest 37 million U.S. dollars over the next five years to develop a five-qubit quantum computer, and a 100-cubit machine by 2027.
+ Traditional networks are secured with mathematical problems, or encryption, which can be resolved, and thus hacked. But by using random values and the BB84 protocol, we can check error rates to detect hacking attempts. While quantum network equipment has mostly enabled data senders to connect with a single receiver, or client, we have successfully tested a system with multiple receivers.
