Quantum technology and implications for security in todays computer infrastructure


Welcome to the cybersecurity weekly podcast. I'm jay lewis podcasting from singapore today joining us today. We have a very special guests from switzerland who is based in zurich. And he's a doctor khumalo. Got the donnie. Who is the security researcher. We've could ask security so thank you very much for joining us today jane. I'm very happy to be here with you today. To be honest to it's quite difficult. Also for ricardian super announced. So don't worry about that. So so the first question. I think many of our listeners will be quite keen to know is is quantum computing a high. Because when you read the news and media nowadays we see a lot of investments that have been announced by governments for example the us national science foundation and the department of energy announced. I think with more than one billion over. The next five years in quantum information systems and russia and germany also not far behind announced close to seven to eight hundred million investment china as well spending time billion on the effort. In the private sector's google and ibm are also spending in excess of one hundred million and even bangs like j. p. Morgan is also looking at developing quantum lonzo banking but on data hen. Also some in saying that quantum states are not reliable stable or quite understood well enough to replace the traditional classical computers and some believe that they will never be able to do so. So my question to you is is quantum computing a hype well All these people you mentioned are very smart so if they spend all this money it must be true right now. Kidding apart we have seen tremendous tremendous advancements in this technology in the in the latest ears. So just put it into perspective. So people started discussing about quantum computing. Already more than fifty years ago but it became interesting. I would say nineteen ninety-four with the discovery your applications for cyber security now. At the beginning people were thinking. Okay this is something very interesting from a theoretical point of view. It will never be real. You know it's it's kind of Would be something like Science fiction like however then after that we have seen continues continues progress on the on the research and development and we especially in the last few years we have weakness a situation from you know we can be really controlled. One beat of quantum information to prototypes. That are actually working. So they are still prototype so they are still not powerful enough to tackle Real world problems. But i wouldn't call it to hype this point so from my personal point of view. The trend is quite clear. So you mentioned the difficulties. In controlling information and the related technology so from from a theoretical perspective the technologies well-understood now. There is engineering challenges into building. Something that is working but this is the case we any brand new technology. I mean justice I transistors. They were big bulky. They were barring city You remember the famous quotes like sixty four. Kilobytes of memory should be enough for an anyone. That's right so like every new technology. There is challenges. So what i see is that from a technological point of view the the tuition is progressing much more rapidly than many expected to ten years ago. Now the question. Everybody's asking his okay. But when are we going to have computers. That are not prototypes anymore. That are something that can solve real world problems My impression is that we are very close to the point but there is a difference in what you consider useful because a lot of people say like okay when we'll quantum computers break cryptography. Well i i think that's not a good measure of progress for quantum computer because quantum computers can do much more than that.
