Quantum revolution: How Tomorrow's Computers Will Challenge Today's Cybersecurity 



The Future of Quantum Computing and the Impact it has on Cybersecurity

 Quantum computing is rapidly becoming the most transformative technology this generation has ever seen. This technology helps to revolutionise various industries, from healthcare to finance, it can be outstanding. However, although this can be exciting, there are challenges we face with quantum computing such as cybersecurity issues. Throughout this blog, we'll dive deeper by looking at what quantum computing is, it's current state and the risks it has with cybersecurity. 

                  What is Quantum Computing?

Quantum Computing is based on the ideas of quantum mechanics, a branch of physics that explains how tiny particles like atoms behave. Unlike classical computers, which use bits to represent data as either 0 or a 1, quantum computers use qubits. Qubits allow quantum computing to handle and process information in ways that a classical computer can't, allowing them to be extremely powerful but also creating problems. 

 

Current State of Quantum Computing

In 2019, Google announces they had achieved "quantum supremacy", this refers to quantum computers solving problems that is impossible for a classical computer to handle.

Although, there has been such achievement, there is still likely a decade or even more away from developing quantum computers that are both practical and scalable for widespread use. However, despite these challenges, the push to advance quantum computing is intensifying, with investments from governments and private sectors. China, for example, has heavily invested in quantum research, with the hope of becoming a world leader in this field. 

 
Benefits of Quantum Computing  

Within healthcare, quantum computers could simulate molecular structures at unprecedented speeds, leading to faster drug discovery. I finance, they could optimise large-scale portfolios in seconds. 

One of the most promising applications of quantum computing is in the field of materials science. Quantum computers have the potential to revolutionise how we design materials by allowing scientists to simulate and create substances with precisely tailored properties. This has the potential for extreme breakthroughs in areas like battery technology, enabling the development of more efficient and powerful materials than ever before. 

 
                          


Cybersecurity Implications 

Today's encryption technologies, like RSA and ECC, depend on the complexity of factoring large numbers or solving intricate mathematical problems.

However, quantum computers could unravel these problems at a much faster rate, making current encryption methods ineffective. Meaning the data secured with today's encryption could be at risk of being decoded by quantum computers in the future, which creates  serious threat to areas such as financial transactions and national security.

 

The Future Outlook 

As quantum computing gradually evolves, as will strategies to defend against cybersecurity. IT companies must stay aware of this and continuously update security protocols and investing in quantum research. 

Although, practical quantum computers may be years away, the time to prepare for this is now. Stay informed and proactive, organisations can ensure they are ready to face the quantum future, harnessing its potential while safeguarding against its risks. 

 

Conclusion 

Quantum computing is poised to be one of the most ground-breaking technologies of our era, having the capabilities of revolutionising industries and tackling problems that are currently unsolvable. With such immense potential comes with great responsibility: safeguarding cybersecurity in the face of quantum advancements. As we approach the dawn of the quantum age, it's imperative that the IT sector unites to craft and deploy strategies that shield our digital landscape. Ensuring that the benefits of of quantum computing are realised without compromising security.

  UK PSTN Switch Off Begins: How Will It Impact Your Business From 2020 onwards you are no longer be able to purchase integrated services digital network (ISDN) and public switched telephone network (PSTN) circuits in the United Kingdom. As of 2025, the PSTN circuits will be shut off completely. This is a major step towards the United Kingdom’s mass IP-network migration, with VoIP core networks set to replace all of the outdated legacy technology. What is ISDN? Integrated service digital network (ISDN) is the first iteration, launched years ago, of high-speed internet. ISDN first appeared in the 90s and revolutionised internet connectivity. Many credit the technology as being the groundwork for modern, faster internet solutions.  What is PSTN? The public switch phone network (PSTN) is what you might refer to as the classic analogue telephone system—the system that enables landline connectivity. This centuries-old technology was introduced during the 1800s and allows ...

  This new search feature in Edge is a revolution Microsoft’s at it again, presenting us with new features week after week. This time it’s all about making our online searches smarter and more efficient in the Edge browser. If you’ve been on the fence about switching to it, this might just be the push you need.   Edge has a cool new feature, as revealed by Mikhail Parakhin, CEO of Advertising and Web Services at Microsoft. Imagine this: you’re searching for something important for your business – maybe it’s market research or the latest trends in your industry. You type in your query, and you get results from not one but two search engines at the same time. How does it work?   Let’s break it down. Say Bing is your default search engine. Now, when you hit the search icon, you won’t just see Bing’s results, you’ll also get a peek at what Google (or your alternative search engine of choice) has to offer. This dual view works both ways, ensuring you’re not mis...

  Are you using the all-new Teams yet? Microsoft is rolling out a brand-new version of Teams, its video conference, collaboration, and chat platform. We’re being promised a faster and easier way to work. And we all could use a bit of that, couldn’t we? The new Teams is like the superhero of apps for Windows and Mac. It’s faster than a speeding bullet… well, at least twice as fast as the classic version. Plus, it’s on a diet, using up to 50% less memory and disk space. Microsoft went back to the drawing board to reimagine it, make it simpler and more flexible. Now Teams: Plays better with third-party apps Is happier calling phones outside of Teams Gets you into meetings quicker than you can say “not another meeting” This pumped-up version of Teams uses some tech which allows it to share resources with your browser. That reduces how much memory and disk space it needs. And the initial test results? Teams is twice as quick when loading the app, joining meetings, and swit...
