Quantum Computers today have very high error rates, with some as high as one in every 100 operations. This occurs because of the fragile nature of quantum bits (qubits) and can heavily restrict what tasks you can do with a quantum computer. Therefore, to correct this, we require techniques such as Quantum Error Correction - or QEC for short. QEC is theorised to be one of the missing puzzle pieces in the race for quantum advantage. Now, that’s not to say that QEC doesn’t exist but rather that currently it is not effective enough to achieve fault-tolerance. QEC refers to the ability in quantum computing to protect a quantum state from being altered due to errors caused by decoherence and quantum noise. If we are able to correct errors then even with low fidelity operations on a quantum computer, we would be able to run complex algorithms and yield accurate results. In a sense, quantum error correction is more realistic as it assumes a NISQ (Noisy-Intermediate-Scale-Quantum) computer. There are many approaches to reversing errors and we will discuss some of them today!

In this week’s quantum edition, we are taking a look at some of the most popular quantum computing videos on YouTube. We’ll break them down and highlight the key takeaways, but we will also speak about some of the things which these videos could improve upon. Within the world of quantum computing there is equally as much hype as there is genuine advancement, so it’s important to remain critical of everything you read or watch. That being said, there is nothing more important than educating the masses about science, technology and of course… Quantum Computing.

British scientist Sir Tim Burners-Lee invented the World Wide Web in 1989, whilst he was working at CERN. Believing that it should be a human right to access the internet, he did not patent his creation. Thanks Tim! The internet relies upon transmitting data in the form of 0’s and 1’s via optical or electrical signals (think, fibre-optic broadband). Thanks to the invention of TCP/IP (the internet protocol suite), computers from around the world were unified under a single rule-set and could communicate freely. Before this, the internet was an almost entirely text-based world where users would surf through collections of files and documents. There were no ‘search engines’ and certainly no Instagram. If we go back even more we reach the beginnings of the internet, ARPANET (Advanced Research Projects Agency Network), which was a military and research computer network that only select organisations and universities could access.

Now, if we switch to the quantum computing world we see a similar progression. Although unbeknown to many, quantum computing networks have already been invented and are currently sending information and data back and forth. The ability to reliably send information in the form of quantum bits (qubits) offers incredible opportunities for technological advancement and is currently making waves in almost every sector, from finance to scientific research to military operations and soon in every day life. Let’s dive deep in shall we?

When you hear ‘Quantum Computing’, what most likely comes to mind is a huge and imposing golden chandelier dangling from some incredibly clean laboratory. Inside this chandelier, the monstrous quantum computer churns away at calculations beyond the observers wildest dreams. But is this really always the case? In fact, quantum computers can take form in many other unexpected areas, from finance to gaming to the weather forecast. Today we take a look at some applications of quantum computing that you might not have been familiar with.
