5 Things to Know About Quantum Computers' Error Correction : A New Dream

Quantum Computer

Most people assume that getting Cox customer service and installing remarkable home security devices is the extent of technology. However, they couldn't be more wrong! Even after the internet, artificial intelligence, and all this fantastic revolutionary technology, there's more: Quantum Computers!

Luckily, scientists were able to figure out how to make quantum computers. However, despite solving remarkably complex problems, it had a big problem. Quantum computers made errors, and these errors could potentially be devastating. Only recently, Quantum experts have figured out a solution to this problem. And it's called Quantum Computers' error correction! 

5 Things to Know About Quantum Computers' Error Correction

In the simplest form possible, here are the most important updates on Quantum Computers and their self-error correction: 

#1. Quantum Computers Can Make Errors

Despite the hype around quantum computers, these technological machines are still machines. And like any other computer, they also make mistakes and errors in calculations. In fact, the chances of an error are specifically higher in quantum computers. Why? Because They perform more complex calculations. The more complicated this problem, the higher the chances of mistakes in the results. Hence, despite what many people believe, quantum computers are powerful, but they are not error-free. 

#2. The Obstacle of Building a Large-scale Quantum Computer

The potential solution to this problem (high number of errors in Quantum calculations) is by combining multiple qubits and merging their power into one. According to scientists and experts, doing so can potentially reduce the error problem and make calculations more accurate.

Typically, scientists utilized nine individual qubits and made a single one. This resultant qubit is supposedly an improved version: the logical qubit. The difference between a logical qubit and the parent qubits is that one can probe the former and check it for mistakes. This demonstration is a critical development in creating a large-scale Quantum computer.

#3. Self-Error Correction

Self-error correction refers to the phenomenon of computers fixing their own mistakes without making any new ones. Since researchers have developed this solution to their problem, there are no fundamental obstacles between them and building a practical, usable Quantum computer.

But despite figuring out this solution, the path to implementing it is still a very long and complicated one. Scientists have to increase the number of qubits in quantum machines by a dramatic scale. And even though it sounds relatively simple, it can actually take a really long time for them to accomplish. Hence, self-error correction for Quantum machines has been figured out, but will it become a reality soon enough? 

#4. Bacon-Shor Code

To make logical qubits a reality, researchers are now using the Bacon-Shor code technique. They applied this technique to individual qubits made from ytterbium. These ions hover over ion-trapping chips placed inside vacuums. Scientists can then manipulate this setup using lasers.

Researchers have also recently designed the individual operation sequences to help them minimize the chances of uncontrollable multiplication of errors. Such a phenomenon is called "Fault Tolerance'' which can potentially be avoided. As a result, the resultant logical qubit will potentially have a reduced error rate than the flawed parent components. But how far are scientists on this path, and how long will it take to solve this problem altogether? 

#5. The Quantum Dream Is Close to Being A Reality 

Every day, quantum computers are becoming more and more practical. They are becoming more usable, accessible, and applicable in everyday lives. Companies have started investing in these quantum devices, including Intel, Google, IBM, and other renowned names in the market.

Experts claim that complete error correction in quantum computers is almost achieved. Tiny steps are slowly completing the ladder towards this dream becoming a reality. The only things standing in the way of ultimately hitting this target are financial limitations, time restrictions, and the availability of funds. However, slowly but eventually, experts will be able to overcome these obstacles and turn the impossible into possible! 


If quantum computers successfully achieve error correction, their usability and functionality will increase by several folds. Finally, this powerful technology will become usable by companies, industries, and the regular public. The goal of making quantum computers a mainstream technology, like smartphones, seems more and more achievable every day!
