Quantum Computer Answers Can Now Be Checked for Accuracy

A quantum computer can do a lot of things even the most powerful traditional supercomputers cannot. The only problem with them, however, is that they're extremely sensitive to external contamination. This makes them prone to errors despite their insane levels of processing capability.

Back in 2019, a team of scientists from the University of Warwick tried a similar but fundamentally different approach to the whole "machines checking machines" concept: they developed a protocol for a quantum computer to measure how close its answers are to the correct ones, reports SciTechDaily.

Once the questions of accuracy and reliability are solved, the world will be free to unleash a quantum computer's almost unlimited processing potential to advance scientific research to heights previously unimaginable.

Why Does This Matter?

In the simplest terms, A quantum computer possesses processing power that not one, two, three, or even four powerful supercomputers can match. Case in point: China's Zuchongzhi quantum computer, which its creators say can dwarf the performance of Google's Sycamore machine at 66 qubits of theoretical performance. Sycamore can only manage 53 qubits.

In a head-to-head battle, the creators of Zuchongzhi claim that their machine is an insane 10 billion times faster than Sycamore. Here's some perspective for you: a problem that will take Sycamore 10,000 years to process can be solved by Zuchongzhi in over 3 minutes.

Imagine that kind of processing power being employed with little to no risk of wrong answers being given.
