Within the next two decades, experts believe that quantum computers will replace the “classical” computers we use today, and will completely change our lives.

Using elements from quantum physics, they will be able to build these computers, which can explain climate change and even discover new drugs.

Meanwhile, Google claims to have managed to build such a computer as of now. According to them, this computer is capable of making calculations that would take current computers 47 years.

However, this claim raises strong shadows of doubt, since even in 2019, the technology giant claimed such a thing, while this was later rejected by its rivals.

Google’s rival, IBM, said at the time that Google’s quantum computer “Sycamore” was not fully functional and could only perform some operations, which can also be done with classical computers, albeit more slowly.

Currently, similar work is being done by the University of Sussex in the United Kingdom, supported by major technology companies.

However, the realization of a quantum computer that everyone can buy could take about two decades. The latest realizations still remain in the experimental phase.

Quantum computers can destroy banking systems with the push of a button.

Andersen Cheng, Founder and CEO of Post-Quantum, warns that quantum computers could be used for destructive attacks on energy networks or the global banking system. Researchers have stated that quantum computers, many times faster than the ones we use today, can easily break through defense systems. This type of technology is already in development.

“Quantum computers will be millions of times faster than classical computers, thanks to the fact that they use qubits.” This incredible improvement means we have to be ready for it before it happens, as it would be too late. “There’s a secret quantum arms race going on that we don’t have much information about,” Cheng said.
