Does Bitcoin Have A Quantum Computing Problem?


Google claimed quantum supremacy recently. That sent Bitcoin enthusiasts into uncharted territory. Traders, who are typically easy to spook, have the most to lose – or gain – from the implications that quantum computing might have on Bitcoin and other cryptocurrencies. But what are those implications at this point? Does Bitcoin really have a quantum computing problem? How can it be addressed?

Quantum Supremacy

To understand how Bitcoin and other cryptocurrency communities should react to Google’s announcement, it is important to delve deeper into what this quantum supremacy claim entails. According to Andreas Antonopoulos, this is what Google really achieved:

  • Up until now, quantum computers didn’t have a significant advantage in terms of solving problems faster than regular computers
  • Google’s experiment showed for the first time that a quantum computer could solve a problem significantly faster than a regular one
  • What Google means by quantum supremacy is that their quantum computer solved a problem that would take a regular computer thousands of years, which proves that quantum computing works
  • This doesn’t mean that quantum computers are ready to take over or are an imminent threat to the level of cryptography that Bitcoin currently has
  • For quantum computing to threaten Bitcoin and other cryptocurrencies, thousands of qubits – quantum bits – of quantum corrected calculations
  • Google’s quantum computer has 100 qubits of power
  • The problems that Google’s computer solved are not necessarily the kinds of problems a computer needs to solve to break Bitcoin’s encryption

Google Lied About Quantum Supremacy

Therefore, Google lied when it claimed quantum supremacy. That is because supremacy entails the ability to use quantum computer on a wide range of problems, systematically and effectively. Google is still far from this, which is great news for Bitcoin, cryptocurrencies and mostly traders.

Quantum Supremacy Threatens the Whole World, Not Only Bitcoin!

Traders of course rely on various platforms and on the international financial system for their livelihood. Quantum computing has the potential to threaten every kind of encryption that is currently deployed. That means:

  • Traditional financial platforms and infrastructure
  • Communications
  • Any kind of service based on internet accounts and passwords

So, if you are a trader on a platform like eToro, you should be relieved to know that you don’t have to scramble to liquidate every single position you have and make sure you bring a Brinks truck home with gold bars and cash. You will be able to keep on trading Bitcoin and other assets because every single platform you use is still reasonably safe.
