Quantum computing

The world's problems keep changing. About a century ago, there was  The Great. In the 70s, there was a fear of nuclear war. Then, in 1999, people thought the coming millennium would shut down computers due to the date change. Some constant problems that have existed since time are poverty and bias. Now there is hunger, energy problems, disease and multitudinously more. But what if I could share you a solution to today's issues.

In recent years, people have come up with new technology. It is different from the traditional silicon chips. It is computing at the smallest possible level, the level of atoms. Yes you heard me right. A computer computing with the bits and bobs of the universe. They may sound like a minor change, like,' Oh, maybe gaming will change, or computers will be a few milliseconds faster,' but no, they can compute anything. 

The thing with normal computers is that simulating certain things in a proper manner can take a lot of data. For example, if scientists want to compute a chemical reaction with unknown chemicals, it will take up lots of data, not just in peta bytes but in millions of yottabytes, more than the data ever made. But quantum computers play a new game. They use qubits, with the advantage of entanglement, superposition, etc., and can compute reactions in just a few thousand or maybe even a few hundred qubits. Plus, for every qubit added, the quantum computer's power doubles.

But it is a new technology, so barely anything has been achieved. But some computers have achieved quantum supremacy, which means doing calculations on traditional computers takes years. In 2019, sycamore of Google and NASA calculated 200 seconds, which would take the best silicon supercomputer on Earth 10000 years. And IBM, Microsoft, etc., catching up. 

 

With quantum computers, we can simulate anything. We can simulate body functions to find the core of diseases and hopefully try to develop cures or interventions towards it. We can also simulate certain mitochondria functions to see how ATP forms. We can simulate energy sources in a safe manner. Test gadgets with little to no success to see if they would be worth making. Simulate space and use that information to determine how the universe was formed. There are many more, or I can say everything. 

I got most of this information from 'Quantum Supremacy' by Michio Kaku. If you want to know more, than read it.
