The Quantum World- Error Correction

 A major disruptor in technology is quantum computing. It can actually turn out to be a bigger game changer than other technologies such as AI, blockchain, etc. The reason the others at the fundamental hardware level are nothing more than a string of 0's and 1's. Quantum computing changes the very fundamental way of how a computer works.  For example imagine you toss a coin. If you let the coin fall and observe it, it will either be either heads or tails. Now imagine if you spin the coin on the table. It is difficult to tell whether the coin is heads or tails. In a way you can say it is both. The reason why quantum computers are powerful is because of this one property(although not limited to it). A computer has a bit which can be either 0 or 1. 0 implies turned off and 1 implies turned on. A quantum computer has qubits which can be 00 ,01, 10 and 11. These might not seem significant when you have very few qubits compared to bits but when increased they have a massive increase...
