Medicine & TechnologyPhysicists from Yale University have developed an "error-correcting cat". This device combines the concept of superposition from the famous Schrödinger's cat experiment, and the ability to fix some of the persisting problems with quantum computation.
Differences between these computing types are night and day, both work differently compared to each other except that quantum computing needs more development compared to the other. Suffice it to say that quantum computing is the next level computing type in-waiting.
