Differences between these computing types are night and day, both work differently compared to each other. Except that quantum computing needs more development to compare to the other. But Quantum computing is the next level and waiting.
For many, this will be a confusing question, and the concept of quantum computing is no better than the arcane arts that work like magic. But, the differences in how quantum and classical computing works is more arcane than most would think for these quantum gadgets are powerful yet not fully developed like normal computing. Still, in its early stage, quantum computers are all set to be the next frontier to our computers now.
For now, unlike current computing with programming languages that take advantage of its vast, yet limited power to figure out computations. On, the other hand computing using quantum machines are still under development and intense scrutiny. This scrutiny is the examination and improvement of the quantum machine that will be next-gen. Laptops are getting more powerful, but master the development of quantum language and programming. Any quantum machine the size of a laptop promises more computing power, best data handling, and last shrinking of supercomputers to a portable size?
Everything about quantum computing is on the conjecture or the stage where everything is at an experimental stage. Before the coming of miniaturization and silicon chips, computers were very bulky that fit into rooms. Supercomputers are about to calculate data without whole rooms, to house it. Even data storage was limited too. A single USB will hold one terabyte for data compared to older data storage systems. If a mobile phone became a quantum computer, it can figure out immense computer models and explain it.
No need for direct interface with the quantum machine, using normal computers and the digital cloud to enact calculations for research. Also, these are just prototypes with extreme sensitivity that errors are experienced. One explanation of why errors happen is that interaction is based on superposition, anything can set it wrong. It may be that quantum entanglement is so sensitive, which needs a perfect environment for it to work flawlessly.
Tasks that a quantum computer can do, and how complex are the tasks it can do. Everything does get interesting from here, and a quantum computer is a new frontier for advanced new applications. The range of this arcane yet powerful tool is making medicines, research into new drugs and cures, development of new materials, and even financial predictions (quantum finance) which some parties are very interested in. Quantum computing is like delving into super-science like temporal calculations in any amount of time, with enough accuracy? The key is superposition that can exist in one state to another, like 20 years later what stock will best. With quantum computers on the horizon, the possibilist are endless.
All these variables are vast, when it comes to quantum and classical computing are night and day. For now, quantum computing is at its infancy and waiting until it becomes as normal as using laptops. Eventually, as quantum computing gets better and the device itself goes to commercial use, this will be the age of the quantum data.
