I would like to know more about quantum echanics and its applications?

Question

it seems to me that we heard alot about quantum therory a few years ago, but not much anymore. acording to scientists quantum will open up all kinds of new demensions for the betterment of our lives eg; medicine , artificial intel, etc..

Answer 1

We are currently living in QM technology society.

Applications:

laser

transistor, (tv, computers, cars, ...)

MRI

USB drives

modern chemistry

and so on

Ans it is only a beginning.

Answer 2

Well the main application, if you can call it that, is to discover the features of our universe and the particles that it's made of. And it's a prime influence for many unifying theories of physics. i.e. theory of everything.

But if you're looking for conventional applications, well, a lot of technology like lasers or MRI tech operates at the quantum level. So the more we know, the better we can design such technologies. Even in chemistry, you can use quantum mechanics to study bonding, find out which atoms or molecules are most compatible with each other. But a big hope for quantum mech is that it can be used to design quantum computers. These comps will probably be able to do calculations thousands or even millions of times faster than digital computers. And then there's quantum cryptography, which means information can be transferred securely and is pretty much non-hackable or can't be intercepted.
