Quantum computer

Though quantum computing is still in its infancy, experiments are undergoing to see if they can light up more areas into the making of Quantum Computers


In a classical (or conventional) computer, the amount of data is measured by bits; in a quantum computer, the data is measured by qubits

Bits vs. qubits

The computer as we know it has a memory made up of bits, But as and when Quantum computers come out, they will have the memory made up of qubits

Also our home computers operates on a 3 bit register. the bits in the register are in a definite state, such as 101.

In a quantum computer, however, the qubits can be in a superposition of all the classically allowed states. In fact, the register is described by a wavefunction:

Right, this is just some bits i got together about Quantum computers and computers as we know them best

Please forgive me if you think this post was pointless, i just wanted to see if i could do a review on it

So, what does everyone think of it?? good or bad?

Cheers and thanks for reading

My self i think its good and interesting, we all learn every day and any information of things to come is a bonus to my mind, thanks for an interesting post

I am always about if you need a quick answer to how to fix a problem

Quantum Computers are a interesting idea. Wonder how fast they'd go. Would they go faster than ALL convential computers today (put together)? Could you imagine terahertz (thz?) speeds with like 1 - couple hundred TB hardrive?

Able to solve some problems in days compared to the many years (up to a century or more) for today's computers.

Yeah they will be mega fast LOLO

Actually if they are faster than all supercomputers put together thz might be a bit small. Petahertz (phz?) Exahertz (ehz?) Sheesh. I wonder how fast the super computers would go!

Remember, processor performance is not dependant on just frequency. Even recent hardware has demonstrated this.

Who knows what hardware we'll have in 10, 20, 100 years? I think I've also read quantum comps don't use transitors -- or do but very speical kinds that utlize the speed of light (or some part of the computer uses C).

You all know Starwars right? or Star trek? well the kind of computers you see them (pretending to use) on there is like what Quantum computers are going to be like.

Beam me up scotty :P:P

Science fiction is an extremely poor judge of computers in the future.

We've already exceeded storage space and processing speed described by science fictions little older than 10 years. If you go back to the 80s, computers not yet scheduled for 100 years from now are painfully slow, large and unintuitive and beep for every character printed on the screen (always struck me are an irritating feature I'd turn off right away).

Even produced today, science fictions often use computing delays, transfer rates and lengthy "recalibration"s as plot devices, which if translated literally, would indicate poorly designed, inflexible software running on hardware starved for processing performance and connectivity bandwidth. On the other hand, fictional characters will dictate rather abstract commands and submit ambiguous questions to voice recognition systems that easily interpret and execute them, sometimes demonstrating advanced comprehension and intuition we cannot even begin to imagine possible today.

All quantum computing offers is faster number crunching. It doesn't guarantee more flexible, smarter or productive computers; that's all down to infrastructure and software/firmware.

The very definition of quantum computing, is rather than logic operations being performed by, and stored, in transistor circuits, they are done at a quantum level by configuring atoms to exist in certain controlled states. It's a loose definition really, but the whole point of quantum computing is to get rid of the reliance on transistors as we know them.
