How long will it take for quantum computing to actually be used in labs, or thinking further out, commercially?  Is it true that it could possibly take decades? I've heard that right now it's not feasible but I guess people are still researching (from my understanding) what would necessary to create a quantum computer, how fast those would be etc.?

Depends on how much funding the lab has access to

Perhaps. Granted this is totally not my area, I'm just curious because of all the hype I hear about it, which, I assume is mostly hype.

My ( limited ) understanding is that it doesn't so much bring a processing speed increase, but dramatically increases the amount of data that can be processed simultaneously.

Which then would certainly increase the processing speed for very large data sets.

Quantum computers exist in the lab and there are allegedly commercial products available (D-Wave started selling one more than a decade ago, though I attended a talk from Bill Phillips, a Nobel prize-winner, who was dubious of their claims)

Hello. There have been developments in materials science that made possible maintaining entanglements up to 130K. That's -143º C. It's still really cold, but previously it was close to 0K. Some korean scientists also alleged last year (2023) that they achieved materials that maintained their quantum properties at room temperature.

So, there have been developments. If the materials allow it, it's feasible. Else we will be looking at new technologies. For example, something really small that would maintain the low temperatures inside the computer core.

There has been incredible advancements into laser technology this year also. So that helps to create new computing technology.

In the end, it all depends on what kind of advancements we can make in the next years, with a focus on materials science. AI will surely help, if it keeps evolving at the pace it is evolving.

Quantum computers are much faster than regular computers because they can sustain 2^n states. You will be looking at something really large at just 16 qubits.

The algorithms need to be developed, but that is not the main roadblock now.

I imagine without the hardware being developed, algorithms couldn't be developed either?
