"so this could be bad for crypto as you could hack a unhackable key in a lot less time using a quantum computer."

Only certain encryption algorithms are susceptible to quantum cracking.

"no cryo-cooling required"

Ok, but can it improve Pornhub streaming quality??

Having fun with OPM. Until the story falls apart.

A true general purpose entangled computer which can easily defeat modern encryption would destroy the economic model of the Internet.

That’s why I doubt we’ll ever hear of one being developed for real. Just the confirmed knowledge that it exists, would inflict the damage and essentially destroy the Internet.

The world we know hangs by threads of secrecy.

No. You are confusing quantum computing with the aspect of quantum mechanics that implicates consciousness in certain highly structured quantum observations.

I know my understanding of quantum physics is below basic, but they are quantum computing, which I’m not sure of the difference.

...or do a data sort in Excel. It is amazing how little about using basic software most people know.

I got one for ya. A fellow employee was working on a spreadsheet with several pages of property values (in Quattro Pro IIRC). She was punching numbers in an adding machine. I asked her what she was doing. "I'm adding this column of figures." After a few face palms, I patiently showed her the basic function of a spreadsheet. Some time later I saw her still plunking on the adding machine. I gave up.

There are of course connections between quantum computing, quantum mechanics, and consciousness. The explanation of how that is so is complicated but I'll give it a try and make clear why thoughts alone do not impact quantum computers.

A fundamental insight of quantum mechanics is that photons and it seems nearly all matter on the smallest scales have a dual nature as both particles and waves.

In the simplest example, light passed through a carefully constructed double slit interferes with itself so as to produce a diffraction pattern of dark and light that indicates light is in the nature of a wave.

The same effect can be demonstrated with waves on water or even sound waves. That is simply how waves work, with waves reinforcing or cancelling each other.

Yet light also consists of individual particles called photons. And when the double slit experiment is more closely analyzed, the waves of light can also be identified as consisting of discrete photons -- and those photons interact with each other like waves.

The mind boggling part is that photons passing through the double slit experimental arrangement are entangled and "know" where their colleagues in the wave are and to react depending on whether the other slit is open or blocked. Thus such photons react instantaneously to interfere with or reinforce the photons that are potentially passing through the other slit.

Quantum entanglement and quantum interference are deeply complicated and philosophically troubling. Einstein called entanglement "spooky action at a distance" and spent decades fruitlessly trying to disprove its existence.

Moreover, after decades of experimentation, it has been demonstrated beyond question that for particles to be entangled or for their behavior to be analyzed requires an observer. More broadly, without an observer, quantum states are also indeterminate.

Thus it is said of Schoedinger's cat that if it is used in an experiment so that it lives or dies depending on the chance of a quantum event happening, until the experiment is checked, in a philosophical and practical sense, the cat might be either alive or dead. The implications of this are either trivial or profound depending on the specific theory of quantum mechanics one prefers.

As for quantum computing, in concept, it relies on quantum entanglement to carry out certain types of mathematical operations. Broadly, particles are made so that they are entangled with each other and programmed so that only one combination does not cancel each other out through quantum interference. That one valid combination is the answer sought.

Again, as with the double slit experiment, the entangled particles in nature or in a quantum computer "know" in some fashion that they are entangled with other particles and react to what is happening with them. The larger implications can be taken as meaning that some form of consciousness pervades all matter, with some referring to modern quantum mechanics as a philosophy of panpsychism.

To get back to your suggestion that thoughts might affect a quantum computer, in quantum mechanics (so far at least) even though an observer is needed to determine a quantum state, the observer has to act, not just think about acting. Granted, the connection between our minds and our actions in the world requires a connection between thought and matter, that is a different matter than having thoughts alone affect a quantum computer. So far at least.

“I developed a quantum smartphone, but every time I opened an app, a cat died.“

Or not. ;-)

A hypothetical cat may be considered simultaneously both alive and dead as a result of its fate being linked to a random subatomic event that may or may not occur.

“not exactly, you can protect against quantum hacking.”

Could those quantum computers produce bitcoin quicker?

When the supply of coins goes up, the value should drop.

Do supply/demand rules apply to bitcoin? Or is more money(bitcoin) is printed to meet demand.

Bitcoin supply is fixed at 21 million.

I was just reading that in another article. So they will limit the supply of bitcoins to hold the value.

ZARDOZ computer. Just needs a little “mad max” anarchy to make it work.
