Schrödinger’s Quantum Cat Awakens to Revolutionize Computing

In a groundbreaking experiment, UNSW researchers successfully applied the Schrödinger’s cat concept using an antimony atom to enhance quantum computations.

This method significantly improves the reliability of quantum data processing and error correction, potentially accelerating the advent of practical quantum computing.

tl;dr== Rather than just spin up or spin down, the muclear spin of antimony has 8 values. This provides robustness against errors.

Well, since the Internet is largely made up of cat videos, it stands to reason that a famous cat would assist in the creation of even more computing power.

Studied physics (mystics) in school. Antimony’s best use
is to harden lead as in Lyman #2. Spin is clockwise exiting a barrel.

I’ll never understand how lab equipment can monitor something as small as an individual atom. Especially taking Heisenberg’s uncertainty principle into account (changing it by observing it).

Quantum computing will spell the end of e-commerce because encryption will no longer keep online financial accounts and transactions safe. Even blockchain will be of no use.

We will have to return to physical money and face-to-face transactions.

Almost like real human beings.

SchrÖdingers Cat is silliness. The cat is in fact alive or dead, one or the other, wether you can see/know it or not. A=A

It's just that there's a lot of negativity on the internet now. I don't know why that is. I try hard to be positive and it ain't easy. But articles like these that are exclusive instead of inclusive sadden me. Think of it. They are putting it out there that they are ANTImony. Me, I'm pro Mony.

Theoretically, quantum computing works because of the uncertainty principle, not in spite of it. The qubit, which is usually an electron (much smaller than an atom!), maintains a superposition state of 0 and 1 at the same time, unlike a conventional computer bit, which must be 0 or 1.

Lab equipment doesn't monitor the qubit when it's in the middle of quantum computing processing. Lab equipment measures the results of processing. Because as you and Heisenberg know, once you observe or measure the qubit, its superposition will collapse and become a known state - just like a regular computer bit (0 or 1).

Quantum vs. Classical.

That's what Einstein thought too, and he spent the second half of his career trying to disprove the theory of quantum mechanics. But Einstein was wrong. Physicists have known since the 1950s that all elementary particles in the universe exist in multiple states at once, until it is measured of observed, then its superposition collapses to a known state.

Schrodinger's cat really is dead and alive at the same time until someone or something makes an observation or takes a measurement. Quantum mechanics is best described as: "the moon doesn't exist unless a mouse looks at it."

Not a true observation but this is an interesting device.

If one is south of the equator, counter clockwise may be preferable.

Lyman #2 clad in copper opens up new worlds.

“Because as you and Heisenberg know, once you observe or measure the qubit, its superposition will collapse and become a known state - just like a regular computer bit (0 or 1).”

So if I store a 1 in the qubit, then when I go read it back, you say it could be a 1 or a 0. What good is that? I want to read back what I stored with 100% certainty!

I don’t see how this “superposition” is of any use in building a reliable computer.

[StolarStorm]

"until it is measured of observed, then its superposition collapses to a known state."

The only explanation for that is that we are in a simulation. It's "cpu" conservation, things change when "we" observe it but stay in a ambiguous state until we do.

[Right_Wing_Madman]

I don’t see how this “superposition” is of any use in building a reliable computer.

Superposition increases your computer processing power exponentially (2^n and n = number of qubits):

3 qubits = 8 conventional bits
10 qubits = 1024 conventional bits
20 qubits = 1,048,576 conventional bits
30 qubits = 1,073,741,824 conventional bits

I have this t-shirt

and the cat also

[aquila48]

But if I can’t read back what I stored with any reliability (because of superposition), what good is any of that?

And those numbers of yours only make sense if I can reliably store (and recall) TWO bits for each qubit. From what I gather a qubit can only be a single binary bit (1 OR a 0) at any point in time and you don’t know what you’re going to get until you read it.

Tell me, how would you add 1+1 with qubits?

Or, even simpler than that, how do you go about storing a 1 in a qubit and then guarantee that you’re going to get a 1 when you read it back?

[Right_Wing_Madman]

The only explanation for that is that we are in a simulation.

Another theory is that a very high number of universes are created at every instant.

There is the universe where Schrodinger's cat is alive and another one where he's dead.

There is a universe where Notre Dame beat Penn State in the Orange Bowl, and another universe where Penn State beat Notre Dame in the Orange Bowl. You and I observed the universe where Notre Dame won.
