Accidentally posted an unfinished comment earlier and lost it, but oh well.
That’s a very loaded set of questions for an ELI5 explanation.
The concept of quantum entanglement is that we are able to measure particles in a system based on one observation of parts of the system. So for example, say you have two particles that can either spin positively or negatively that form a system and you know that these particles are entangled and that the system produces a spin of 0. You observe one particle and it’s spin is negative. Automatically, you are able to infer that the other particle in the system is spinning positively.
This concept can be applied to a lot of “non quantum” things. For example, say your friend owns only two pair of shoes and that when he isn’t wearing one, the other pair is on his shoe rack. When you see your friend wearing his red shoes, you know where his blue shoes are. That’s because you know the rules of the your friends shoe system.
One misconception that people have about quantum entanglement is that changing the state of a particle/part of the system automatically changes the state of the whole system. That isn’t true. If you were to steal your friends shoes and wear them on your feet, someone seeing you wearing the shoes wouldn’t be able to tell where the blue shoes are because they are no longer entangled.
One other important concept in quantum entanglement is that the act of observing a system inherently changes the state of that system. If you don’t see your friend wearing his red or blue shoes, there’s no way for you to tell which pair is out and which pair is in. The moment you observe your friend and his shoes, the knowledge you have about the location of the other pair of shoes changes.
Applications of quantum entanglement are hard to explain. It’s present in concepts such as quantum cryptography and key distribution. You can create dice with quantum entanglement properties.
Quantum entanglement has all sorts of applications that make it very valuable in the real world. Especially in quantum computing but also that helps us observe systems and explain things in physics, biology, chemistry and many other fields.
One of the things that sets Lemmy, and the collective fediverse apart from other platforms is its community. Recently, there’s been a large influx of new users (myself included; thus I apologize if this is not the right location for this post). A toxic trait associated with other platforms is the incorrect use of the downvote....
You know those discussions that go further down, so get less and less votes because ppl don’t read the whole damn thing, until they become a back and forth between two people? Remember how many of those end on a single post with 0 upvotes. I hate those. I hate when the Downvote is only used to express “I have nothing to say, but I vaguely disagree”-downvotes.
It’s hard to predict but the extinguish part would come from bigger non-Threads instances implementing compatibility with Thread-only extensions (in the interest of their users, or for money) and fragmenting the community. Threads then becomes the defacto ActivityPub standard. Maybe some instances stay true to the standard but with extremely reduced communities because now they can’t see what other instances are publishing. So now you have to decide between your ideals and your social network. At best, you’re back to square 0.
Quantum computing, a remarkable leap in technological advancement, holds the potential to redefine our computational capacities. Harnessing the strange yet fascinating laws of quantum physics, it could significantly outperform classical computers in solving certain types of problems.
Basics of Quantum Computing
Traditional computers operate based on bits, which can be in a state of either 0 or 1. Quantum computers, on the other hand, operate on quantum bits, known as qubits. Unlike traditional bits, a qubit can exist in both states simultaneously, thanks to a quantum principle called superposition.
Superposition increases the computing power of a quantum computer exponentially. For example, two qubits can exist in four states simultaneously (00, 01, 10, 11), three qubits in eight states, and so on. This allows quantum computers to process a massive number of possibilities at once.
Another key quantum principle quantum computers exploit is entanglement. Entangled qubits are deeply linked. Change the state of one qubit, and the state of its entangled partner will change instantaneously, no matter the distance. This feature allows quantum computers to process complex computations more efficiently.
Applications of Quantum Computers
The unusual characteristics of quantum computing make it ideal for solving complex problems that classical computers struggle with.
Cryptography is a notable area where quantum computing can make a significant difference. The capacity to factor large numbers quickly makes quantum computers a threat to current encryption systems but also opens the door for the development of more secure quantum encryption methods.
In the field of medicine, quantum computing could enable the modeling of complex molecular structures, speeding up drug discovery. Quantum simulations could offer insights into new materials and processes that might take years to discover through experimentation.
Challenges in Quantum Computing
Despite its promising potential, quantum computing is not without challenges. Quantum states are delicate, and maintaining them for a practical length of time—known as quantum coherence—is a significant hurdle. The slightest environmental interference can cause qubits to lose their state, a phenomenon known as decoherence.
Quantum error correction is another daunting challenge. Due to the fragility of qubits, errors are more likely to occur in quantum computations than classical ones. Developing efficient error correction methods that don’t require a prohibitive number of qubits remains a central focus in quantum computing research.
The Future of Quantum Computing
While quantum computing is still in its infancy, the rapid pace of innovation signals a promising future. Tech giants like IBM, Google, and Microsoft, as well as numerous startups, are making significant strides in quantum computing research.
In the coming years, we can expect quantum computers to continue growing in power and reliability. Quantum supremacy—a point where quantum computers surpass classical computers in computational capabilities—may be closer than we think.
Quantum computing represents a thrilling frontier, promising to reshape how we tackle complex problems. As research and development persist, we inch closer to unlocking the full potential of this revolutionary technology.
Quantum computers aren't faster because they "process" multiple "possibilities" at once.
@hetscop I thought eigenstates/qbits were what made quantum computing faster and gave it its additional capabilities. For example, if you had an 8-bit integer represented by a bunch of qbits in a superposition of states, it would have every possible value from 0-256 and could be computed with as though it were every possible value at once until it is observed, the probability wave collapses, and a finite value emerges. Is this not the case?
I read up a bit on Shor's algorithm, and while I don't fully understand it all it seems to take advantage of superposition of states destructively, which sounds a lot like "processing multiple possibilities at once."
When we input a superposition through our system and measure the remainder, we get a superposition of all possible powers that result in only that remainder. And this remaining superposition repeats with a period of the power [math didn't paste nicely]
Just as a classical Fourier Transform translates a wave as a function of time into a function of frequency, so too does a Quantum Fourier Transform (QFT), with a superposition as an output with a frequency of the input.
So, if we input a single state into a QFT, the output will be a superposition of states with varying weights or probabilities that form a wave with the input state as the frequency. And if we input multiple states into a QFT, the output will be a superposition of superpositions - with destructive and constructive interference combining superpositions into one wave. And if our input to the QFT is a superposition with period [math didn't paste nicely] source
If my understanding is inaccurate, can you recommend a good source to understand this? Thanks!
I had like 10 posts as of yesterday, amounting to about 3k post score. Came on here today to show that I have 0. Anyone know what happened? The two communities I created still exist, but all the posts I made are gone.
I tried pirating a game on my server earlier, but it was stuck at stalling, when 1337x says it’s got about 100 seeders. I pinged a site from my qbittorrent container and it worked, so it has internet, but it’s just not torrenting....
I'd get the fourth sword, then I'd take a regular dagger, and cut open a pregnant cow or cat or dog or something. I'd then slay all the kittens or calves or puppies with my new sword. Since the animals are not born yet, they would have an age of less than 0. When we add their negative age to mine, I'd become weeks or even months younger per kill! With this I will have everlasting youth!
Yes, it just means that there are 9 people from vlemmy that have subbed to that community. This bit is a bit confusing, for example if nobody had subbed to it yet from vlemmy then it would show 0 subs.
Hi, as it’s in my title. I’m looking for narrative driven games with good story, something I can play on my steam deck. Not something open open world but more of a on rails experience....
A lot of great games already mentioned here. If you want to try something a little different. Yakuza 0 has a bonkers story that is weird and wonderful, but very Japanese.
Tacoma and Gone Home are great stories and well worth a look.
I also rate the Max Payne series for some pulpy fun story with lots of shooty in between.
It discourages people from voting if they’re concerned about other people seeing their activity. This could result in a lower quality of scoring for posts.
I strongly disagree with that. I think showing downvotes makes your votes more relevant. If something has 10k up votes and 10k down votes, it’s probably a decent post. If it just shows 10k up votes, or 0 net total, the score doesn’t reflect the nature of the post.
At the individual level, it lets you know if someone is just trolling. That’s also a plus as far as reputation goes (not sure how people are scored here, or if they are).
i downloaded a torrent file, and for good practice started seeding overnight reaching more than the 1:1 ratio, should i just delete the file or is there a way to correctly stop seeding?, im using qbitorrent...
While anything over 1:1 is ideal, I think we can agree that setting it to at least 1:1 is better than setting it to 0 as u/Riusaki suggested. While it is the bare minimum, it’s not in any sense leeching to give back as much as much as you’ve received.
At work we somehow landed on the topic of how many holes a human has, which then evolved into a heated discussion on the classic question of how many holes does a straw have....
On the matter of the doughnut: If you make them at home, you’re almost always just rolling a cylinder and then making it a circle. I have never actually punched a hole out of a doughnut. That would mess up the toroidal shape.
“Soul” is just consciousness. Which many people seem to equate to the brain here.
There is 0 scientific evidence that consciousness has anything to do with our brains. Much to the contrary actually.
Consciousness truly is one of the biggest mysteries of life. We all experience it, but the more you observe it, the less you can find it.
It may feel at first as it’s a phenomena of the brain, of the mind. But soon after you start paying really close attention to it, you realize that consciousness is behind the mind. It’s underneath it.
It observes the mind. It observes everything. And that’s what it is. Perceiving. Aware of everything.
Its the only indivisible and irreducible thing in the universe that we ever found. Consciousness just is. It is the awareness in you. It is the awareness in everything.
When we crack consciousness, all these talks of “souls”, “god”, “atheism”, will seem just silly tbh.
There is 0 scientific evidence that consciousness has anything to do with our brains. Much to the contrary actually.
Source? Everything I’ve read on the topic suggests that it’s everything to do with the brain - damaged brain = no consciousness, even if the rest of the body fine.
Its the only indivisible and irreducible thing in the universe that we ever found. Consciousness just is.
It’s beyond worth it to just pay them the money. I kind of hate that they won, but this way I never see an ad no matter where I watch, and the creators I enjoy still get money out of my views. I would pay for more services if they had a No Ads option. (I might have gotten convinced to get Twitter Blue if it had 0 ads instead of just halving them…)
