Since the 1960s the power of computers has kept growing exponentially which made our computers smaller and faster at the same time.Computer parts are approaching the size of an atom that’s why this process is about to meet its physical limits.
In classical computing, a single piece of information is a bit. It can exist in either state 1 or 0.Quantum computers use qubits, which can also be set to one of two values: 1 or 0.But qubits have their unique property that sounds like "A qubit could be at any proportion of 0 and 1 at once”. This is called the superposition. But as soon as you want to get its value, the qubit has to decide to be either „0” or „1”.
This means that while being unobserved the qubit is in the superposition of probabilities for 0 and 1 and you can’t predict which it will be but when you want to retrieve its value, qubit should collapse into 1 or 0.
For example, 5 classical bits can be in 1 of 25 possible states at a time while five qubits in a superposition can be in all of those 32 combinations at once.This number grows exponentially with each new bit.This means that a computer using these bits can store much more information using less energy than a normal computer.
Quantum computers operate on completely different principles to existing computers.This makes them incredibly efficient for particular mathematical problems.
Let’s take a look at the database search engine.In order to find some value in the database store, a normal computer may test every single one of its entries.While the quantum computer may do it in only the square root of that time.This could be crucial for some huge databases.
Quantum computers can also be used to model complicated chemistry reactions, a task that conventional supercomputers are not good at.Probably quantum simulations will be used to design entirely new molecules for use in medicine.
On the flip side, quantum computers could be applied to ruin IT security.Taking under consideration the fact that quantum computers can easily find very large prime numbers, they could easily crack your private secret key to decode encrypted information as well.While it would literally take years for normal computers.This could make all our private information not actually private anymore(of course if it’s not already).
Questions:
- Would the quantum computer be the next step of the computer era?
- Would you like to have the quantum computer at home? What for?
- Does the invention of quantum computers mean that one day we will have quantum smartphones? Could you give an example of the usage of such a device?

I personally cannot think of any situation which might require usage of machine of such high computational power. I don't need quantum PC or quantum smartphone for my daily routine tasks. For scientists who deal with Big Data and perform some resource-heavy operation using computers that might take decades to finish processing this technology will be a great time-saver but for regular users, it's overkill and simple waste of money.
Right now, I would like to wait for an affordable quantum computer available in store, so I could check its available features and decide if want one in my home ;)
I don't think that quantum computing allows us to create an operating system the way we know it now. So if there will be quantum smartphones, they will look completely different than now.
I cannot think of any possible use for quantum smartphones. I guess the battery life could get improved on one hand, seeing that the storage would be much more effective. On the other hand, the processed data would also be of enhanced size and that could impact the battery life greatly. I guess they would have to think of some new features for phones - like advanced voice assistant that does many of the things for you, and has a memory and "personality" that adapts during usage, may seem like one option for quantum technology.
2. I don't think I will need such equipment at home, I don't think I need it at all. However, as far as the work is concerned, I would be very happy to ask for such equipment when using a very large database.
3. This is very possible because smartphones are similar in design to computers. However, this will not have the same impact as quantum computers
Who wouldn't? I could play any game without any lags on the highest settings!
Yeah, that might happen, but it is so distant future ... I can't even imagine the usage of such devices.
Quantum computers will probably become faster per step, but so will conventional computers. I would not count on quantum computers being faster per step than regular computers in the future, unless some major physics discoveries are made. However, for tasks where they win by the number of steps, quantum computers could be useful if they can be built in more-than toy sizes. Unfortunately, their fragility and high error rates make it difficult to leverage these advantages today.
Yes, I would like to have the quantum computer but it will probably be too expensive for me. I want to send email on that, why not? :P
About last question? Yes, I hope that I will se quantum smartphone in my life. World is growing very rapidly and it can be real. It's hard to say about usage.
Personally, I think not. Currently, computers are so strong that you don't need more power to do the things that I do. Although if I had a chance with desire, I would like to have such a machine.
Unfortunately, I have no idea. I can guess but it's also heavy here, because I don't know exactly this technology and what it can do.
I don't know, article is don't answer this question.
Would you like to have the quantum computer at home? What for?
No, I don't.
Does the invention of quantum computers mean that one day we will have quantum smartphones? Could you give an example of the usage of such a device?
I don't know, article is don't answer this question.
The main problem of the post - is a lack of info about technologies needed to achieve this performance, and it cost.
If they would be cheap enough I would like to have one in my home to work with. And to be sure, I'm capable of knowing how to make anything with them.
Well, maybe the future will bring to us quantum smartphones... But it will be still used as a normal smartphones - to call others, text with them, play games in bus, read books, view sweet kitties videos in the Internet...
Well, it is not like it is something new out there - we have quantum computers for a while, so I dare to say that we are living in the era you are describing.
2. Would you like to have the quantum computer at home? What for?
As far as I know, these computers are great at solving particular problems, but they are not designed to work like a standard I/O PC to listen on user events and respond accordingly. However, if they could work properly as a home PC I would definitely like to have one. I would use it great power and efficiency to dig some Bitcoins and play UHD games.
3. Does the invention of quantum computers mean that one day we will have quantum smartphones? Could you give an example of the usage of such a device?
Well, having ultra spec PC or mobile is different than having a quantum one, right? It is just designed to do something else, so I can't imagine a real purpose for a quantum smartphone.. Maybe as one of many clusters in a huge quantum PC.
Your article is based on existing knowledge, so we have some quantum computers already, but I if you refer to the personal computers sector, I don't think we will need it in the near future, unless our security is compromised.
I can't think of any reasonable use at moment.
Sound completely unnecessary, but again, I'm no expert in quantum computing.
In my opinion yes, but people could still find something better, but the idea of quantum computer will be still alive with few years ahead.
Would you like to have the quantum computer at home? What for?
Someday maybe we will be having quantum computer on the wrist because they will be more energy-efficient and battery will last longer. Right now I would like to have that computer to make research on them.
I wouldn't want to have a quantum computer at home, at least not as for now. The conditions needed for them to be effective are pretty insane as well as I probably wouldn't find any use for it. For anyone who is interested in the topic, I recommend to watch Linus Tech Tips video about them.
Would quantum smartphones ever be a thing? I wouldn't say no, looking at the improvements made by the regular computers over the last decades. What would be their purpose? I don't have any idea, honestly.
If the prize will match the quality and performance I will consider buying - I'm always happy to use something new, something that can be extrordinary.
Of course that may happen, smartphones are similar in design to computers. But for now, I don't have example if the usage of this device
Would I like to have it at home? I’m not sure that I need it now due to I'm not using the full power of my current computing resources. But due to needs of software also rising I believe it can also need a better hardware. At least for some professional programs for modeling, graphics, simulations it can be used also on private PCs. Maybe researchers which currently calculated on supercomputers some enthusiasts will be able to d at home on PC.
Hmm, for it’s hard to say is quantum computing will be ever applied for smartphones as I think even now smartphones are much more powerful than we actually need.
I would not like to have one from what i know it would be more of an inconvenience than help in any tasks i would need its help.
No, i hardly can see quantum computers as a staple part of our homes not even talking about miniaturizing it to a handheld devices size. One thing i can see about quantum computer is future regarding cloud computing, i think that maybe those computers might be a core of cloud computing of the future and removing computing part of our pc's and phones entirely.
Absolutely, I hope that this computers are going to be used for scientific purposes.
Would you like to have the quantum computer at home? What for?
Actually I think there is no need of having so powerful device for personal use. I think nowadays most people don't exploit even half of performance of their devices.
Does the invention of quantum computers mean that one day we will have quantum smartphones? Could you give an example of the usage of such a device?
Maybe but I can't find any sensible purpose for quantum smartphone for now
For me I haven't got any idea for what I can use that kind of computer. Maybe for very realistic video games? That's the only thing I can imagine to use that big calculate power.
Quantum smartphones are funny idea for me. I'm not able to find any possibility to improve smartphones' usage that could be improved with more power. Of course it could be the same like with old fashioned mobile phones and smartphones: 30 years ago nobody suppose to comment on online blogs using their mobile phones. So for our descendants who will use that quantumphones far more things which you can do with your mobile will be obvious.
advantage over traditional computing in cryptographic hashing,
thus no significant advantage in either mining or attacking.
They aren’t necessarily just more powerful versions of the
computers we already have — they are at very specific mathematical calculations.
Of course, I would like to have one of these computers at home but sadly I think that this era will not occurs in my life.
It is more than obvious that if quantum computers get real, it will be miniaturized someday and get to our pockets. I think that nowadays smartphones have enough power to cover our current needs.
"With Great Power Comes Great Responsibility" - I think this quote summarises the quantum computing power. Unfortunately, there will be some individuals in our society who will use this technology in a wrong way, because of this we will need to find a way how to defend them.
Discovery of quantum power will spread across all devices we use today. I hope in someday we will be able to carry current super gaming pc in our pockets and need to connect it to extra monitor to play even most power required games.
If that kind of computers work good enough as home PC - why not. If the price is matching power/effinency, of course I would like to try it, especially with some 4k gaming.
I can’t really imagine the usage of quantum smartphone…
