There is already news out in reddit that the Litecoin developers headed none other than Charlie Lee will start R&D on the cryptocurrency's upgrades. Among them were confidential transactions, dynamic block sizes and a quantum resistant cryptography method. Maybe the Bitcoin core developers might learn a thing or two from the LTC developers and integrate their research and progress into Bitcoin's protocol.
Why are people saying that quantum computers are still a thing of the future? Aren't they already here and only getting better? http://www.sciencealert.com/google-s-quantum-computer-is-100-million-times-faster-than-your-laptop And, https://en.wikipedia.org/wiki/D-Wave_Systems
Is the future now?
Is the future now?
I believe quantum computers are a problem for cryptocurrency the future, but I think it will still take a long time for this to happen. Maybe decades or even more.
in regards to quantum computing people need to get their heads out of the sci-fi section and into reality.
quantum/d-wave (once you wash away the foolish buzzwords of it) is simple. instead of a micro transistor having 2 options(binary).. it has 4.
and here is where the magic evaporates.
in binary
imagine 0 volts is 0(false/off/no/negative/dark)
imagine 1 volt is 1(true/on/yes/positive/light)
now.. imagine instead of 2 options. there are four options 0 1 2 3
imagine 0 volts is 0(false/off/no)
imagine 0.33 volts is 1(not false not true/not off not on/not no not yes)
imagine 0.66 volts is 2(false and true/off and on/ no and yes)
imagine 1 volt is 3(true/on/yes)
now imagine all this shit about trans-dimensional space, time travel and parallel states as just bait, to keep the very simple logical process from being revealed(avoid corporate competition by not revealing the simple secret sauce ingredient) of micro transistors with 4 options instead of 2
the whole "new states of both on and off" is just wishy washy wording, meant only for sci-fi movies because its not actually any magic of
binary "off / on"
dwave "off / not off not on/ off AND on / on"
as these are just attributes(names) and those 2 new options in the middle can mean anything you want it to mean.
yes / maybe / not sure / no
yes / sometimes / not often / no
night / morning / afternoon / evening
all you need to know is a micro transistor in a Dwave has 4 options instead of 2.
an 8 bit dwave 'byte' allows for 65,536 possibles(4^8) instead of 8 bit binary 'byte' allowing for 256 possibles(2^8)
this allow a hex to be stored using just two bits instead of 4bits
meaning you can store FFFF(33333333) in one dwave byte instead of just FF in a binary byte(11111111)
its utility for compression and speed improvement of data is limited. but its utility in logic problems opens up immensely.
its just going to take time for then to think up some logic problems that can utilise the 2 extra options.
if you want to think of it like a switch.
bright light on / romantic dim setting / movie-gaming dim setting / light off.
if your light switch in your living room or den only has on or off. your missing out on 'mood lighting'. get yourself a dimmer switch
and then spend some time thinking about what you will use the two new dimmer settings for, but be warned they are not for trans-dimensional wormhole jumping or parallel universe hopping

I agree with everything accept the wormhole jumping and trans-dimensional universe hopping. The way I understand it is that they are especially suited for such applications; in fact, that's the primary cause of the Mandela Effect. <---Kidding
Tinfoil hats aside: Considering the 4 different states, I take it that boolean logic wouldn't be effective....but once a more established "fuzzy" logic is standardized, do you think the bitcoin community has it in them to re-vamp the code in a timely and diplomatic manner?

lol no one said quantum computers is going to take you to different universes. this is about the processing power of the computers being greater and how someone can use that bruteforce a privatekey.~~~ but be warned they are not for transdimensional wormhole jumping or parallel universe hopping
im talking more about the comedy of the D-wave CEO doing TED talks and magazine interviews trying to sell d-wave using words fit only for a sci-fi novel

In the future it could have an impact. If SHA encryption is broken for example. However bitcoin would be the least of our worries if that happened. Much of the internet would be vulnerable.
Nexus is the only coin in development with the foresight to see the back lash QC will have on current block chain tech.
Pretry interesting check em out
EDIT: It is also true that if we saw this coming we could switch to another encryption scheme.

agreed, the amount of resources that go into funding and operating a quantum computer is extremely extremely high. i really doubt anyone would be using such amazing processing power to brute force a bitcoin private key. Why are people saying that quantum computers are still a thing of the future?
Because they are only using a small amount of qubits (latest model 1152) at the moment. These computers are only very fast in certain types of operations, and may even be slower than traditional computers in others. Is the future now?
I'd say not yet.Quote
“You need to read the fine print,” says Matthias Troyer of the Swiss Federal Institute of Technology in Zurich. “This is 108 times faster than some specific classical algorithm on problems designed to be very hard for that algorithm but easy for D-Wave.” In other words, the D-Wave had a massive home advantage.
Better versions of the simulated annealing algorithm can reduce this advantage to just 100 times faster, says Troyer, while other more complex algorithms running on an ordinary PC can beat D-Wave entirely. “A claim of ’108 speedup’ is thus very misleading,” he says.

You can probably finder more/better information if you spend more time researching into it.
I agree. If I spent more time looking at all the specs, I would be more aware....and I have spent some time looking into it. But, my point was that there are already quantum computers in use and pre-orders are already filled for the next generation machines....Quantum computers are here now and the number of qubits they're achieving each year is growing at a pace that rivals Moore's Law....I don't think bitcoin needs to be overly concerned because the network will adjust.

This is the part so many people neglect to realize. If quantum computing made any real impact on things like encryption, we'd have more processing power to create a better, more secure one. And since BTC is open source, that is a quick and easy solution. At the same time, however, it would disable all current ASICs, and I do believe most altcoins would be susceptible (as the majority don't even follow current development).
Bitcoin modified to use a quantum cryptography algorithm would probably make it even more secure. Quantum techniques could strengthen a modified Bitcoin's security, not destroy it. There is a paper at SANS discussing quantum cryptography which concludes that "quantum techniques should meet the encryption needs of users, perhaps indefinitely".
Quantum Encryption - A Means to Perfect Security?
It gives three reasons that make quantum cryptography uncrackable in the paragraph below.
Quote
Quantum cryptography is thought to be secure for three main reasons (Lo). One, the quantum no-cloning theorem states that an unknown quantum state cannot be cloned. Theoretically, messages sent using quantum cryptography would be in an unknown quantum state, so they could not be copied and sent on. Two, in a quantum system, which can be in one of two states, any attempt to measure the quantum state will disturb the system. A quantum message that is intercepted and read by an eavesdropper will become garbled and useless to the intended recipient of the message. Three, the effects produced by measuring a quantum property are irreversible, which means an eavesdropper cannot “put back” a quantum message to its original state. These three properties provide the power of quantum cryptography. No amount of effort or genius can alter the fact that observing a quantum property irrevocably alters the object being observed.
It also adds that the first prototype demonstrating encrypting and decrypting quantum messages was invented in 1989, so quantum cryptography is no longer just theoretical.
Quote
Public key cryptography was invented in the 1970s by Diffie, Hellman and Merkle. It differed from previous encryption systems in that the groups sending messages did not have to agree on a key beforehand. The encryption key is in the public domain, so anyone can encrypt a message, while the related decryption key is held privately so that one person or a trusted group of people are the only ones able to decrypt the message. In 1989, the first fully working prototype of an instrument that encrypted and decrypted quantum messages was produced at the IBM Thomas Watson Research Center. In this case, the information was transmitted over a distance of only a few inches and the transmission rate was very low (Dwyer).
Quantum computing is definitely a matter of serious concern.
It is said that it will break the block chain mechanism.
I think it will take more time to come to reality

Why do people always ask the same questions over and over again, without even spending 5 seconds trying to search for the answers themselves? This topic was beaten to death, and here are some examples:

Quantum Computing breaking bitcoin is a myth, nothing more.
No, actually it is not. Quantum computers could break ECSDA to being with.
We will have another Y2K event, where all secure sites and technologies using the current algorithms need to upgrade to something
stronger, this includes Bitcoin. I am not saying that there will not be a window period, where there will be vulnerabilities, but whomever
gets to develop Quantum computers first, will give us enough warning to upgrade. { They will boast about their accomplishment, way in
advance }

Quantum Computing breaking bitcoin is a myth, nothing more. Do you think that in times when we will see real,working quantum computer bitcoin network will be still running on the same old 'engine'?
What is most likely scenario - bitcoin network will be upgraded to match current technological progress. Plus - Bitcoin is not the primary target in case we we will have suddenly QC - traditional banking is.
They are using encryption, old school networking and all these features will make them more susceptible to attacks that bitcoin network ever will.

So it just came to me. Quantum computers are pretty in the near future and it will expand and change prety much everything we see now, but how will quantum computing impact bitcoin?
I have read a post from theymos and from an analyze bitcoin is protected from these quantum computers for few or more years. I think until then bitcoin will be prepared from these quantum computers.
i agree with everyone that suggest that quantum computing does take a very long time to become a reality,theoretically it is based on light and photons and the success of it depends upon how they succeed in the interaction of light and photons and their precision, hope they will succeed in creating a quantum logic gate in a few years .
