Thanks to quantum computing, computers are about to become unfathomably powerful. Instead of relying on transistors and binary signals as is the case with current computers, quantum computers use microwaves and quantum particles to explore multiple calculations simultaneously. This allows quantum computers to be blazingly fast. One prototype quantum computer proved 100 million times faster than its normal counterparts, and these speeds have numerous applications. Likewise, quantum technologies will also be applied more broadly than in just computers, reinventing many devices and technical standards.

Quantum computers will be able to simulate previously impossibly large chemical reactions, leading to new materials and medicines. Intensely precise sensors and clocks will enable disruption-proof navigational technologies, radars, and more. Previously challenging optimization problems, such as analyzing complex sets of variables to find the best asset allocation for an investment portfolio, will be within the realm of feasibility. The first country to successfully commercialize quantum technologies will gain a huge first mover advantage, both in quantum devices and in all of the discoveries the technology will unlock.

I, for one, welcome our quantum AI overlords.

I just hope I'm retired by the time this really takes off.  I'm too old and tired to learn new technologies like this.

Chinese.  Definitely gonna be the Chinese.  

Why would you say this ?  Their entire technological world is reverse engineering others inventions.  They require companies wishing to do business in China  to partner with Chinese companies to help facilitate their theft of intellectual property.

They have to buy aircraft carriers from Russia... Russia !!

 

 

Quantum computing's strength - parallel evaluation of numerous permutations/variables - make it a natural fit for breaking encryption.  When quantum computing gets beyond the NSA and well financed tech labs like the Google-NASA one mentioned in the article, it's going to have huge (negative) implications for online commerce and communication.

who says they haven't already had those implications?

I'm talking about encryption busting quantum computing in the hands of Joe Public, not just the NSA and a few very well funded labs somewhere.  When encryption can't be trusted, ecommerce will die.  More than that - ACH payment systems, credit/debit cards, etc. will no longer be secure.  Credit card skimming at gas pumps will be a humorous anecdote in the annals of history.  Ironically, this might help kill the current push towards a cashless society, but at a very heavy price as it also means no more secure communications (a tremendous boon to the surveillance state, a problem for national security everywhere).

Will these work for mining BTC?

Yes, yes they will but they will work so well they will render the blockchain obsolete.

It might be wise to invest in currencies that use a quantum resistant blockchain.

The most well known and developed application of quantum cryptography is quantum key distribution (QKD), which is the process of using quantum communication to establish a shared key between two parties (Alice and Bob, for example) without a third party (Eve) learning anything about that key, even if Eve can eavesdrop on all communication between Alice and Bob. If Eve tries to learn information about the key being established, key establishment will fail causing Alice and Bob to notice. Once the key is established, it is then typically used for encrypted communication using classical techniques. For instance, the exchanged key could be used for symmetric cryptography.

The security of quantum key distribution can be proven mathematically without imposing any restrictions on the abilities of an eavesdropper, something not possible with classical key distribution. This is usually described as "unconditional security", although there are some minimal assumptions required, including that the laws of quantum mechanics apply and that Alice and Bob are able to authenticate each other, i.e. Eve should not be able to impersonate Alice or Bob as otherwise a man-in-the-middle attack would be possible.

One aspect of quantum key distribution is that it is secure against quantum computers. Its strength does not depend on mathematical complexity, like post-quantum cryptography, but on physical principles.
