“That contemporary artists are exploring blockchain further suggests the technology has reached a level of cultural significance beyond bitcoin’s initial hype.”
Article repeats a lot of the knowns on QC such as bit v. Qubit; and finally provides some good info on pros and cons of Bitcoin and Lamport signatures technique with QC. However, the author didn’t seem to mention any of the work that D-Wave for example is doing with Block chaining. Also, I saw no mention of the work by Oxford on the logic gate which improve both the information processing performance and the security of information transmissions.
In a classical computer bits are used that can either be 0 or 1. In a quantum computer these bits are replaced with Qubits (quantum bits). These Qubits can be 0 or 1, or both at the same time. This is caused by a phenomenon in the quantum realm called superposition. At scales the size of an atom and small molecules, the spin of particles is not determined until it is observed. A pair of Qubits can be in any quantum superposition of 4 states, and three Qubits in any superposition of 8 states. In general, a quantum computer with n Qubits can be in a superposition of up to 2^n different states simultaneously (this compares to a normal computer that can only be in one of these 2^n states at any one time). Because of this, a quantum computer is able to perform computations at the same time, while classical computers perform computations one at a time.

I was asked this at Quora.com, where I answer questions under the pen name, ‘Ellery’. But the query deserves a companion question, and so I approached the reply by answering two questions.
You might have asked “Why was Bitcoin designed to have a cap?” But, instead, you asked “Why is the cap set at 21 million bitcoins”. Let’s explore both questions starting with the choice of a circulation cap…
Why set the cap at 21 million BTC?
The choice of a cap number is arbitrary and in fact, it could be 1 or it could be 1 hundred trillion. It makes no difference at all and it has no effect on the economy—even if Bitcoin were to be adopted as a currency all over the world. If it were set to 1 BTC, we would simply discuss nano-BTC instead of 1 BTC for amounts of about $650.
Last week I dipped my toes in the waters of the Lifeboat blog and shared a link about blockchain technology. If you haven’t heard about blockchain technology yet, you can read about it here, here, here, here, here…you get the picture. Blockchain has tons of potential, and appears to also attract hype and money. All which goes to say, there has been a lot of buzz about its social and economic potential. But there is another aspect of blockchain that deserves some futurist exploration, which is that it signals we live in Postnormal Times.
Postnormal Times (PNT) is a fantastic foresight concept that I will focus on in my upcoming Lifeboat posts. There is an underlying theory to it; Ziauddin Sardar explains the entire idea and how it fits into futures studies. Ziauddin Sardar with John Sweeney have expanded the work into a futurist method called The Three Tomorrows of Postnormal Times. It’s well worth reading up on if you enjoy a futurist approach to your work and studies.
I’m still a beginner, but essentially the idea is that we are now in time is a period best characterized as “postnormal,” meaning that the usual ways of solving problems and making progress have stopped working. Our go-to responses, based on all the previously reliable ways of being in and understanding the world are becoming irrelevant and dysfunctional. The simplest way to introduce Sardar’s concept is the three C’s: complexity, chaos and contradictions. These are the key characteristics of postnormal times which I will be exploring in my posts about technology and humanity. I believe the PNT perspective leads to some useful observations about the direction of society over the next decades.
Back to my blockchain example: the Raketa watch company is implementing blockchain in manufacturing, which will protect inventory from counterfeiting. This development signals PNT because it speaks to the complexity of globalized financial and consumer markets. In this case, so intricate as to require a new, high-tech, largely automated and seemingly fail-proof technology. PNT is evident when previous methods of running a company are no longer sound. Enter blockchain to navigate this new business condition.

In Bitcoin’s early years computer scientists and early adopters were running the show. Now, a new community of academics, entrepreneurs, and economists, are working with cryptocurrencies and blockchain to bring the technology to a new set of diverse applications.
From building peer-to-peer networks for secure data computation and storage to decentralized content management systems that give patients access to health-care records across hospital databases, blockchain and digital currencies are starting to rewrite the rules of the 21st century transaction.

“In an obscure corner of the internet, an anonymous person or persons published a math paper — the “Bitcoin white paper” — that solved a problem that had until then stumped computer scientists: how to create digital money without any trusted parties.”
Anyone who has heard of Bitcoin knows that it is built on a mechanism called The Blockchain. Most of us who follow the topic are also aware that Bitcoin and the blockchain were unveiled—together—in a whitepaper by a mysterious developer, under the pseudonym Satoshi Nakamoto.
That was eight years ago. Bitcoin is still the granddaddy of all blockchain-based networks, and most of the others deal with alternate payment coins of one type or another. Since Bitcoin is king, the others are collectively referred to as ‘Altcoins’.
But the blockchain can power so much more than coins and payments. And so—as you might expect—investors are paying lots of attention to blockchain startups or blockchain integration into existing services. Not just for payments, but for everything under the sun.
Think of Bitcoin as a product and the blockchain as a clever network architecture that enables Bitcoin and a great many future products and institutions to do more things—or to do these things better, cheaper, more robust and more 
secure than products and institutions built upon legacy architectures.
