Another article just came out today providing additional content on the Quantum Computing threat and it did reference the article that I had published. Glad that folks are working on this.

The NSA is worried about quantum computers. It warns that it “must act now” to ensure that encryption systems can’t be broken wide open by the new super-fast hardware.

In a document outlining common concerns about the effects that quantum computing may have on national security and encryption of sensitive data, the NSA warns that “public-key algorithms… are all vulnerable to attack by a sufficiently large quantum computer.”

Quantum computers can, theoretically, be so much faster because they take advantage of a quirk in quantum mechanics. While classical computers use bits in 0 or 1, quantum computers use “qubits” that can exist in 0, 1 or a superposition of the two. In turn, that allows it to work through possible solutions more quickly meaning they could crack encryption that normal computers can’t.

NSA states it must act now against the “Quantum Computing Threat” due to hackers can possess the technology. I wrote about this on Jan 10th. Glad someone finally is taking action.

The National Security Agency is worried that quantum computers will neutralize our best encryption – but doesn’t yet know what to do about that problem.

I do commend Sacramento for trying to put controls in place to reduce human trafficking; will it work?

What if banning smartphone encryption could stem the rising tide of human trafficking, a form of modern-day slavery from which perpetrators force victims to engage in commercial labor services or sex acts against their will?

Ex-NSA boss says FBI director is wrong on encryption

encryption

Encryption protects everyone’s communications, including terrorists. The FBI director wants to undermine that. The ex-NSA director says that’s a terrible idea.

The FBI director wants the keys to your private conversations on your smartphone to keep terrorists from plotting secret attacks.

But on Tuesday, the former head of the U.S. National Security Agency…

It’s an interesting idea, if not an original one. (it’s not) The problem is that, military grade encryption or not, it would be a single point of failure that could compromise your on AND offline security in one fell swoop.

Fugitive presidential candidate John McAfee is going back to his roots with a new security product that he calls “a f—ing game changer.”

(Phys.org)—” Spooky action at a distance,” Einstein’s famous, dismissive characterization of quantum entanglement, has long been established as a physical phenomenon, and researchers are keen to develop practical applications for entanglement including communication, encryption, and computing.

Quantum entanglement is a phenomenon in which the production or the interactions of a number of particles cannot be described independently of each other, and must instead be described in terms of the whole system’s quantum state.

Two recent experiments with entanglement have been reported in the Proceedings of the National Academy of Sciences, one proving that in photons can be preserved even in turbulent atmospheric conditions; the other demonstrating entanglement swapping between qubits over the 143 kilometers between the Canary Islands and Tenerife.

In one of my first articles for Lifeboat,* I provided an experimental methodology for demonstrating (or proving) the instantaneous ‘communication’ between quantum entangled particles. Even though changes to one particle can be provably demonstrated at its far away twin, the very strange experimental results suggested by quantum theory also demonstrate that you cannot use the simultaneity for any purpose. That is, you can provably pass information instantly, but you cannot study the ‘message’ (a change in state at the recipient), until such time as it could have been transmit by a classical radio wave.

Now, scientists have conducted an experiment proving that objects can instantaneously affect each other, regardless o the distance between them. [continue below]

[From The New York Times—Oct 21, 2015]:

Sorry Einstein.
Quantum Study Suggests ‘Spooky Action’ is Real

In a landmark study, scientists at Delft University of Technology in the Netherlands reported that they had conducted an experiment that they say proved one of the most fundamental claims of quantum theory — that objects separated by great distance can instantaneously affect each other’s behavior.

The finding is another blow to one of the bedrock principles of standard physics known as “locality,” which states that an object is directly influenced only by its immediate surroundings. The Delft study, published Wednesday in the journal Nature, lends further credence to an idea that Einstein famously rejected. He said quantum theory necessitated “spooky action at a distance,” and he refused to accept the notion that the universe could behave in such a strange and apparently random fashion.

A Game Changer in Quantum Computing:
The ingredients for superfast computers could be nearly in place. For the first time, researchers have demonstrated that two silicon transistors acting as quantum bits can perform a tiny calculation.

The advance represents the final physical component needed to realise the promise of super-powerful silicon quantum computers, which harness the science of the very small — the strange behaviour of subatomic particles — to solve computing challenges that are beyond the reach of even today’s fastest supercomputers. Potentially transforming fields like encryption and the search for new pharmaceuticals.

The significant advance, by a team at the University of New South Wales (UNSW) in Sydney appears today in the international journal Nature (“A two-qubit logic gate in silicon”).

“What we have is a game changer,” said team leader Andrew Dzurak, Scientia Professor and Director of the Australian National Fabrication Facility at UNSW.

“We’ve demonstrated a two-qubit logic gate — the central building block of a quantum computer — and, significantly, done it in silicon. Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs, which rely on more exotic technologies.

“This makes the building of a quantum computer much more feasible, since it is based on the same manufacturing technology as today’s computer industry,” he added.

Suggests a mechanism to be adopted for any
cryptocurrency that would alter the fee layer to
help fund a new public good.

From ABIS concept

In 2013, following a period of reflection and visioning, I imagined the possibility of completely altering the financial system as we know it. This vision, known as ABIS, will now see its first-ever implementation.

The implementation is now being issued in BCN’s GUI Wallet with the release of v. 1.0.8, where the transaction has been re-envisioned to allow the user new ways to explore the possibilities of transactions and realize greater giving potential, initially through two use cases involving unique forms of donations:

abis-donations

  1. Random donations — a percent of the sum depending on the available outputs. The user will be able to select the approximate desired amount for donation: from 0.1% to 10%. If there is a change input close enough to the target, it will be used as a donation.
  2. Donation mining — the user who is mining in pools from the GUI Wallet will be be able to specify donation address and percentage of donation mining shares (0–100%) that will be contributed for any donation.

This wallet is now available for anyone around the world to utilize and can aid those seeking to facilitate voluntary donation processes, and it is possible that more use cases for further microgiving possibilities may be added to the graphical wallet in the future.

Social Dimensions and Notions of the Transaction Have Limited Wallet Design Universally.

Most wallet software is designed with certain assumptions about what transactions are. If most in society have developed an assumption about what a transaction is, the manifestation of what our cryptocurrency wallets become (and the format in which the graphical user interfaces are developed to facilitate transactions) will tend to follow such a trend.

If a transaction (in which one sends, or transfers resources) remains limited notionally only as an exchange of currency for goods, services, or other currency, there is a problem in terms of the capacity which we are allowing ourselves to develop and enjoy from decentralized systems.

Certainly, this problem has not solely been in Bytecoin (BCN) but can be seen in any other cryptocurrency wallets as well, and of course, in all currency systems. Legacy systems — those which utilize fiat currencies and rely heavily upon central banks — simply do not have the flexibility to transmit very small amounts efficiently. Cryptocurrency systems are better poised to handle small amounts, but how they handle them will differ depending on the type of cryptocurrency being utilized.

Up to this point, some technical challenges exist which have kept cryptocurrency and wallet developers from tackling the issue, as mentioned in the BCN developer’s blog post, ‘Future of Slacktivism: How 1,000,000 Likes Can Save Lives’. Thus, cryptocurrency wallets do not yet emulate natural giving systems to the degree that they could.

The problem is that, around the globe, we have not yet re-envisioned the transaction to allow the user new ways to explore a transaction’s full potential and offer the option of greater giving potential. However, we now have the means to do so.

The initiative taken by the Bytecoin community to address this issue has resulted in software that is arguably the first of its kind ~ resistant to financial censorship (utilizing BCN’s installable desktop graphic wallet, which has anonymity preferences for transactions which the user can alter on a sliding scale ranging from greater to lesser anonymity), and now, allowing compassionate options for any user, which allow small donations to be sent and received anywhere in the world without any need for an intermediary.

Because the entire concept is fully voluntary there are really a nearly infinite range of choices, essentially limited only by the technology, fees, and network limitations. The user is contemplating who to provide a micro-donation to and at what level and at what threshold the microdonation(s) will be broadcast, based on their wallet settings.

And I hope that we would in this model of giving become more like the bees that share pollen as they bounce from flower to flower (indeed, the acronym of the concept, ABIS, stands for “Ants, Bees, Information, and Systems”).

An interesting commentary from recent events comes from the transcript of Pope Francis’s remarks to US Congress on Sept. 24, 2015:

‘We have the freedom needed to limit and direct technology’; ‘to devise intelligent ways of… developing and limiting our power’; and to put technology ‘at the service of another type of progress, one which is healthier, more human, more social, more integral’

We have the tools now at our disposal, and these tools are vital to have, but even more vital is having compassion and the desire to extend what we have to others, and to build systems in ways which do not rely upon coercion, violence, and the perils of institutional power.
