We’re on a roll with QC.
The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. The research advance, using a 3-dimensional array of atoms in quantum states called quantum bits—or qubits—was made by David S. Weiss, professor of physics at Penn State University, and three students on his lab team. He said “Our result is one of the many important developments that still are needed on the way to achieving quantum computers that will be useful for doing computations that are impossible to do today, with applications in cryptography for electronic data security and other computing-intensive fields.”
The new technique uses both laser light and microwaves to precisely control the switching of selected individual qubits from one quantum state to another without altering the states of the other atoms in the cubic array. The new technique demonstrates the potential use of atoms as the building blocks of circuits in future quantum computers.
The scientists invented an innovative way to arrange and precisely control the qubits, which are necessary for doing calculations in a quantum computer. “Our paper demonstrates that this novel approach is a precise, accurate, and efficient way to control large ensembles of qubits for quantum computing,” Weiss said.

We now have a way to do tracibility in QC.

Chinese scientists won a major victory recently, by proving that the Majorana fermion — a particle we’ve found tantalizing hints of for years — genuinely exists. This discovery has huge implications for quantum computing, and it might change the world. But how?
A Majorana fermion is weird even by the standards of quantum physics. If you remember your high school physics, you remember that atomic particles like protons and electrons have a charge, positive or negative. The Majorana fermion, however, doesn’t have a charge, which allows it to be matter and anti-matter at the same time. Yes, that is incredibly confusing, even to quantum physicists, and they’re still arguing over how that even works.
This video is worthless. I hear a person who is out of touch with the QC work and isn’t even aware all of the work going on. Frankly, QC is being worked on by big tech (Amazon, Google, Microsoft, D-Wave, IBM), governmental labs and incubators, limited set of start ups who are also (in many cases tied to big tech), and university research labs. Therefore, I don’t really find this soapbox video that informative as well as not in touch with where QC is today. It appears to me that this guy has sour grapes over not being engaged.
At least if you’re going to get on a soapbox and try to talk about QC like you’re somehow an expert or informed; at least make sure you know what has been shown, reported, and in development currently that has been publically announced so that you don’t look like you’re an un-informed consultant doing a superficial presentation and didn’t even bother doing the due diligence 1st. Otherwise, you just discredited your VC/ firm to the public and to those working on QC.

One of the key insights that legendary physicist and Nobel Prize laureate Richard Feynman had was that quantum mechanics (the branch of physics that deals with subatomic particles, uncertainty principle, and many other concepts beyond classic physics) is just way too complicated to simulate using traditional computers.
Nature, of course, can handle these complex calculations — computers however can’t do those same calculations (or would take a prohibitively long time and amount of resources to do so). But this isn’t just about being able to do more with computers in a faster (or smaller) way: It’s about solving problems that we couldn’t solve with traditional computers; it’s about a difference of kind not just degree.

Quantum computing makes small, but significant progress.
A high-energy physics experiment has been completed using a simple quantum device that, if scaled up, could potentially greatly outperform a conventional computer.
Physicists from the Institute for Quantum Optics and Quantum Information at the Austrian Academy of Sciences have used the quantum computer to simulate the spontaneous creation of particle-antiparticle pairs.
It would seem that no one’s immune from the effects imposed by our increasingly sophisticated artificial intelligence and robotics — not even doctors. As research from Indiana University has revealed, a new computer program is doing a better job than doctors when it comes to both diagnosing and treating health conditions — and by a significant margin.
The system, which uses decision making processes similar to the Jeopardy-bot, Watson, was recently given the task of analyzing and predicting the health outcomes of 500 real individuals. After plugging in the relevant data — which mostly had to do with clinical depression and chronic diseases like high blood pressure and diabetes — researchers Kris Hauser and Casey Bennett compared the outcomes to the simulated treatment prescriptions.

A transistor, conceived of in digital terms, has two states: on and off, which can represent the 1s and 0s of binary arithmetic.
But in analog terms, the transistor has an infinite number of states, which could, in principle, represent an infinite range of mathematical values. Digital computing, for all its advantages, leaves most of transistors’ informational capacity on the table.
In recent years, analog computers have proven to be much more efficient at simulating biological systems than digital computers. But existing analog computers have to be programmed by hand, a complex process that would be prohibitively time consuming for large-scale simulations.

Power consumption is one of the biggest reasons why you haven’t seen a brain-like computer beyond the lab: the artificial synapses you’d need tend to draw much more power than the real thing. Thankfully, realistic energy use is no longer an unattainable dream. Researchers have built nanowire synapses that consume just 1.23 femtojoules of power — for reference, a real neuron uses 10 femtojoules. They achieve that extremely low demand by using a wrap of two organic materials to release and trap ions, much like real nerve fibers.
There’s a lot of work to be done before this is practical. The scientists want to shrink their nanowires down from 200 nanometers thick to a few dozen, and they’d need new 3D printing techniques to create structures that more closely imitate real brains. Nonetheless, the concept of computers with brain-level complexity is that much more realistic — the team tells Scientific American that it could see applications in everything from smarter robots and self-driving cars through to advanced medical diagnosis.

IBM and marketing company The Drum just announced that the AI Watson was able to edit an entire magazine on its own. This showcases the computing potential that AI has in an increasing number of fields.
IBM and a marketing company called The Drum just announced that the AI system known as Watson was able to edit an entire magazine on its own. Yep, an AI magazine editor.
According to a statement released via The Drum, the magazine edited by Watson contains different features that shows Watson’s capabilities. It has different analytical functions, as well as skills necessary to assist modern-day marketers. Also, Watson has been programmed to have the capacity to answer a series of questions about David Olgivy, the “advertising legend,” and was able to give some predictions for the winners of this year’s Cannes Lions awards.
