Omololu Akin-Ojo was always reluctant to go to the United States. “I felt I could do a lot of things in Africa,” he told me in his office at the new East African Institute for Fundamental Research (EAIFR) in Kigali, Rwanda. “Unfortunately, I was wrong.”

As a university student in his home country of Nigeria in the late 1990s, Akin-Ojo learned to write computer code by hand, without ever having the chance to put the code into a computer. Aware of these limitations, his father, a physicist, encouraged him to apply to doctoral programs abroad. While studying condensed matter physics at the University of Delaware, Akin-Ojo recognized the gulf in teaching and in research opportunities between Nigeria and the U.S.

He realized then that he wanted to stem the brain drain of Africa’s brightest minds. Although he spent the next 14 years working in the U.S. and Europe, he said, “I always knew I was coming back to Africa.” He chose to specialize in theoretical physics, so that the lack of experimental equipment in Nigeria wouldn’t hinder his research when he returned.

“The best-kept secret in quantum computing.” That’s what Cambridge Quantum Computing (CQC) CEO Ilyas Khan called Honeywell’s efforts in building the world’s most powerful quantum computer. In a race where most of the major players are vying for attention, Honeywell has quietly worked on its efforts for the last few years (and under strict NDA’s, it seems). But today, the company announced a major breakthrough that it claims will allow it to launch the world’s most powerful quantum computer within the next three months.

In addition, Honeywell also today announced that it has made strategic investments in CQC and Zapata Computing, both of which focus on the software side of quantum computing. The company has also partnered with JPMorgan Chase to develop quantum algorithms using Honeywell’s quantum computer. The company also recently announced a partnership with Microsoft.

Many of you know the sad news that theoretical physicist & mathematician Freeman Dyson has passed away, so in celebration of his life and achievements, Anders Sandberg (Future of Humanity Institute) discusses Freeman Dyson’s influence on himself and others — How might advanced alien civilizations develop (and indeed perhaps our own)?
We discuss strategies for harvesting energy — star engulfing Dyson Spheres or Swarms, black hole swallowing tungsten dyson super-swarms and other galactic megastructures, we also discuss Kardashev scale civilizations (Kardashev was another great mind who we lost recently), reversible computing, birthing ideal universes to live in, Meinong’s jungle, ‘eschatological engineering’, the aestivation hypothesis, and how all this may inform strategies for thinking about the Fermi Paradox and what this might suggest about the likelihood of our civilization avoiding oblivion. though Anders is more optimistic than some about our chances of survival…

Anders Sandberg (Future of Humanity Institute in Oxford) is a seminal transhumanist thinker from way back who has contributed a vast amount of mind blowing material to futurology & philosophy in general. https://en.wikipedia.org/wiki/Anders_Sandberg

Honeywell, the same company that might make your humidifier or home security system, is unveiling a powerful quantum computer that will be available to the public.

If it works, they would be able to input quantum information into one “black hole” circuit, which would scramble, then consume it. After a little while, that information would pop out of the second circuit, already unscrambled and decrypted. That sets it apart from existing quantum teleportation techniques, Quanta reports, as transmitted information emerges still fully scrambled and then needs to be decrypted, making the process take longer and be less accurate as an error-prone quantum computer tries to recreate the original message.

While the idea of entangled black holes and wormholes conjures sci-fi notions of intrepid explorers warping throughout the cosmos, that’s not quite what’s happening here.

Rather, it’s an evocative way to improve quantum computing technology. Recreating and entangling the bizarre properties of black holes, University of California, Berkely researcher Norman Yao told Quanta, would “allow teleportation on the fastest possible timescale.”

Circa 2019 the quantum computer could control time.

A group of scientists from the RIKEN Center for Emergent Matter Science in Japan has succeeded in taking repeated measurements of the spin of an electron in a silicon quantum dot (QD) without changing its spin in the process. This type of “non-demolition” measurement is important for creating quantum computers that are fault-tolerant. Quantum computers would make it easier to perform certain classes of calculations such as many-body problems, which are extremely difficult and time-consuming for conventional computers. Essentially, the involve measuring a quantum value that is never in a single state like a conventional transistor, but instead exists as a “superimposed state”—in the same way that Schrodinger’s famous cat cannot be said to be alive or dead until it is observed. Using such systems, it is possible to conduct calculations with a qubit that is a superimposition of two values, and then determine statistically what the correct result is. Quantum computers that use single electron spins in silicon QDs are seen as attractive due to their potential scalability and because silicon is already widely used in electronics technology.

The key difficulty with developing quantum computers, however, is that they are very sensitive to external noise, making error correction critical. So far, researchers have succeeded in developing single electron spins in silicon QDs with a long information retention time and high-precision quantum operation, but quantum non-demolition measurement—a key to effective error correction—has proven elusive. The conventional method for reading out single electron spins in silicon is to convert the spins into charges that can be rapidly detected, but unfortunately, the electron spin is affected by the detection process.

Now, in research published in Nature Communications, the RIKEN team has achieved such non-demolition measurement. The key insight that allowed the group to make the advance was to use the Ising type interaction model—a model of ferromagnetism that looks at how the electron spins of neighboring atoms become aligned, leading to the formation of ferromagnetism in the entire lattice. Essentially, they were able to transfer the spin information—up or down—of an electron in a QD to another electron in the neighboring QD using the Ising type interaction in a magnetic field, and then could measure the spin of the neighbor using the conventional method, so that they could leave the original spin unaffected, and could carry out repeated and rapid measurements of the neighbor.

Scientists uncovered a new state of matter that could lead us to many exciting new forms of quantum computing and teleportation.

When you see an unconscious patient in a movie, you sometimes see their thoughts onscreen (like in The 9th Life of Louis Drax, above) or at least hear a voiceover.

That may not entirely stay in science fiction. Adrian Owen, neuroscientist and Professor of Cognitive Neuroscience and Imaging at the University of Western Ontario, Canada, and his research team are using brain-computer interfaces with advanced technology to get answers directly from people who can’t answer for themselves any other way. Any critical decisions for patients unable to communicate are usually made for them.
