Interesting read on history’s Quantum journey.

Since the dawn of the new millennium and in this slow and daunting journey through the first 15 years of the century, “quantum theory” has been a great aggregate explaining all that is possible. There have been a number of people who speak about the esoteric in terms of quantum entanglement as the halfway point between science and magic. It has been implied and critically so, that quantum mechanics are somehow proof or a good reason to say that anything can happen and it usually does.

However, it may be said accurately that rather, quantum possibilities should really be about probabilities which can be analyzed on a sub atomic level.

However, with scientific critique and intricate word salad aside, the world and the space that surrounds it is infinite and thus, it is counter-intuitive to say there are only finite possibilities or probabilities in the infinite universe.

Hmmm; sure hope others catch up soon.

China has launched a satellite that it claims has teleportation-like quantum communication capabilities.

While humanity may be a long way from “beaming” humans aboard a starship, scientists have made major strides in teleporting information. In March, German physicists made major advances in “quantum teleportation,” transmitting data across physical distance without a time delay.

# Physics # Theories – This New Equation Could Unite The Two Biggest Theories in Physics : In a recent paper, a Stanford theoretical physicist develops a new equation, one which indicates that the key to finally connecting general relativity and quantum mechanics is found in bizarre spacetime tunnels called wormholes.

One of the most stubborn problems in physics today is the fact that our two best theories to explain the Universe – general relativity and quantum mechanics – function perfectly well on their own, but as soon as you try to combine them, the maths just doesn’t work out.

But a Stanford theoretical physicist has just come up with a new equation that suggests the key to finally connecting the two could be found in bizarre spacetime tunnels called wormholes.

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied concepts of classical holography to the world of quantum phenomena. A new measurement technique has enabled them to register the first-ever hologram of a single light particle, thereby shedding new light on the foundations of quantum mechanics.

Scientists at the Faculty of Physics, University of Warsaw, have created the first ever hologram of a single light particle. The spectacular experiment was reported in the prestigious journal Nature Photonics.The successful registering of the hologram of a single photon heralds a new era of quantum holography, which offers a whole new perspective on quantum phenomena.

“We performed a relatively simple experiment to measure and view something incredibly difficult to observe: the shape of wavefronts of a single photon,” says Dr. Radoslaw Chrapkiewicz.

The human brain has Quantum consciousness according to China. Why a cogitative thinking system that truly mimics the human brain will require QC.

Chinese scientists have proposed a new theory that explains why humans are so much more intelligent than animals even though our brains are often much smaller than those of other species. Researchers at the Wuhan Institute of Neuroscience and Neuro-engineering have previously carried out studies backing the theory that the brain not only processes and passes on information not only through electrical and chemical signals, but also with photons of light.

Sure some things may be hyped up; however, not everything including hacking. And, I would not wish to see others make the mistake of believing that they will not be hacked by state funded hackers with access to a quantum network. Especially, when you understand China’s advances in QC and close partnerships with Australia’s QC labs and researchers.

A word of caution so we can all be excited for the right reasons.

In this video, D-Wave Systems Founder Eric Ladizinsky presents: The Coming Quantum Computing Revolution.

“Despite the incredible power of today’s supercomputers, there are many complex computing problems that can’t be addressed by conventional systems. Our need to better understand everything, from the universe to our own DNA, leads us to seek new approaches to answer the most difficult questions. While we are only at the beginning of this journey, quantum computing has the potential to help solve some of the most complex technical, commercial, scientific, and national defense problems that organizations face. We expect that quantum computing will lead to breakthroughs in science, engineering, modeling and simulation, financial analysis, optimization, logistics, and national defense applications.”

Eric Ladizinsky is a senior scientific management executive with a strong background in physics, engineering, materials, manufacturing and team building. Mr. Ladizinsky leads D-Wave’s technical effort to develop the superconducting integrated circuit fabrication process and is often called upon to evangelize on all aspects of quantum computing. At Northrop Grumman Space Technology (formerly TRW, Inc.), he ran a multi-million dollar DARPA program in Quantum Computing using superconducting integrated circuit technology. Mr. Ladizinsky has a BSc. Physics and Mathematics degree from the University of California, Los Angeles and is an Adjunct Professor of Physics at Loyola Marymount University.

As I highlighted earlier, we now understand more about the telescope announcement 3 months ago and its tie with the Quantum Satellite. Also, we are aware of China’s efforts to be the world leader of tech as they have proven in Pharmaceuticals (namely the generic brand market). Space is another area they have passion due to the opportunities in mining rare and raw materials, etc. Things are getting extremely interesting for sure.

BTW — the balance of tech power is changing; and we could see soon a day that folks look towards China stating the future of tech v. SV.

In 2016, with headlines announcing yesterday’s launch of the first quantum computer to the completion of the world’s largest radio telescope, China is emerging as the new science super power, opening portals to new and uncharted territory with some of the world’s most powerful and costly research hardware at their disposal.

Nice work; understanding the quantum effects in nanomechanical systems is closer to reality in being achieved. Imagine a nanobot or microbot with quantum mechanic properties.

Rob Knobel is probing the ultimate limits of nanomechanical systems to develop and build tiny vapour sensors, which could be used as airport security tools to prevent terrorism or drug smuggling.

He and his students are using highly specialized equipment in the $5-million Kingston Nano Fabrication Laboratory (KNFL), which opened a year ago in Innovation Park, to fabricate nanosensors made from graphene, a form of carbon a single atom thick.

“Graphene is the strongest, lightest material yet discovered, and it has remarkable electrical and mechanical properties. We’re developing graphene chemical sensors that can detect vapours in parts per billion or trillion concentration. These could potentially be used for detecting explosives or biological agents,” says Dr. Knobel, an associate professor, the Chair of Engineering Physics and a Queen’s Engineering graduate himself.
