Posted by in categories: biotech/medical, computing, electronics, quantum physics

Researchers from the University of Bristol in the UK and Nippon Telegraph and Telephone (NTT) in Japan, have developing an optical chip that can process photons in an infinite number of ways.

It’s a major step forward in creating a quantum computer to solve problems such as designing new drugs, superfast database searches, and performing otherwise intractable mathematics that aren’t possible for super computers.

The fully reprogrammable chip brings together a multitude of existing quantum experiments and can realise a plethora of future protocols that have not even been conceived yet, marking a new era of research for quantum scientists and engineers at the cutting edge of quantum technologies.

IBM Watson CTO: Quantum computing could advance artificial intelligence

Posted by in categories: computing, engineering, futurism, quantum physics, robotics/AI

IBM Watson CTO: Quantum computing could advance artificial intelligence by orders of magnitude.

Quantum computers have already been used to test artificial intelligence by researchers in China, albeit in a very limited capacity. Earlier in 2015, a team from the country’s University of Science and Technology developed a quantum system capable of recognising handwritten characters in a demonstration they dubbed quantum artificial intelligence.

This demonstration was on a quantum computer using only four qubits, leading to speculation of what a system using hundreds – or even thousands – of qubits would be capable of. Such machines do not yet exist, at least not commercially, but Canada-based quantum computing firm D-Wave systems recently claimed it has built a 1,000 qubit quantum computer.

Strings Are Dead

Posted by in categories: anti-gravity, cosmology, defense, general relativity, gravity, innovation, particle physics, philosophy, physics, policy, quantum physics, science, space travel

In 2014, I submitted my paper “A Universal Approach to Forces” to the journal Foundations of Physics. The 1999 Noble Laureate, Prof. Gerardus ‘t Hooft, editor of this journal, had suggested that I submit this paper to the journal Physics Essays.

My previous 2009 submission “Gravitational acceleration without mass and noninertia fields” to Physics Essays, had taken 1.5 years to review and be accepted. Therefore, I decided against Prof. Gerardus ‘t Hooft’s recommendation as I estimated that the entire 6 papers (now published as Super Physics for Super Technologies) would take up to 10 years and/or $20,000 to publish in peer reviewed journals.

Prof. Gerardus ‘t Hooft had brought up something interesting in his 2008 paper “A locally finite model for gravity” that “… absence of matter now no longer guarantees local flatness…” meaning that accelerations can be present in spacetime without the presence of mass. Wow! Isn’t this a precursor to propulsion physics, or the ability to modify spacetime without the use of mass?

As far as I could determine, he didn’t pursue this from the perspective of propulsion physics. A year earlier in 2007, I had just discovered the massless formula for gravitational acceleration g=τc^2, published in the Physics Essays paper referred above. In effect, g=τc^2 was the mathematical solution to Prof. Gerardus ‘t Hooft’s “… absence of matter now no longer guarantees local flatness…”

Honda’s Gravity Modification Research

Posted by in categories: anti-gravity, business, cosmology, defense, disruptive technology, engineering, general relativity, gravity, innovation, particle physics, physics, quantum physics, science, space travel

Gravity modification, the scientific term for antigravity, is the ability to modify the gravitational field without the use of mass. Thus legacy physics, the RSQ (Relativity, String & Quantum) theories, cannot deliver either the physics or technology as these require mass as their field origin.

Ron Kita who recently received the first US patent (8901943) related to gravity modification, in recent history, introduced me to Dr. Takaaki Musha some years ago. Dr. Musha has a distinguished history researching Biefeld-Brown in Japan, going back to the late 1980s, and worked for the Ministry of Defense and Honda R&D.

Dr. Musha is currently editing New Frontiers in Space Propulsion (Nova Publishers) expected later this year. He is one of the founders of the International Society for Space Science whose aim is to develop new propulsion systems for interstellar travel.

Wait. What? Honda? Yes. For us Americans, it is unthinkable for General Motors to investigate gravity modification, and here was Honda in the 1990s, at that, researching this topic.

Is Photon Based Propulsion, the Future?

Posted by in categories: anti-gravity, defense, general relativity, gravity, innovation, particle physics, physics, quantum physics, science, space travel

I first met Dr. Young Bae, NIAC Fellow, at the Defense Advanced Research Projects Agency (DARPA) sponsored 2011, 100 Year Starship Study (100YSS) at Orlando, Fla. Many of us who were there had responded to the NASA/DARPA Tactical Technology Office’s RFP to set up an organization “… to develop a viable and sustainable non-governmental organization for persistent, long-term, private-sector investment into the myriad of disciplines needed to make long-distance space travel viable …”

Yes, both DARPA and NASA are at some level interested in interstellar propulsion. Mine was one of approximately 35 (rumored number) teams from around the world vying for this DARPA grant, and Dr. Bae was with a competing team. I presented the paper “Non-Gaussian Photon Probability Distributions”, and Dr. Bae presented “A Sustainable Developmental Pathway of Photon Propulsion towards Interstellar Flight”. These were early days, the ground zero of interstellar propulsion, if you would.

Dr. Bae has been researching Photon Laser Thrust (PLT) for many years. A video of his latest experiment is available at the NASA website or on YouTube. This PLT uses light photons to move an object by colliding with (i.e. transferring momentum to) the object. The expectation is that this technology will eventually be used to propel space crafts. His most recent experiments demonstrate the horizontal movement of a 1-pound weight. This is impressive. I expect to see much more progress in the coming years.

At one level, Dr. Bae’s experiments are confirmation that Bill Nye’s Light Sail (which very unfortunately lost communications with Earth) will work.

The Feasibility of Interstellar Propulsion

Posted by in categories: cosmology, defense, disruptive technology, general relativity, gravity, innovation, particle physics, philosophy, physics, policy, quantum physics, space travel

Recent revelations of NASA’s Eagleworks Em Drive caused a sensation on the internet as to why interstellar propulsion can or cannot be possible. The nay sayers pointed to shoddy engineering and impossible physics, and ayes pointed to the physics of the Alcubierre-type warp drives based on General Relativity.

So what is it? Are warp drives feasible? The answer is both yes and no. Allow me to explain.

The empirical evidence of the Michelson-Morley experiment of 1887, now known as the Lorentz-FitzGerald Transformations (LFT), proposed by FitzGerald in 1889, and Lorentz in 1892, show beyond a shadow of doubt that nothing can have a motion with a velocity greater than the velocity of light. In 1905 Einstein derived LFT from first principles as the basis for the Special Theory of Relativity (STR).

So if nothing can travel faster than light why does the Alcubierre-type warp drive matter? The late Prof. Morris Klein explained in his book, Mathematics: The Loss of Certainty, that mathematics has become so powerful that it can now be used to prove anything, and therefore, the loss of certainty in the value of these mathematical models. The antidote for this is to stay close to the empirical evidence.

Quantum Entanglement: EPR Paradox

Posted by in categories: encryption, general relativity, physics, quantum physics, science

When I was a freshman at Cornell University some decades ago, I had a memorable teaching assistant for CS100, the entry level computer programming course taken by nearly every student in Engineering or Arts & Sciences. Gilles Brassard, a French Canadian, is now a chaired math professor at Université de Montréal and a preeminent cryptographer. He has also been inducted into the Royal Order of Canada. I am told that this is a bit like being knighted. In fact, this highest of civilian honors was established by Queen Elizabeth.

Gilles was a graduate student at Cornell in the mid ’70s. Back then, public key encryption was a radical concept. Named for three MIT professors who described it, RSA is now it is at the heart of every secure Internet transaction. Yet, the new generation of cryptographers refers to RSA as “classical cryptography”. The radicals have moved on to Quantum Cryptography. Gilles and his collaborator, Charles Bennett, are the pioneers and leaders in this burgeoning field. No one else is even pretender to the throne.

In its simplest terms, quantum cryptography achieves a secure communication channel because it relies on a stream of individual particles or “quanta” to convey information. If information is sent without any fat at all—just the minimum physics that can support the entropy—then any eavesdropping or rerouting of a message can be detected by the recipient. Voila! Perfect authentication, fidelity and security. Communication is secure because any attack can be detected.
