Nanotechnology has reshaped the technological discoveries in the recent times. Nanotechnology has enabled the creation and invention of numerous things with wide potentialities. Every field is subject to constant evolution, nanotechnology is no exception. Researchers and scientists who are engaged with nanotechnology have now come up with femtotechnology.

Femtotechnology is widely defined as, “Hypothetical term used in reference to structuring of matter on the scale of a femtometer, which is 10^−15m. This is a smaller scale in comparison to nanotechnology and picotechnology which refer to 10^−9m and 10^−12m respectively.”

Hugo de Garis, an Australian AI researcher, wrote a few years ago in Humanity Plus Magazine on the power of the femtotechnology: “If ever a femtotech comes into being, it will be a trillion trillion times more “performant” than nanotech, for the following obvious reason. In terms of component density, a femtoteched block of nucleons or quarks would be a million cubed times denser than a nanotech block. Since the femtoteched components are a million times closer to each other than the nanotech components, signals between them, traveling at the speed of light, would arrive a million times faster. The total performance per second of a unit volume of femtoteched matter would thus be a million times a million times a million = a trillion trillion= 1024.”

Theory of a mach effect thruster I

The Mach Effect Thruster (MET) is a propellant—less space drive which uses Mach’s principle to produce thrust in an accelerating material which is undergoing mass—energy fluctuations. Mach’s principle is a statement that the inertia of a body is the result of the gravitational interaction of the body with the rest of the mass-energy in the universe. The MET device uses electric power of 100 — 200 Watts to operate. The thrust produced by these devices, at the present time, are small on the order of a few micro-Newtons. Researchers give a physical description of the MET device and apparatus for measuring thrusts. Next they explain the basic theory behind the device which involves gravitation and advanced waves to incorporate instantaneous action at a distance. The advanced wave concept is a means to conserve momentum of the system with the universe. There is no momentun violation in this theory. We briefly review absorber theory by summarizing Dirac, Wheeler-Feynman and Hoyle-Narlikar (HN). They show how Woodward’s mass fluctuation formula can be derived from first principles using the HN-theory which is a fully Machian version of Einstein’s relativity. HN-theory reduces to Einstein’s field equations in the limit of smooth fluid distribution of matter and a simple coordinate transformation.

It is shown that if Mach’s Principle is taken seriously, and the inertia of a body can be described as the interaction of the body with the rest of the universe, then the advanced and retarded fields transmitted between the particle and the universe can be used to explain the thrust observed in the Mach Effect drive experiments. This idea was originally put forward by one of the authors, James Woodward. The idea of inertia being a gravitational effect was first postulated by Einstein. In fact Mach’s principle was the foundation on which Einstein’s general relativity was based.

Again organic nature teaches technology.

A new study, inspired by water’s movement from roots to leaves in tall trees, shows that a certain kind of passive liquid flow, where liquids naturally move in response to surface atomic interactions instead of being driven by external forces like pumps, is remarkably strong. By virtually modeling the way atoms interact at a solid surface, College of Engineering and Computer Science researchers suggest that passive liquid flow could serve as a highly efficient coolant-delivery mechanism without the need for pumps. The results, published in Langmuir, also have implications for the development of new nanoscale technology.

Scientists may have found signs that phonons, the very small packets of energy that make up sound waves, were leaking out of sonic black holes, just as Hawking’s equations predicted.

Some 42 years ago, renowned theoretical physicist Stephen Hawking proposed that not everything that comes in contact with a black hole succumbs to its unfathomable nothingness. Tiny particles of light (photons) are sometimes ejected back out, robbing the black hole of an infinitesimal amount of energy, and this gradual loss of mass over time means every black hole eventually evaporates out of existence.

Known as Hawking radiation, these escaping particles help us make sense of one of the greatest enigmas in the known Universe, but after more than four decades, no one’s been able to actually prove they exist, and Hawking’s proposal remained firmly in hypothesis territory.

The team’s article in Nature Photonics says the demonstration ‘constitutes a milestone towards a global quantum internet,’ as it is one of the longest distances over which quantum teleportation has been achieved using a fibre-optic network in this way.

In a “major step” toward practical quantum networking, researchers at the University of Calgary have successfully demonstrated the teleportation of a light particle’s properties between their lab and the city’s downtown area, six kilometres away.

“What is remarkable about this is that this information transfer happens in what we call a disembodied manner,” said physics professor Wolfgang Tittel, whose team’s work was published this week in the journal Nature Photonics.

“Our transfer happens without any need for an object to move between these two particles.”

Is everyone ready for a new teleporting net?

Physicists have set a new bar for quantum teleportation: moving information from one place to another without physically sending anything between the locations.

Two separate teams managed to teleport information across several kilometres of optical fibre network in two cities.

This form of teleportation differs from that depicted in Star Trek: it involves transferring quantum states of a light particle, not Starfleet officers.

Quantum teleportation just moved out of the lab and into the real world, with two independent teams of scientists successfully sending quantum information across several kilometres of optical fibre networks in Calgary, Canada, and Hefei, China.

The experiments show that not only is quantum teleportation very much real, it’s also feasible technology that could one day help us build unhackable quantum communication systems that stretch across cities and maybe even continents.

Quantum teleportation relies on a strange phenomenon called quantum entanglement. Basically, quantum entanglement means that two particles are inextricably linked, so that measuring the state of one immediately affects the state of the other, no matter how far apart the two are — which led Einstein to call entanglement “spooky action at a distance”.

Researchers have observed quantum effects in electrons by squeezing them into one-dimensional ‘quantum wires’ and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.

Scientists have controlled electrons by packing them so tightly that they start to display quantum effects, using an extension of the technology currently used to make computer processors. The technique, reported in the journal Nature Communications, has uncovered properties of quantum matter that could pave a way to new quantum technologies.

The ability to control electrons in this way may lay the groundwork for many technological advances, including quantum computers that can solve problems fundamentally intractable by modern electronics. Before such technologies become practical however, researchers need to better understand quantum, or wave-like, particles, and more importantly, the interactions between them.

I remember when this was announced last year; however, I am glad to see the topic highlighted again especially after China’s launch of their Quantum Satellite.

Quantum teleportation is the mystical, far-off in the future idea where quantum information encoded into particles of light can be transferred from one place to another remotely. Except it’s not far-off in the future — it just happened. Teleportation is real and it is here.

The teleportation occurred over several kilometres of optical fibre networks in the cities of Hefei in China and Calgary in Canada.

The two independent studies show that quantum teleportation across metropolitan networks is technologically feasible, and pave the way towards future city-scale quantum technologies and communications networks, such as a quantum internet.

Scientists have shown they can teleport matter across a city, a development that has been hailed as “a technological breakthrough”.

However, do not expect to see something akin to the Star Trek crew beaming from the planet’s surface to the Starship Enterprise.

Instead, in the two studies, published today in Nature Photonics, separate research groups have used quantum teleportation to send photons to new locations using fibre-optic communications networks in the cities of Hefei in China and Calgary in Canada.
