A gravitational wave generating device comprising an energizing means such as magnetrons, which act upon energizable elements such as film bulk acoustic resonators or FBARs. A computer that controls the magnetrons’ phase. A gravitational wave generation device that exhibits directivity and forms a gravitational-wave beam. The utilization of a medium in which the gravitational wave speed is reduced in order to effect refraction of the gravitational wave and be a gravitational wave lens. A gravitational wave generator device that can be directed in order to propel an object by its momentum or by changing the gravitational field nearby the object to urge it in a preferred direction and be a propulsion means.

Quantum chemistry on quantum computers
Posted by Quinn Sena in categories: chemistry, computing, particle physics, quantum physics
The special properties of quantum computers should make them ideal for accurately modelling chemical systems, Philip Ball discovers.
‘If you want to make a simulation of nature,’ the legendary physicist Richard Feynman advised in 1981, ‘you’d better make it quantum-mechanical.’ By ‘nature’, Feynman meant ‘stuff’: the particles and atoms and molecules we’re made from. His comment came in a talk published the following year, and is generally regarded as the founding text of quantum computing. It now looks even more prophetic than ever.
For although we are constantly told that the unique selling point of quantum computers is their enormous speed compared with the classical devices we currently use – a speed-up that exploits the counterintuitive laws of quantum mechanics – it seems that the most immediate benefit will be the one Feynman identified in the first place: we’ll be able to simulate nature better.
In keeping with the spirit of the age, researchers can think of the laws of physics as computer programs and the universe as a computer.

Spacetime Geometry near Rotating Black Holes Acts Like Quantum Computer, Physicist Says
Posted by Quinn Sena in categories: computing, cosmology, quantum physics
According to a theoretical paper published in the Annals of Physics, by Dr. Ovidiu Racorean from the General Direction of Information Technology in Bucharest, Romania, the geometry of spacetime around a rapidly spinning black hole (Kerr black hole) behaves like a quantum computer, and it can encode photons with quantum messages.

How Peter Shor’s Algorithm is Destined to Put an End to Modern Encryption
Posted by Quinn Sena in categories: computing, encryption, information science, internet, quantum physics
RSA Encryption is an essential safeguard for our online communications. It was also destined to fail even before the Internet made RSA necessary, thanks the work of Peter Shor, whose algorithm in 1994 proved quantum computers could actually be used to solve problems classical computers could not.

The Quatron Transistor
Posted by Richard Christophr Saragoza in categories: computing, engineering, particle physics, quantum physics
Atomic BECs were first achieved in 1995. Although it has become easier to realize atomic BECs since their discovery, they still require very low temperatures for operation. For most purposes, this is too expensive and impractical. Alternatively, negatively charged quatrons are quasi-particles composed of a hole and three electrons which form a stable BEC when coupled to light in triple quantum layer structures in semiconductor microcavities. This allows for both the greater experimental control found in quantum optics, and the benefits of matter wave systems, such as superconductivity and coherence. Moreover, due to the extremely small effective mass of the quasi-particles, quatrons can be used to achieve superconducting BECs at room temperature.
The Create the Future Design Contest was launched in 2002 by the publishers of NASA Tech Briefs magazine to help stimulate and reward engineering innovation. The annual event has attracted more than 8,000 product design ideas from engineers, entrepreneurs, and students worldwide.

Carbon nanotubes found in children’s lungs for the first time
Posted by Richard Christophr Saragoza in categories: computing, nanotechnology
By Sam Wong
Carbon nanotubes have turned up in the lungs of children living in Paris – the first time they have been detected in humans.
Incredibly strong, light and conductive, nanotubes have shown great potential in areas such as computing, clothing and healthcare technology. Nevertheless, there has been some concern over their use after mouse studies showed that injected nanotubes can cause immune reactions similar to those produced by asbestos.
