Consciousness Lives in Quantum State After Death Physicists Claim

Posted by in categories: computing, neuroscience, particle physics, quantum physics


Testimonials from prominent physics researchers from institutions such as Cambridge University, Princeton University, and the Max Planck Institute for Physics in Munich claim that quantum mechanics predicts some version of “life after death.”

They assert that a person may possess a body-soul duality that is an extension of the wave-particle duality of subatomic particles.

Is Quantum the Future of High-Performance Analytics?

Posted by in categories: computing, particle physics, quantum physics

If you think quantum computing sounds like something out of science fiction, you’re not alone. It’s still more theory than practice, but it might be able to answer questions that are unsolvable by current computers. Earlier this year, IBM made a small quantum computer available via the cloud.

Quantum Mechanics and the Weirdness of Particles

To understand quantum computers, you must first know a little bit about quantum mechanics. In the briefest possible description, quantum mechanics is the branch of physics that models how particles behave at the smallest scales.

China successfully develops semiconductor quantum chip

Posted by in categories: computing, quantum physics

China has made a breakthrough in the research of quantum computing. The quantum laboratory of the University of Science and Technology of China recently announced its success in developing a semiconductor quantum chip.

According to a CNTV report on Aug. 11, the quantum chip is equivalent to the “brain” of future quantum computers; it enables quantum operations and information processing. Besides computing, technologies for quantum storage and control are also essential to the future of this technology. The “sandwich-type” solid-state quantum memory can be operational at a low temperature with magnetic auxiliary equipment.

Zhou Zongquan, a researcher at the Key Laboratory of Quantum Information under the Chinese Academy of Sciences (CAS), said that the direction of future development is to prolong the life of quantum memory.

Turning Quantum Theories Into Quantum Technologies

Posted by in categories: computing, nanotechnology, quantum physics

ACQUIRE researchers will confront major challenges in a four-year quest to engineer a quantum communication system on a chip. The chip will need to operate at room temperature with low energy in a fiber optic network with entangled photons.

Currently, such a communication system may be demonstrated in laboratories, but only at cryogenic (very low) temperatures, and with bulky, energy-intensive equipment. However, a fundamental understanding of quantum physics and optical materials, as well as recent progress in nanoscale photonic integration, have brought communication systems scaled to the quantum level within reach.

If successful, the ACQUIRE teams’ results will begin to realize the hardware needed for secure and efficient quantum communication. The findings from the ACQUIRE projects will also advance quantum sensing and computing.

Quantum dots with impermeable shell used as a powerful tool for “nano-engineering”

Posted by in categories: 3D printing, chemistry, engineering, nanotechnology, quantum physics, wearables

I never get tired of talking about the many uses for Q-dot technology. One area that has me even more intrigued is how it is used in crystallized formations. I expect to see more and more experimenting on crystalized formations on many fronts including complex circuitry for performance and storage.

And, with synthetic technology today plus 3D printing along with Q-dots we could (as I have eluded to many times over several months) truly begin to see some amazing technology be developed on the wearable tech front.

Wearables could include synthetic circuitry stones in various accessories to not only store information, but also serve as another form of unique id because in synthetic stones we have been able (like in nature) create complex crystalized formations that are each unique/ 1 of a kind like a unique finger print, or iris of an eye. I expect to see some very interesting things coming in this space.

Toward practical quantum computers

Posted by in categories: computing, quantum physics

Built-in optics could enable chips that use trapped ions as quantum bits…

Researchers from MIT and MIT Lincoln Laboratory report an important step toward practical quantum computers, with a paper describing a prototype chip that can trap ions in an electric field and, with built-in optics, direct laser light toward each of them.

Quantum computing and cryptocurrencies: Are Steemit and bitcoin safe?

Posted by in categories: bitcoin, computing, cryptocurrencies, encryption, quantum physics, security

Article repeats a lot of the knowns on QC such as bit v. Qubit; and finally provides some good info on pros and cons of Bitcoin and Lamport signatures technique with QC. However, the author didn’t seem to mention any of the work that D-Wave for example is doing with Block chaining. Also, I saw no mention of the work by Oxford on the logic gate which improve both the information processing performance and the security of information transmissions.

In a classical computer bits are used that can either be 0 or 1. In a quantum computer these bits are replaced with Qubits (quantum bits). These Qubits can be 0 or 1, or both at the same time. This is caused by a phenomenon in the quantum realm called superposition. At scales the size of an atom and small molecules, the spin of particles is not determined until it is observed. A pair of Qubits can be in any quantum superposition of 4 states, and three Qubits in any superposition of 8 states. In general, a quantum computer with n Qubits can be in a superposition of up to 2^n different states simultaneously (this compares to a normal computer that can only be in one of these 2^n states at any one time). Because of this, a quantum computer is able to perform computations at the same time, while classical computers perform computations one at a time.

What makes the spin flip over?

Posted by in categories: nanotechnology, quantum physics

The Einstein-de-Haas effect shows that magnetism results from the angular momentum of electrons and is considered as the macroscopic evidence of electron spin. Researchers at Karlsruhe Institute of Technology (KIT) and at the Institut NÉEL at the CNRS in Grenoble were the first to investigate this effect for an individual spin and formulated it as the new “Quantum Einstein-de-Haas effect”. In Nature Communications, they report on their work (“Quantum Einstein-de Haas effect”).
