CERN & D-Wave’s Quantum Key To The Abyss & Beyond

Posted by in categories: computing, quantum physics

Interesting recorded show on how each person has been assigned a unique node which can replicate the person digitally in a virtual world. And, how DoD and D-Wave is involved. Not sure how factual this is; but an interesting concept.

Anthony Patch, author researcher & public speacker, is back on The Kev Baker Show. This time out we discuss how CERN & quantum computers literally hold the key to unlocking a multidimensional reality.

New Condensed Matter State Paves the Way for Scalable Quantum Computers

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

Rice physicists are closing in on a method that will create a new condensed matter state in which all electrons in a material act as one by manipulating them with light and a magnetic field. This research advance technologies such as quantum computers.

For particle physicists, studying the interactions between photons and electrons has long been an area of interest. After all, observing such phenomena could eventually lead us to the creation of a viable quantum computer.

Physicist Junichiro Kono and his colleagues at Rice University are making headway on a method to create a new condensed matter state, where electrons in a material “couple” after they are manipulated with light and a magnetic field.

Building devices from colloidal quantum dots

Posted by in categories: materials, quantum physics

Meet the punk rock version of Device making via Q-Dots.

A wide range of materials can now be synthesized into semiconducting quantum dots. Because these materials grow from solutions, there is scope to combine quantum dots into devices by using simple, low-cost manufacturing processes. Kagan et al. review recent progress in tailoring and combining quantum dots to build electronic and optoelectronic devices. Because it is possible to tune the size, shape, and connectivity of each of the quantum dots, there is potential for fabricating electronic materials with properties that are not available in traditional bulk semiconductors.

The NSA Plans for a Post-Quantum World

Posted by in categories: computing, encryption, government, information science, internet, privacy, quantum physics, security

Hope they’re working with QC researchers in Los Alamos and DARPA; it is the US Government which is known for its silos and multi-layer bureaucracies.

Quantum computing is a novel way to build computers — one that takes advantage of the quantum properties of particles to perform operations on data in a very different way than traditional computers. In some cases, the algorithm speedups are extraordinary.

Specifically, a quantum computer using something called Shor’s algorithm can efficiently factor numbers, breaking RSA. A variant can break Diffie-Hellman and other discrete log-based cryptosystems, including those that use elliptic curves. This could potentially render all modern public-key algorithms insecure. Before you panic, note that the largest number to date that has been factored by a quantum computer is 143. So while a practical quantum computer is still science fiction, it’s not stupid science fiction.

The magic of the game changing electric dark matter black holes BH in the crowded centers of galaxies

Posted by in categories: cosmology, quantum physics

New electric dark matter black holes seem to be game changers if concentrated in galaxy centers.

Game changing because BH crowded areas do not form linear Herbig Haro systems with star formation in between.

Result: Red and Dead galaxies as the start of the decline and big crunch.

Quantum Entanglement: Slower Than Light

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

Although this is true (speed of communication via entanglement is not at the speed of light); like other early stage technologies this will also evolve and improve in time.

China recently launched a satellite to test quantum entanglement in space. It’s an interesting experiment that could lead to “hack proof” satellite communication. It’s also led to a flurry of articles claiming that quantum entanglement allows particles to communicate faster than light. Several science bloggers have noted why this is wrong, but it’s worth emphasizing again. Quantum entanglement does not allow faster than light communication.

This particular misconception is grounded in the way quantum theory is typically popularized. Quantum objects can be both particles and waves, They have a wavefunction that describes the probability of certain outcomes, and when you measure the object it “collapses” into a particular particle state. Unfortunately this Copenhagen interpretation of quantum theory glosses over much of the subtlety of quantum behavior, so when it’s applied to entanglement it seems a bit contradictory.
