Interesting read on IPC Systems Inc. is partnering with U.K. startup Post-Quantum to (in their own words) “offer its clients encryption, biometric authentication and a distributed-ledger record-keeping system that the software company says is designed to resist hacking — even by a quantum computer.” — I will be researching this more.

(Bloomberg) — When it comes to cybersecurity, no one can accuse IPC Systems Inc., the New Jersey-based company that builds communications networks for trading firms and financial markets, of preparing to fight the last war.

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.

Hold on tight folks, this hits the “deep woo” early!

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.

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.

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.

(Note that this is completely different from quantum cryptography, which is a way of passing bits between two parties that relies on physical quantum properties for security. The only thing quantum computation and quantum cryptography have to do with each other is their first words. It is also completely different from the NSA’s QUANTUM program, which is its code name for a packet-injection system that works directly in the Internet backbone.)
