China’s newest tech can offer quantum of security

Posted by in categories: cybercrime/malcode, economics, encryption, finance, quantum physics, security

Very concerning news for the US security; we’ll see how the US responds. Remember, our largest hackers in the US is China; so we’ll need to determine what this means as well as how vulnerable we are.

Crunching Quantum Code

Posted by in categories: computing, quantum physics

MIT has developed a quantum computer design featuring an array of superconducting islands on the surface of a topological insulator that they’re experimenting with to process 0’s & 1’s — if they are successful; this could possibly get us within a 5 yr window for QC platforms.


Massachusetts Institute of Technology (MIT) researchers have developed a quantum computer design featuring an array of superconducting islands on the surface of a topological insulator.

The researchers propose basing both quantum computation and error correction on the peculiar behavior of electrons at neighboring corners of these islands and their ability to interact across islands at a distance.

Tactics to Protect Against Most Common Cyber Attacks

Posted by in categories: business, cybercrime/malcode, energy, mobile phones, quantum physics, robotics/AI

This is a good baseline around common known issues — the real problem is cyber terrorists (as I call them) learns from each attack they instigate and like an artist, they constantly are fine tuning their own skill. So, the attacker’s approach and execution may be done one way, and by the next attack they can easily have changed their whole attack model completely which makes it very cumbersome for experts to trace at times. If we believe this is bad now; wait until AI is more widely available and adopted. Or, Quantum ends up in the hands of these guys.


Cybercrimes in today’s technologically advanced society have become much more sophisticated and progressive. We can thank mobility for the ease of extended access to our personal data, as with every use of our mobile phones, laptops or tablets in public areas we further increase our risk and vulnerability. As business owners, online shoppers, students, employees and even house wives, we remain at high risk for intrusion of our virtual systems. In this digital day in age, our personal data is used everywhere from when we make an online banking transaction to buying a new shirt at the mall, and even working on a project at the local coffee shop. It is hardly responsible to think that your information is safe anywhere.

Researchers demonstrate ‘quantum surrealism’

Posted by in categories: particle physics, quantum physics

Proving Quantum


New research demonstrates that particles at the quantum level can in fact be seen as behaving something like billiard balls rolling along a table, and not merely as the probabilistic smears that the standard interpretation of quantum mechanics suggests. But there’s a catch — the tracks the particles follow do not always behave as one would expect from “realistic” trajectories, but often in a fashion that has been termed “surrealistic.”

In a new version of an old experiment, CIFAR Senior Fellow Aephraim Steinberg (University of Toronto) and colleagues tracked the of photons as the particles traced a path through one of two slits and onto a screen. But the researchers went further, and observed the “nonlocal” influence of another photon that the first photon had been entangled with.

Moving electrons around loops with light: A quantum device based on geometry

Posted by in categories: electronics, engineering, quantum physics

More news on Qubits that are surprisingly intrinsically resilient to noise.


While a classical bit found in conventional electronics exists only in binary 1 or 0 states, the more resourceful quantum bit, or ‘qubit’ is represented by a vector, pointing to a simultaneous combination of the 1 and 0 states. To fully implement a qubit, it is necessary to control the direction of this qubit’s vector, which is generally done using fine-tuned and noise-isolated procedures.

Researchers at the University of Chicago’s Institute for Molecular Engineering and the University of Konstanz have demonstrated the ability to generate a quantum logic operation, or rotation of the qubit, that — surprisingly — is intrinsically resilient to noise as well as to variations in the strength or duration of the control. Their achievement is based on a geometric concept known as the Berry phase and is implemented through entirely optical means within a single electronic spin in diamond.

Physicists discover easy way to measure entanglement—on a sphere

Posted by in categories: mathematics, quantum physics

Measuring entanglement — the amount of entanglement between states corresponds to the distance between two points on a Bloch sphere.

To do this, the scientists turned the difficult analytical problem into an easy geometrical one. They showed that, in many cases, the amount of entanglement between states corresponds to the distance between two points on a Bloch sphere, which is basically a normal 3D sphere that physicists use to model quantum states.

As the scientists explain, the traditionally difficult part of the math problem is that it requires finding the optimal decomposition of mixed states into pure states. The geometrical approach completely eliminates this requirement by reducing the many possible ways that states could decompose down to a single point on the sphere at which there is zero entanglement. The approach requires that there be only one such point, or “root,” of zero entanglement, prompting the physicists to describe the method as “one root to rule them all.”

Obama wants to spend $19 billion on cyber security

Posted by in categories: business, cybercrime/malcode, employment, health, quantum physics

One thing that will remain with tech for many years is jobs in cyber security — even with the layer of security that Quantum technology brings in the next 10 years; there is always a migration and retirement state that can (depending on the business and systems involved) could go on for years after Quantum platforms and networks are installed.


Then in December, aided and abetted by a Republican-controlled Congress, he eradicated those minor restrictions and replaced mindless austerity with clueless profligacy.

It proposes lifting the limits entirely from 2018. “It adheres to last year’s bipartisan budget agreement, it drives down the deficit, and includes smart savigs on health care, immigration and tax reform”.

Oxford Instruments and SPECS Surface Nano Analysis GmbH sign agreement for Nanonis Tramea quantum transport measurement system

Posted by in categories: computing, electronics, materials, quantum physics

This agreement places Oxford in a very nice position.


Quantum transport measurements are widely used in characterising new materials and devices for emerging quantum technology applications such as quantum information processing (QIP), quantum computing (QC) and quantum sensors. Such devices hold the potential to revolutionise future technology in high performance computing and sensing in the same way that semiconductors and the transistor did over half a century ago.

Physicists have long used standard electrical transport measurements such as resistivity, conductance and the Hall effect to gain information on the electronic properties and structure of materials. Now quantum transport measurements such as the quantum Hall effect (QHE) and fractional quantum Hall effect (FQHE) in two-dimensional electron gases (2DEG) and topological insulators – along with a range of other more complex measurements – inform researchers on material properties with quantum mechanical effects.
