Fear sells in the computer security business, and quantum computers could be very scary

Posted by in categories: cybercrime/malcode, particle physics, quantum physics

Interesting article; however, 2 things missing from it. 1) China has already implemented a QC wireless network and in phase 2 of their work on QC communications which is also involving a QC platform and hacking. 2) Author stated that Mosca believes by 2026 a nation state will have QC. I would suggest Mosca network a little more as China and Sydney are well ahead of schedule plus many of us involved in QC already are testing the scalability of QC on small devices and other platforms v. mammoth servers thanks to much of the new findings last year on proving the reliability and traceability of particles at various complex states of entanglement and information processing as well as the more recent findings of enabling the constant cold temperatures needed to support QC on small servers.

My own estimates is we’re within a 5 year window of being able to see a more pragmatic version of QC as servers and networking for the broader masses. I don’t believe we’re 10 years away or less than 5 years at the moment; however, things could change tomorrow to the point we see the timeline shortened from 5 to 3 years as I do have friends who believe we’re within 3 years.


Even though quantum computers don’t exist yet, security companies are preparing to protect against them.

Vanishing point: the rise of the invisible computer

Posted by in categories: computing, nanotechnology, quantum physics

Yep; devices and computers will no longer be needed given the advancements that are coming in areas of Quantum, Synbio, nanotech, etc.

However, with QC crystal technology and the work done on parallel states we have some very interesting things coming in communications, entertainment/ media, etc.


The long read: For decades, computers have got smaller and more powerful, enabling huge scientific progress. But this can’t go on for ever. What happens when they stop shrinking?

Scientists have confirmed a brand new form of matter: time crystals

Posted by in categories: computing, quantum physics, time travel

More information on the time crystals to simulate time travel.


Two more teams of researchers have found ways to create time crystals, lattices that repeat not in space but in time, breaking time-translation symmetry.

Though applications are unclear, the research could help us better understand quantum properties and solve the problem of quantum memory associated with quantum computing. Time crystals repeat their atomic structure in time. At the very least, they are a contradiction.

Physicists Simulate Sending Particles of Light Into the Past, Strengthening the Case that Time Travel Is Possible

Posted by in categories: cosmology, particle physics, quantum physics, time travel

Awesome! More news on the time crystals.


The source of time travel speculation lies in the fact that our best physical theories seem to contain no prohibitions on traveling backward through time. The feat should be possible based on Einstein’s theory of general relativity, which describes gravity as the warping of spacetime by energy and matter. An extremely powerful gravitational field, such as that produced by a spinning black hole, could in principle profoundly warp the fabric of existence so that spacetime bends back on itself. This would create a “closed timelike curve,” or CTC, a loop that could be traversed to travel back in time.

Quantum Breakthrough: Physicists Have Once More Created Time Crystals

Posted by in categories: computing, quantum physics

In Brief

  • Two more teams of researchers have found ways to create time crystals, lattices that repeat not in space but in time, breaking time-translation symmetry.
  • Though applications are unclear, the research could help us better understand quantum properties and solve the problem of quantum memory associated with quantum computing.

Time crystals are strange. At the very least, they are a contradiction. A time crystal is quantum phenomenon that demonstrates movement while remaining in its ground, or lowest energy, state. Essentially a non-equilibrium form of matter, time crystals are lattices that repeat not in space but in time, breaking time-translation symmetry.

When the idea of a time crystal was proposed in 2012 by physicist and Nobel laureate Frank Wilczek, it was only a theoretical possibility that would challenge many of the laws of physics. Then, in October 2016, a team of researchers from the University of California, Santa Barbara (UCSB) managed to make a “floquet time crystal.”

Simulating particle physics in a quantum computer

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

Particle physics is an interesting and complicated field of study. Its theoretical framework, the Standard Model, was developed during the second half of the twentieth century and it opened he possibility to explaining the behavior of the basic blocks of the Universe. It also classified all the particles, from the electron (discovered in 1897) to the Higgs Boson (found in 2012). It is not pretentious to claim that it is one of the most successful theories in Science.

Unfortunately, the Standard Model is also a very difficult theory to handle. By using an analytic approach many problems cannot be solved and computational methods require a huge computational power. Most of the simulations about this theory are performed in supercomputers and they have severe limitations. For instance, the mass of the proton can be calculated by the use of a technique called Lattice Quantum Chromodynamics (lattice QCD), but even using a supercomputer of the Blue Gene type the error was around 2% . This is a huge achievement that shows the utility of the theory, but it is also a signal about the necessity of developing new numerical tools to handle this kind of calculations.

One potential solution to this problem is to use quantum systems in order to perform the simulations. This idea is at the core of the field of quantum computing and it was first proposed by one of the pioneers in the study of particle physics, Richard Feynman . Feynman’s idea is easy to explain. Quantum systems are very difficult to simulate by the use of ordinary classical computers but by using quantum systems we can simulate different quantum systems. If we have a quantum system that we cannot control but we can mimic its dynamics to a friendly quantum system we have solved the problem. We can just manipulate the second system and infer the results to the first one.

Chiral Quantum Optics: A New Research Field with Bright Perspectives

Posted by in categories: education, quantum physics

Recently, surprising physical effects were observed using special microscopic waveguides for light. Such “photonic structures” currently are revolutionizing the fields of optics and photonics, and have opened up the new research area of “Chiral Quantum Optics”. Physicists from Copenhagen, Innsbruck, and Vienna, who are leading figures in this field, have now written an overview on the topic which just appeared in the scientific journal “Nature”.

What one learns at school is that light oscillates under a right angle (transversal) with respect to its direction of propagation. Among experts, however, it was already known that light behaves differently when it is confined strongly in the transversal plane using so-called “photonic structures”. In particular, this is the case for special ultra-thin glass fibers which have a diameter of only a few hundred nanometers (one nanometer is a millionth part of a millimeter) and which are thereby smaller than the wavelength of light. Also waveguides based on so-called “photonic crystals” (two-dimensional structures with periodically arranged holes) can confine light in this way.

In this situation, the light also oscillates along its propagation direction (longitudinal). The combination of transversal and longitudinal oscillation leads to a rotating electric field which physicist call circular polarization. Without the spatial confinement, the electric field associated with circularly polarized light behaves like the propeller of an aircraft whose axis is parallel to the direction of propagation. “However, in narrow photonic waveguides, the electric field of the light resembles the rotor of a helicopter,” explains Arno Rauschenbeutel from the Vienna Center for Quantum Science and Technology at the Institute of Atomic and Subatomic Physics of TU Wien, Austria. Here, the spin of the light points along the axis of the rotor and is therefore oriented perpendicular to the propagation direction of the light.
