Hmmm; like the graphic reminds of one of my posts.
In Brief.
Nice article; however, not sure if the author is aware Los Alamos already has a quantum net as well as some Europe banks have the capabilities and 4 months ago it was announced that a joint effort by various countries from Europe, Asia, etc. have come together to re-engineer the Net infrastructure with QC technology…
Maybe the quantum will giveth what the quantum taketh away… at least when it comes to secure transmissions.
There’s been much speculation that emerging quantum computers will become capable of breaking advanced public key cryptography systems, such as 2048-bit RSA. This might leave encrypted data transmissions exposed to anyone who happens to own such a quantum computer.
According to a recent report by the Global Risk Institute (GRI):
Whether for use in safe data encryption, ultrafast calculation of huge data volumes or so-called quantum simulation of highly complex systems: Optical quantum computers are a source of hope for tomorrow’s computer technology. For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip, as outlined Nature Photonics. This fulfills one condition for the use of photonic circuits in optical quantum computers.
“Experiments investigating the applicability of optical quantum technology so far have often claimed whole laboratory spaces,” explains Professor Ralph Krupke of the KIT. “However, if this technology is to be employed meaningfully, it must be accommodated on a minimum of space.” Participants in the study were scientists from Germany, Poland, and Russia under the leadership of Professors Wolfram Pernice of the Westphalian Wilhelm University of Münster (WWU) and Ralph Krupke, Manfred Kappes, and Carsten Rockstuhl of the Karlsruhe Institute of Technology (KIT).
The light source for the quantum photonic circuit used by the scientists for the first time were special nanotubes made of carbon. They have a diameter 100,000 times smaller than a human hair, and they emit single light particles when excited by laser light. Light particles (photons) are also referred to as light quanta. Hence the term “quantum photonics.”
This doesn’t surprise me at all given how we can leverage synthetic diamonds and their crystal formations for light networks, QC, and now storage.
Nuclear spins in diamond can store photonic information with high fidelity and have coherence times that exceed 10s, making diamond potentially useful as a node in quantum communications.
Quantum communications offer secure and fast information exchange between distant parties. To realize these links requires the building of quantum networks that incorporate stationary quantum nodes separated by large distances and photons (information carriers), which establish entanglement between the nodes1 (see Figure 1). Because such networks suffer unavoidable photon losses, enabling robust quantum communication over lossy transmission channels requires quantum memories with long coherence times to reliably store the incident photon states at any given node on the network.2 Hence, a quantum node should have the ability to coherently absorb/emit and store the information encoded in the photon state onto a memory element that has very long coherence times.
The University of Rochester has begun work on what they call a Quantum Enigma Machine. This new machine is said to be responsible for unbreakable encryption. It will also shorten encryption keys, and make data interception much more difficult than it already is.
American Mathematician Claude Shannon came up with a binary system that would allow him to transmit messages under three stipulations: the key is random, only used once, and it has to be as long as the message itself is.
Recent studies show that scientists are theorizing that they could send a message with unbreakable encryption with a key that is much shorter than the message itself. Their theory may soon become fact as researchers have developed the quantum enigma machine.
Researchers at the Karlsruhe Institute of Technology say they have developed a quantum photonic circuit with an electrically driven light source. Described as a ‘complete quantum optical structure on a chip’, the development is said to fulfil one condition for the use of photonic circuits in optical quantum computers.
“Experiments investigating the applicability of optical quantum technology have often claimed whole laboratory spaces,” said Professor Ralph Krupke. “However, if this technology is to be employed meaningfully, it must be accommodated on a minimum of space.”
The light source for the quantum photonic circuit is carbon nanotubes which emit single particles of light when excited by a laser. Because they emit single photons, carbon nanotubes are attractive as light sources for optical quantum computers.

Abstract The basic laws of deterministic many-body systems are summarized in the footsteps of the deterministic approach pioneered by Yakov Sinai. Two fundamental cases, repulsive and attractive, are distinguished. To facilitate comparison, long-range potentials are assumed both in the repulsive case and in the new attractive case. In Part I, thermodynamics – including the thermodynamics of irreversible processes along with chemical and biological evolution – is presented without paying special attention to the ad hoc constraint of long-range repulsion.
In Part II, the recently established new fundamental discipline of cryodynamics, based on long-range attraction, is described in a parallel format. In Part III finally, the combination (“dilute hot-plasma dynamics”) is described as a composite third sister discipline with its still largely unknown properties. The latter include the prediction of a paradoxical “double-temperature equilibrium” or at least quasi-equilibrium existing which has a promising technological application in the proposed interactive local control of hot-plasma fusion reactors. The discussion section puts everything into a larger perspective which even touches on cosmology.

Now, intriguing calculations from a research team at the Institute of Applied Physics of the Russian Academy of Sciences (IAP RAS), and reported this week in Physics of Plasmas, from AIP Publishing, explain the production and dynamics of electrons and positrons from ultrahigh-intensity laser-matter interactions. In other words: They’ve calculated how to create matter and antimatter via lasers.
Strong electric fields cause electrons to undergo huge radiation losses because a significant amount of their energy is converted into gamma rays — high-energy photons, which are the particles that make up light. The high-energy photons produced by this process interact with the strong laser field and create electron-positron pairs. As a result, a new state of matter emerges: strongly interacting particles, optical fields, and gamma radiation, whose dynamics are governed by the interplay between classical physics phenomena and quantum processes.
A key concept behind the team’s work is based on the quantum electrodynamics (QED) prediction that “a strong electric field can, generally speaking, ‘boil the vacuum,’ which is full of ‘virtual particles,’ such as electron-positron pairs,” explained Igor Kostyukov of IAP RAS. “The field can convert these types of particles from a virtual state, in which the particles aren’t directly observable, to a real one.”
When the quantum computer was imagined 30 years ago, it was revered for its potential to quickly and accurately complete practical tasks often considered impossible for mere humans and for conventional computers. But, there was one big catch: Tiny-scale quantum effects fall apart too easily to be practical for reliably powering computers.
Now, a team of scientists in Japan may have overcome this obstacle. Using laser light, they have developed a precise, continuous control technology giving 60 times more success than previous efforts in sustaining the lifetime of “qubits,” the unit that quantum computers encode. In particular, the researchers have shown that they can continue to create a quantum behavior known as the entangled state—entangling more than one million different physical systems, a world record that was only limited in their investigation by data storage space.
This feat is important because entangled quantum particles, such as atoms, electrons and photons, are a resource of quantum information processing created by the behaviors that emerge at the tiny quantum scale. Harnessing them ushers in a new era of information technology. From such behaviors as superposition and entanglement, quantum particles can perform enormous calculations simultaneously. The report of their investigation appears this week in the journal APL Photonics.
