Building Bridges between Synchronization and Quantum Entanglement in Networks



The similarities between so-called classical synchronization and quantum entanglement is not lost on some of the emergent, self-similar behavior, that exists in these systems. This can be seen in the systems themselves, separately. Perturbations in quantum systems lead to discontinuities that can lead to decoherence however systems of entangled quantum oscillators can also display error-correction in certain topological states, such as toric and/or surface codes. Classical systems meanwhile display so-called chimera states that exist as a "phase state" between order and disorder to an extent that these states can actually steer a self-organised system back from a chaotic edge and maintain itself durable. I have explored these concepts in a previous video: However here I wish to showcase some of the actual simulations I've done with software and hardware which does not necessarily take us into using the exotic systems found in a quantum optics lab. Metaheuristic algorithms meanwhile that port and parse some of the measurement spaces found in quantum systems, i.e. the Poincare/Bloch/Riemann Sphere and represent them as "squashed" pseudo-quantum states represented as HSV values say can nevertheless display some of the "quantumness" which can be described using, among other things, the path integral formalism of quantum mechanics and even resembles the behavior of real-world quantum states of matter such as entangled networks, Bose-Einstein condensates, currents and flows of Cooper pairs in superconductors etc. From all of this we could very well as, are all of these variations on a common physical theme? Another question we could ask in this research is, at what scale does entanglement end and synchronization begin and vice versa?

Experiment in making Periodically-Poled KTP (ppKTP) for Quantum Optics Research using off-the-shelf KTP



a big focus of my research is buying bespoke optics components and repurposing them for quantum optics experiments and the relative abundance of KTP (potassium titanyl phosphate) along with micro electrodes motivated me (among others things) to try and see if current setups using BBO (beta-barium borate) can be enhanced with modified components that would otherwise be prohibitively expensive to integrate into existing systems. Measuring the degree of polarization-entanglement is the next step and it too uses a lot of off-the-shelf technology but, again, restructured for a different purpose. In many instances the research goal is to create new architectures in networks that already exist in the classical domain. As a point of fact a lot of my research has taken me into bridging classical networks and their components into the emerging field of "quantum" networks. In many ways the components for "quantum" networks already exist, the networks themselves just have to be tailored with a different approach than before.
