In this video I show how I made a self-organisating network of Kuramoto-style oscillators in a system undergoing metaheuristic-guided synchronization. There are also ways to visually demonstrate this with relatively simple hardware, such as using modified microelectronics, controlled using microcontroller circuits.
In this project, which I have dubbed “Feynman’s Quantum Fireflies” I program individual systems of oscillators which display discontinuous pas coupling which can be implemented in a network of transceiver circuits. Using the Path Integral Approach is one way to understand how the system behaves like a quantum thermal bath.
This example is a self-organising network of flashing optical transceiver circuits, each circuit containing and RGB LED and phototransistor.
Each circuit is programmed under a simple principle of discontinuous pas-coupling as discussed before to achieve synchronization but this results in behavior across the entire network space that is a collective emergent behavior that has not been explicitly programmed, it emerges as a discrete simulation of a pseudo-quantum system.
This emergent behavior of the network is in fact a visual demonstration of how the network regulates itself over time to the most energy efficient configuration possible, which is to the state of most uniform synchronisation.
We can understand this synchronized state as being the ground state of our whole system, which the set of oscillators wants to head towards.
MIT researchers and colleagues have discovered an important—and unexpected—electronic property of graphene, a material discovered only about 17 years ago that continues to surprise scientists with its interesting physics. The work, which involves structures composed of atomically thin layers of materials that are also biocompatible, could usher in new, faster information-processing paradigms. One potential application is in neuromorphic computing, which aims to replicate the neuronal cells in the body responsible for everything from behavior to memories.
IBM has found a way to speed up some quantum computing tasks by 100 times, finishing them in hours rather than months.
Scientists have developed a new kind of cryogenic computer chip capable of functioning at temperatures so cold, it approaches the theoretical limit of absolute zero.
ABS is partnering with Telemedia, a broadcasting and teleport service provider in South Africa, to improve its service offerings to customers in the Middle East and Africa region (MEA). ABS announced Monday that the company will gain access to a full suite of telecom services provided by Telemedia at its Johannesburg teleport. Telemedia will provide teleport fiber connectivity, data center hosting, and satellite uplink capabilities.
Telemedia said the partnership enables the company to further expand its broadcast and satellite connectivity services in the MEA.
“Our collaboration with Telemedia reinforces and strengthens our presence in the MEA and provides an extension to our global connectivity network,” Ron Busch, ABS’ EVP Engineering and Operations said. “[Telemedia’s] infrastructure offering with a solid track record, excellent customer support and can-do attitude during the COVID-19 pandemic shows its commitment to excellent customer service.”
Cloud computing is at a critical juncture. Millions of companies now use it to store data and run applications and services remotely. This has reduced costs and sped operations. But a new trend threatens the benefits that cloud computing has unlocked.
“Digital sovereignty” describes the many ways governments try to assert more control over the computing environments on which their nations rely. It has long been a concern in supply chains, affecting the kinds of hardware and software available in a given market. Now it’s coming for the cloud.
Governments around the world are passing measures that require companies to host infrastructure and store certain kinds of data in local jurisdictions. Some also require companies that operate within their borders to provide the government with access to data and code stored in the cloud.
Formic ventures — taking on huge challenges — from virtual reality technologist to longevity biotechnology investor.
Michael Antonov is the Founder and CEO of The Michael Antonov Foundation (https://antonovfoundation.org/), a charitable organization that supports biotechnology research and various causes that improve well being of people around the world, as well as Formic Ventures (https://formic.vc/index.html), an early stage high tech and biotech investment firm focused on prolonging human healthspan and empowering human creativity.

Prior to launching the foundation, Michael was a technology executive, most recently as the co-founder and Chief Software Architect at Oculus, acquired by Facebook, where he helped revive the virtual reality industry. Prior to that, Michael was the co-founder and CTO of Scaleform, a user interface software company, whose product is embedded into hundreds of computer, console, and mobile games around the world.
Michael is a graduate of the University of Maryland in the field of computer science and is a member of their alumni hall of fame.
Quantum computing offers the promise of solutions to previously unsolvable problems, but in order to deliver on this promise, it will be necessary to preserve and manipulate information that is contained in the most delicate of resources: highly entangled quantum states. One thing that makes this so challenging is that quantum devices must be ensconced in an extreme environment in order to preserve quantum information, but signals must be sent to each qubit in order to manipulate this information—requiring, in essence, an information superhighway into this extreme environment. Both of these problems must, moreover, be solved at a scale far beyond that of present-day quantum device technology.
Microsoft’s David Reilly, leading a team of Microsoft and University of Sydney researchers, has developed a novel approach to the latter problem. Rather than employing a rack of room-temperature electronics to generate voltage pulses to control qubits in a special-purpose refrigerator whose base temperature is 20 times colder than interstellar space, they invented a control chip, dubbed Gooseberry, that sits next to the quantum device and operates in the extreme conditions prevalent at the base of the fridge. They’ve also developed a general-purpose cryo-compute core that operates at the slightly warmer temperatures comparable to that of interstellar space, which can be achieved by immersion in liquid Helium. This core performs the classical computations needed to determine the instructions that are sent to Gooseberry which, in turn, feeds voltage pulses to the qubits. These novel classical computing technologies solve the I/O nightmares associated with controlling thousands of qubits.
Quantum computing could impact chemistry, cryptography, and many more fields in game-changing ways. The building blocks of quantum computers are not just zeroes and ones but superpositions of zeroes and ones. These foundational units of quantum computation are known as qubits (short for quantum bits). Combining qubits into complex devices and manipulating them can open the door to solutions that would take lifetimes for even the most powerful classical computers.
