What do our experience of the flow of time and quantum computing have in common?

Posted by in categories: computing, quantum physics

In the fascinating intersection of quantum computing and the human experience of time, lies a groundbreaking theory that challenges our conventional narratives: the D-Theory of Time. This theory proposes a revolutionary perspective on time not as fundamental but as an emergent phenomenon arising from the quantum mechanical fabric of the universe.

In my upcoming book with a working title Cybernetic Theory, the entire section is dedicated to the physics of time, where we discuss the D-Theory of Time, predicated or reversible quantum computing at large, which represents a novel framework that challenges our conventional understanding of time and computing. Here, we explore the foundational principles of the D-Theory of Time, its implications for reversible quantum computing, and how it could potentially revolutionize our approach to computing, information processing, and our understanding of the universe.

At its core, the D-Theory of Time suggests that time may not be a fundamental aspect of the universe but rather an emergent property arising from the interactions of more basic entities or processes. Time symmetry, in physics, refers to the principle that the fundamental laws governing the universe are invariant, or unchanged, when the direction of time is reversed. Given extra degrees of freedom, time is not a linear, unidirectional flow but a set of dimensions that can be traversed in both directions, akin to spatial dimensions. This perspective aligns with the concept of reversible quantum computing, where operations are not only forward but can also be reversed, preserving quantum information, and potentially enabling universal computations that are far beyond the capabilities of classical computing.

Umbrella for atoms: The first protective layer for 2D quantum materials

Posted by in categories: computing, particle physics, quantum physics

As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science’s biggest challenges.

In a groundbreaking development, researchers at the Würzburg-Dresden Cluster of Excellence have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin within realistic reach. The findings have been published in Nature Communications.

A promising leap towards computers with light-speed capabilities

Posted by in categories: computing, quantum physics

Scientists have created a reprogrammable light-based processor, a world-first, that they say could usher in a new era of quantum computing and communication.

Technologies in these emerging fields that operate at the atomic level are already realizing big benefits for drug discovery and other small-scale applications.

In the future, large-scale quantum computers promise to be able to solve complex problems that would be impossible for today’s computers.

‘Oceans are hugely complex’: modelling marine microbes is key to climate forecasts

Posted by in categories: biological, chemistry, climatology, computing

An interesting exploration of the importance of oceanic microorganisms to biogeochemical processes, how existing computational climate models do not adequately capture the complexity introduced by these microbes, and suggestions for future directions in climate modeling that better incorporate the…


Microorganisms are the engines that drive most marine processes. Ocean modelling must evolve to take their biological complexity into account.

New class of 2D material displays stable charge density wave at room temperature

Posted by in categories: computing, particle physics, quantum physics

Quantum materials have generated considerable interest for computing applications in the past several decades, but non-trivial quantum properties—like superconductivity or magnetic spin—remain in fragile states.

“When designing quantum materials, the game is always a fight against disorder,” said Robert Hovden, an associate professor of materials science and engineering at the University of Michigan.

Heat is the most common form of disorder that disrupts quantum properties. Quantum materials often only exhibit exotic phenomena at very low temperatures when the atom nearly stops vibrating, allowing the surrounding electrons to interact with one another and rearrange themselves in unexpected ways. This is why quantum computers are currently being developed in baths of liquid helium at −269 °C, or around −450 F. That’s just a few degrees above zero Kelvin (−273.15 °C).
