What if our understanding of time as a linear sequence of events is merely an illusion created by the brain’s processing of reality? Could time itself be an emergent phenomenon, arising from the complex interplay of quantum mechanics, relativity, and consciousness? How might the brain’s multidimensional computations, reflecting patterns found in the universe, reveal a deeper connection between mind and cosmos? Is it possible that advancements in our understanding of temporal mechanics could one day make time travel a practical reality rather than a theoretical concept? Could Quantum AI and Reversible Quantum Computing provide the tools to simulate, manipulate, and even reshape the flow of time, offering practical applications of D-Theory that bridge the gap between theoretical physics and transformative technologies? These profound questions lie at the heart of Temporal Mechanics: D-Theory as a Critical Upgrade to Our Understanding of the Nature of Time, my 2025 paper and book. D-Theory, also referred to as Quantum Temporal Mechanics, Digital Presentism, and D-Series, challenges conventional views of time as a fixed, universal backdrop to reality and instead redefines it as a dynamic interplay between the mind and the cosmos.
We are in the noisy intermediate-scale quantum (NISQ) devices’ era, in which quantum hardware has become available for application in real-world problems. However, demonstrations of the usefulness of such NISQ devices are still rare. In this work, we consider a practical railway dispatching problem: delay and conflict management on single-track railway lines. We examine the train dispatching consequences of the arrival of an already delayed train to a given network segment. This problem is computationally hard and needs to be solved almost in real time. We introduce a quadratic unconstrained binary optimization (QUBO) model of this problem, which is compatible with the emerging quantum annealing technology. The model’s instances can be executed on present-day quantum annealers.
The geometry or shape of a quantum system is mathematically expressed by a tool called the quantum geometric tensor (QGT). It also explains how a quantum system’s state changes when we tweak certain parameters such as magnetic field or temperature.
For the first time, researchers at MIT have successfully measured the QGT of electrons in solid materials. Scientists have been well aware of the methods to calculate the energy and motion of electrons, but understanding their quantum shape was only possible in theory until now.

With so much fascinating research going on in quantum science and technology, it’s hard to pick just a handful of highlights. Fun, but hard. Research on entanglement-based imaging and quantum error correction both appear in Physics World’s list of 2024’s top 10 breakthroughs, but beyond that, here are a few other achievements worth remembering as we head into 2025 – the International Year of Quantum Science and Technology.
Quantum sensing
In July, physicists at Germany’s Forschungszentrum Jülich and Korea’s IBS Center for Quantum Nanoscience (QNS) reported that they had fabricated a quantum sensor that can detect the electric and magnetic fields of individual atoms. The sensor consists of a molecule containing an unpaired electron (a molecular spin) that the physicists attached to the tip of a scanning-tunnelling microscope. They then used it to measure the magnetic and electric dipole fields emanating from a single iron atom and a silver dimer on a gold substrate.
A quantum state of light has been successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.
The impressive demonstration by researchers in the US may not help you beam to work to beat the morning traffic, or download your favourite cat videos faster.
However, the ability to teleport quantum states through existing infrastructure represents a monumental step towards achieving a quantum-connected computing network, enhanced encryption, or powerful new methods of sensing.
Einstein’s theory of general relativity describes the inevitability of singularities, which are obscured by black holes according to Penrose’s cosmic censorship conjecture.
Recent studies indicate that quantum mechanics might reinforce this idea, proposing a quantum Penrose inequality that relates entropy to space-time metrics in the vicinity of black holes.

Superradiance in optical cavities involves atoms emitting light collectively when interacting with cavity photons, a phenomenon not yet observed in free space due to synchronization challenges.
Researchers have used theoretical simulations to probe these effects under various conditions, revealing significant differences in behavior between cavity and free-space systems.
