Temporal Mechanics Redefined: The Emergent Nature of Time and Its Implications for Reality

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.

Quantum Annealing in the NISQ Era: Railway Conflict Management

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.

Scientists measure quantum geometry of electrons for the first time

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.
