Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding ...

The 2025 Nobel Prize in physics has been awarded to a trio of scientists – a Briton, a Frenchman and an American – for their ground-breaking discoveries in the field of quantum mechanics. John Clarke, ...

Classical computations rely on binary bits, which can be in either of the two states, 0 or 1. In contrast, quantum computing is based on qubits, which can be 0, 1, or a superposition or entanglement ...

Abstract The theory of quantum states over time extends the density operator formalism into the temporal domain, providing a unified treatment of ...
