Quantum Optimal Control Theory (QOCT) is a rigorous framework that underpins the precise manipulation of quantum systems by designing tailored control fields. It combines advanced mathematical ...

Quantum control encompasses the advanced techniques employed to manipulate and steer quantum systems towards desired outcomes. Within this field, adiabatic processes have long served as a robust ...

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

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

The problem with quantum mechanics, or at least the reason even physicists don’t understand it, isn’t that it paints an unfamiliar picture of reality. It isn’t difficult to accept that the world of ...
