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

Hermitian Hamiltonians are a fundamental concept in quantum mechanics, serving as the mathematical foundation for describing the energy and time evolution of quantum systems. They are named after the ...

A new study published in Scientific Reports simulates particle creation in an expanding universe using IBM quantum computers, demonstrating the digital quantum simulation of quantum field theory for ...

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