At its core, DFT postulates that the ground-state energy of a quantum system is a functional of the electron density. This principle, known as the Hohenberg-Kohn theorem, simplifies the problem of ...

Quantum computing is coming. But the question remains: when does it stop being over the horizon and will it be useful?

Quantum Fourier transform, an important tool in quantum computing, can convert quantum states between different basis vectors, providing a rich dimensional space for information encoding.
