Fermi-Hubbard op 60 qubits, deel 1: van Hamiltoniaan naar snake-layout en fSWAPs
Een reproduceerbare, kleinere Fermi-Hubbard run laat zien waarom de Q-CTRL aanpak werkt: niet door een generieke compiler, maar door fysica, fermionische mapping, fSWAPs en een hardwarebewuste snake-layout samen te ontwerpen.
Black-Hole Information, OLE, and an 80-Qubit Echo Signal
Stephen Hawking’s black-hole information problem is one of the most famous puzzles in modern physics. If a black hole evaporates, what happens to the information that fell in? The modern answer is…

How I Saved the planet from global warming (with a quantumcomputer)
How it started. ——————————————————————————————————————– “The greatest threat to our planet is the belief that someone else will save it.” — Robert Swan ——————————————————————————————————————– I remember the day vividly. The news was abuzz…
Vibrational Structure Calculation: CO2 Ground state, stretching and bending modes
The molecular Hamiltonian, which governs the behavior of molecules, can be simplified using the Born-Oppenheimer approximation. This approximation is crucial because it decouples the movement of nuclei and electrons due to their…
