Quantum Tunnelling Explained: How Particles Cross Energy Barriers
Quantum tunnelling lets a particle cross a barrier it does not have the energy to climb. It is why uranium decays, why the Sun can shine at a mere 15…

Logical Qubits Explained: Why Physical and Logical Qubit Counts Don’t Compare
Quantinuum reports 48 logical qubits built from 98 physical ones. Google's Willow result used 101 physical qubits to make one. IBM reports 70. All three numbers are correct. All three…

Watching Mass Form in Real Time: How Quantum Chips Are Simulating Particle Physics
Between early 2025 and mid-2026, quantum processors have gone from simulating toy models of particle physics to watching confinement, string breaking, and hadron scattering play out in real time. These…
