What Is a Qubit?
A qubit is not a bit that is somehow both 0 and 1 at once. That line points at the wrong mechanism. A qubit's state is a pair of complex…

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…

Universal Quantum Gates from Anyons: How S3 Topological Computing Works
A quantum processor has run a universal gate set built entirely out of moving exotic quasiparticles around one another and fusing them together. Fifty-four qubits, one phase of matter, three…

The Latest in Quantum Computing: The Advances Reshaping the Field
Error correction crossed the threshold, a quantum advantage became verifiable, and the cost of breaking RSA fell — on maths, not hardware. What actually changed, and what each result promises.
