Quantum Decoherence: Why the Quantum World Looks Classical
Nothing in quantum mechanics forbids a cat from being alive and dead at once. Superposition has no size limit written into the theory, and yet nobody has ever seen a…

How Quantum Error Correction Works
You cannot copy a qubit to protect it, and you cannot look at it to check on it, since both acts destroy the information you are trying to save. Quantum…

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…

Breaking RSA-2048: Why the Estimate Fell From 20 Million to 10,000 Qubits
In 2019 the reference estimate for breaking RSA-2048 was 20 million noisy qubits running for eight hours. In March 2026 a Caltech and Oratomic team put the figure at 10,000.…

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.
