Nothing physical is transported. No faster-than-light communication. Quantum teleportation transfers information using entanglement — and it's essential for quantum networks.

'We have 1,000 qubits' means nothing without context. Here's a framework for evaluating quantum hardware claims — the numbers that matter, the ones that don't, and the red flags.

17 developments this month signal a real shift: fault-tolerant logical qubits, 100km quantum networks, and GPU integration. The 'horsepower era' is ending. Here's what's replacing it.
Read article →Quantum Computing Inc. and Ciena integrate quantum key distribution, quantum identity authentication, and post-quantum cryptography in a commercial telecom platform capable of 1.6 terabit/second encrypted data transmission.

Superconducting, trapped ion, photonic, neutral atom, topological — five fundamentally different bets on the future of computing. Here's what each one does and why the race is still open.

Error correction is the biggest engineering challenge in quantum computing. The surface code is the leading solution — here's how it works, without the stabilizer math.

A practical reading workflow for non-physicists: what to look for, what to skip, and where papers hide their real assumptions.

Quantum computation isn't 'run once, get answer.' It's 'run thousands of times, average the results, hope the noise doesn't drown the signal.' Here's the cost model.

Every month, someone claims quantum advantage. Here's a framework for evaluating those claims — fairly but sceptically.
Read article → The hype says yes. The truth is more nuanced. Here's what quantum computers can and can't do today, who's using them, and when they'll actually matter.

You write a quantum program as gates on qubits. The hardware runs microwave pulses and laser beams. The gap between these two is called compilation — and it determines whether your algorithm actually works.

Quantum computers aren't better classical computers. They're a completely different tool for completely different problems. Here's what they're actually good at.

Qubits are absurdly fragile. A stray photon, a vibration, even cosmic rays can ruin a computation. Error correction is the single biggest challenge in quantum computing.

Quantum entanglement isn't mystical or faster than light. It's a specific kind of correlation that classical physics can't explain — and it's a tool, not magic.

Forget 'trying all possibilities.' Quantum computing works because wrong answers can cancel themselves out. Here's how.

The most misunderstood concept in computing, explained without the mysticism. A qubit is weirder than '0 and 1 simultaneously' — and more useful.
Read article → The most common misconception about quantum computing is that it's just a speed boost. It's not. It's a fundamentally different way of computing — and for most things, it's actually slower.
