WHY "MORE QUBITS" ISN'T THE HEADLINE THAT MATTERS 🧯

A plain-English explainer for reading past the hype:

Today's qubits are noisy — they lose their quantum state (decohere) in tiny fractions of a second, and every gate adds a little error. Run a long computation raw and the answer is mush.

The fix is error correction: weave many physical qubits together so they act as ONE reliable "logical" qubit. Depending on hardware quality, one logical qubit can cost hundreds or thousands of physical ones.

So when a headline says "company X hits N qubits", the questions that matter are:
• How good are the gates (error rates)?
• How many LOGICAL qubits does that translate to?
• Can they keep a logical qubit alive longer than the physical ones it's made of?

That last one — logical beating physical — is the real milestone the whole field is racing toward.

WHERE DOES QUANTUM GET USEFUL FIRST? 🎯

Genuine open question — place your bets.

The usual candidates:
• Chemistry & materials — simulating molecules classical computers choke on (batteries, drugs, catalysts)
• Optimization & finance — better routes, portfolios, schedules
• Cryptography — breaking old codes (and the post-quantum scramble that's already underway)
• Machine learning — the most hyped and least proven of the bunch

Our take: chemistry first, because it's the one problem that's quantum-native — you're using a quantum system to simulate a quantum system.
