> ELI5: quantum computing HOW DOES IT WORK? Normal Computer 🪙 flat on table 0 OR 🪙 other side up 1 always 0 OR 1 — never both vs Quantum Computer 🪙 spinning! 0 1 0 AND 1 at the same time! this is called a qubit WHY IS IT FASTER? Normal computer tries one path at a time → 😓 slow, one by one ⚡ Quantum tries ALL paths at once → 🚀 explores everything instantly 🪙 Qubit Like a spinning coin — 0 AND 1 until you look at it (then it picks one!) 🌊 Superposition Being in two states at once — like being asleep AND awake (until someone checks!) 🔐 Best for... Passwords, medicine, AI — huge puzzles with tons of answers not for emails or videos! eli5.cc

ELI5: quantum computing

// explanation
// eli5Imagine regular computers use light switches that are either ON or OFF (1 or 0). Quantum computers use special switches that can be ON, OFF, or BOTH at the same time! This magic ability, called superposition, lets them explore many answers super fast, like checking all paths through a maze at once instead of trying one path at a time. [1][2][5]
