How a Quantum Computer Evaluates Financial Risks ⚡ экспресс
Surprising fact: a quantum computer can assess how much a bank might lose on an exotic contract a year from now, hundreds of times faster. Scientists built a hybrid scheme: a classical computer sketches the picture, while the quantum one refines rare catastrophic scenarios. The error is just 1–8%. For now, simulators are needed, but in a few years, 300 qubits will handle such a week-long task in an instant.
🎯 A qubit — a quantum cell — combines zero and one, like a coin spinning without falling. This trick allows the computer to process multiple scenarios at once and find an answer in a flash where a regular one would take years.
🎬 This resembles psychohistory from Asimov’s 'Foundation' — a mathematics that predicts the fates of civilizations. Only here, instead of galaxies, it’s stock markets.
