What Is ‘So You Want to Learn Physics’?

“So You Want to Learn Physics” is a comprehensive guide aimed at demystifying physics for entrepreneurs and innovators. It bridges the gap between theoretical principles and practical tech applications, providing tools for startups to leverage physics in novel ways. Think of it as a manual on how to transform the cryptic equations of quantum mechanics into game-changing tech solutions, much like how Ben Franklin turned lightning into electricity.

How ‘Physics’ Works in Practice

Real-world applications of physics are transforming industries at pace — and it’s not just quantum mechanics. Physics is underpinning moonshot projects from Silicon Valley to Tesla’s labs. Let’s dissect three companies leading the charge.

IBM’s Quantum Computation

IBM’s Quantum Computation group is not just tinkering with qubits for academic delight; they’re catalyzing disruptive advancements. By employing physical principles that govern the microscopic world, they are laying new grounds for computational possibilities. Their quantum processor, Eagle, is a testament, achieving a 127-qubit milestone — far beyond any classical computer’s capacity.

Rigetti Computing’s Quest for Quantum

Rigetti Computing is another formidable player, pushing the envelope of quantum processing technologies. By understanding how atoms interact and govern information, Rigetti offers quantum cloud services that can solve complex problems traditional supercomputers can’t. This isn’t theoretical anymore; it’s computing for the next era, impacting everything from healthcare forecasting to digital security.
