Elon Musk Backs the Physics Behind a Claim Quantum Computers Can't Break Bitcoin
Elon Musk has backed a fringe physics theory that says quantum computers can only grow so big. Crypto traders turned his five word reply into proof that Bitcoin (BTC) is already safe from them.
But it is not proof. The theory comes from Oxford physicist Tim Palmer, predicting that quantum machines stall somewhere between 200 and 400 qubits.

He agreed the universe comes in fixed chunks. He said nothing about private keys or Bitcoin's quantum problem. Investor Fred Krueger cited him a day later anyway, under the headline that Bitcoin is already quantum-safe.
"Bitcoin may already be quantum-safe…The latest estimates require at least 835 logical qubits to break Bitcoin's signatures with Shor's algorithm…Elon Musk and Steve Jurvetson have commented positively on this research," he said.
