The breakthrough in mobile silicon spin qubits with 99% fidelity and teleportation accelerates the timeline for fault-tolerant quantum computers. For crypto, this reinforces the long-term existential risk to elliptic curve cryptography (used in BTC/ETH) but also highlights a growing investment thesis for quantum-resistant protocols. Mainstream media will hype 'quantum threat,' but the reality is that breaking Bitcoin's ECDSA still requires millions of physical qubits—decades away.

Nature publishes research demonstrating two-qubit gate fidelity of about 99% and quantum state teleportation between mobile spin qubits in silicon separated by 320 nm.
