Attacking bitcoin mining with a quantum computer would require the energy of a star, academics say

Attacking bitcoin mining with a quantum computer would require the energy of a star, academics say.

• Quantum computing headlines increasingly suggest bitcoin is on the verge of collapse, with claims that future machines could crack its cryptography in minutes or overwhelm the network entirely
• But academic research paints a more constrained picture
• Some widely cited "breakthroughs" rely on simplified problems that don't reflect real-world cryptography
