The race to build a quantum computer capable of breaking modern cryptography has always seemed like a contest of scale. The common belief has been that once someone builds a machine with a million high-quality qubits, the door to factoring classical asymmetric cryptography, such as RSA 2048, will swing open. Yet the closer the field gets to that scale, the more it becomes clear that the real obstacle is not the qubits themselves but the physical burden of supporting them. Q CTRL’s recent work
