Quantum computers require extremely low temperatures, significantly colder than deep space, to maintain the delicate state of qubits. IBM's latest cryogenic systems achieve temperatures below 15 millikelvin, over 180 times colder than deep space, to minimize heat-induced decoherence. This extreme cold is essential because any external energy can disrupt the qubits' quantum states, leading to inaccurate calculations. While dilution refrigerators are common, alternative methods like neutral-atom machines use lasers to cool atoms to microkelvin temperatures, bypassing some of the challenges associated with traditional cryogenic cooling.
