= Dilution refrigerator
{wiki}
Reaches 2 mKhttps://en.wikipedia.org/wiki/Dilution_refrigerator{ref}. https://youtu.be/upw9nkjawdy?t=487 from <video Building a quantum computer with superconducting qubits by Daniel Sank (2019)> mentions that 15 mK are widely available.
Used for example in some times of <quantum computers>, notably <superconducting quantum computers>. As mentioned at: https://youtu.be/uPw9nkJAwDY?t=487[], in that case we need to go so low to reduce thermal noise.
