  • These qubits oscillate at microwave frequencies where the quantum information is stored. This means they need to be kept at a temperature where the microwave frequencies are completely devoid of any thermal noise. For microwave frequencies, this temperature is just a few millikelvins above absolute zero. Unfortunately, the temperature is required due to the fundamental nature of thermal noise due to temperature. Making the qubits out of room temperature superconductor would not solve the problem of the need to cool them down - unless they can be operated at higher frequency. There are quantum computers made using light/optical photons which do operate at room temperature because optical photons are at much higher frequency which has no thermal noise even at room temperature.

    So, in conclusion, everytime you hear about superconducting qubit, they are always in a giant dilution refrigerator which gets bigger for more qubits as more connections from room temperature to qubits are needed.











  • I would still say it’s an asshole design. They are trying to copy a well established internet Design Trend where a ‘Not Now’ sort of a button is slightly greyed out near the advertisement. I would assume the next trick would be to sneakily add the prime fees in the total and some unsuspecting user would fall for it. Not to mention, the whole fiasco of how hard Amazon made it to cancel the prime subscription. Fuck these companies.
