Radiofrequency tuning elements made of quantum paraelectric materials are demonstrated at temperatures close to absolute zero — a temperature regime in which conventional electronic tuning components do not work. This advance greatly improves the read-out sensitivity of quantum circuits that require operation at such low temperatures.

使用量子顺电变容二极管将电子电路调谐到接近绝对零


由量子顺电材料制成的射频调谐元件在接近绝对零的温度下得到了证明——在这种温度范围内，传统的电子调谐元件不起作用。这一进步极大地提高了需要在如此低的温度下运行的量子电路的读出灵敏度。
