【文章概要】量子计算机芯片在有史以来的最高温度下展示了量子计算机芯片。
Quantum computer chips demonstrated at the highest temperatures ever
Quantum computing isheating up. For the first time, quantum computer chips (1) ______ (operate) ata temperature above -272°C, or 1 kelvin. That may still em frigid, but it isjust warm enough to potentially enable a huge leap in the capabilities.
Quantum computers aremade of quantum bits, or qubits（量子比特）, (2) ______ can be made inveral different ways. One that (3) ______(receive) attention from some of the field’s big players consists of electronson a silicon chip.
The systems onlyfunction at extremely low temperatures -below 100 millikelvin, or -273.05°C-so the qubits have to be stored in powerful refrigerators. The electronics thatpower them won’t run at such low temperatures, and also emit heat that coulddisrupt th
e qubits, so (4) ______ are generally stored outside therefrigerators with each qubit is connected by a wire to its electroniccontroller.
“Eventually, foruful quantum computing, we will need to go to something like a millionqubits, and this sort of brute force method, with one wire per qubit, won’twork any more,” says Menno Veldhorst at QuTech in the Netherlands. “It worksfor two qubits, but not for a million.”
Veldhorst and hiscolleagues, (5) ______ _______ another team led by rearchers at theUniversity of New South Wales in Australia, have now demonstrated that thequbits can be operated at (6) ______ (high) temperatures. The latter team showed they were able to control the state of two qubitson a chip at temperatures up to 1.5 kelvin, and Veldhorst’s group ud twoqubits at 1.1 kelvin in (7) ______ is called a logic gate, which performs thebasic operations that make up more complex calculations.
(8) ______ ______ weknow the qubits themlves can function at higher temperatures, the next stepis incorporating the electronics onto the same chip. “I hope that (9) ______
wehave that circuit, it won’t be too hard to scale to something with practicalapplications,” says Veldhorst.
Tho quantumcircuits will be similar in many ways to the circuits we u for traditionalcomputers, so they can be scaled up relatively easily (10) ______ (compare) withother kinds of quantum computers, he says.

量子计算正在升温。量子计算机芯片首次在-272℃，即1开尔文以上的温度下运行。这个温度看起来还是很冷，但也仅仅是足够温暖，有可能实现能力上的巨大飞跃。
