Quantum computer chips demonstrated at the highest temperatures ever
Quantum computing is heating up. For the first time, quantum computer chips (21) ________ (operate) at a temperature above -272℃, or 1 kelvin. That may still seem frigid, but it is just warm enough to potentially enable a huge leap in the capabilities.
Quantum computers are made of quantum bits, or qubits(量子比特), (22) ________ can be made in several different ways. One that (23) ________ (receive) attention from some of the
field's big players consists of electrons on a silicon chip.
These systems only function at extremely low temperatures-below 100 millikelvin, or -273.05℃ -so the qubits have to be stored in powerful refrigerators. The electronics that power them won't run at such low temperatures, and also emit heat that could disrupt the qubits, so (24) ________ are generally stored outside the refrigerators with each qubit is connected by a wire to its electronic controller.
“Eventually, for useful quantum computing, we will need to go to something like a million qubits, and this sort of brute force method, with one wire per qubit, won't work any more,” says Menno Veldhorst at QuTech in the Netherlands. “It works for two qubits, but not for a million.”
Veldhorst and his colleagues, (25) ________ another team led by researchers at the University of New South Wales in Australia, have how demonstrated that these qubits can be operated at (26) ________ (high) temperatures. The latter team showed they were able to control the state of two qubits on a chip at temperatures up to 1.5 kelvin, and Veldhorst's
group used two qubits at 1. I kelvin in (27) ________ is called a logic gate, which performs the basic operations that make up more complex calculations.
(28) ________ we know the qubits themselves can function at higher temperatures, the next step is incorporating the electronics onto the same chip. “I hope that (29) ________ we have that circuit, it won't be too hard to scale to something with practical applications,” says Veldhorst.
Those quantum circuits will be similar in many ways to the circuits we use of traditional computers, so they can be scaled up relatively easily (30) ________ (compare) with other kinds of quantum computers, he says.

Wildfires rage as China's Chongqing suffers unrelenting record heat wave
From: CNN August 23, 2022
Thousands of emergency responders are battling to (31) ________ fast-spreading wildfires in China's southwestern city of Chongqing amid a weeks-long, record heat wave in the region.
The fires, which have been visible at night from parts of the downtown area, have (32) ________ forests and mountains around the mega city in recent days. On social media, residents in downtown Chongqing complained of smelling smoke inside their apartments, while others posted pictures of burning embers from the fires reaching their balconies.
Municipal authorities have not yet reported any casualties and said the fires are being kept under control, according to an update on Tuesday morning. More than 1,500 residents have been (33) ________ to safe zones, while 5,000 firefighters, police, local officers and volunteers, and seen firefighting helicopters have been dispatched to help combat the blazes, state-run Xinhua news agency reported.
The fires in Chongqing were the result of “spontaneous combustion” mainly caused by (34) ________ high temperatures, Bai Ye, a professor at China's Forest and Grassland Fire Prevention and Extinguishing Research Center told state-run Beijing Daily.
The wildfires are another knock-on effect of a crippling heat wave China's worst since 1961 -that has swept through southwestern, central and eastern parts of the country in recent weeks, with temperatures crossing 40 degrees Celsius (104 degrees Fahrenheit) in more than 100 cities.
They are also part of a global trend of wildfires that have ravaged areas from Australia to California, with scientists sort out the factssaying (35) ________ global temperatures due to human-driven climate change increase the risk of these events.
China's heat wave has also brought (36) ________ demand for air conditioning and reductions in hydropower capacity due to drought conditions that have (37) ________ the country's (38) ________ critical Yangtze River and connected waterways.
