A new era of computing may be upon us as Google claims its Sycamore computer has achieved quantum supremacy (量子霸权). But what is quantum supremacy, and what does it mean for the future?
Quantum supremacy is a scientific term. It means that a quantum computer has solved a problem that a classical computer would take too much time and energy to do.
1. (publish) in the journal Nature on Oct 23, Google tasked a computer with finding mathematical probabilities of different “events”. The events were specific values from a random number generator. Sycamore successfully picked out strings (系列) of numbers that were 2. (likely) to occur than others, running the test 1 million times in 200 seconds.
In their research, Google claims that the world’s best supercomputer would have taken 10,000 years 3.(solve) the same problem. However, Google’s claims were questioned by rival company IBM, who argued the same test 4. have been completed in 2.5 days by its Summit supercomputer.
What is quantum computing? The major difference between quantum and classic computers is in how they record and transmit information. Classic computers, from your laptop to your phone to a NASA supercomputer, use bits. Each bit has a state of either zero or one (on or off) and completes each operation one-at-a-time.
However, quantum computers, like Google’s Sycamore, use quantum bits – called qubits (量子位). These can be both zero and one at the same time, allowing them to hold more data and work together to solve problems simultaneously.
Google’s experiment has been applauded 5. a major breakthrough. It is a stepping-stone toward a big dream.
Currently, quantum computers are within the next decade. Tech reporter Jacob Ward told NBC News, “This could revolutionize our every little real-world value, but that can all change whole lives. We’re talking about the development of new medicines, materials, artificial intelligence, all of which, right now, 6. (depend) on a very limited language of computing.?”
While quantum may not be close to 7. (change) our everyday lives right now, it has been compared to the first rocket to reach space. It may be a generation 8. quantum computers become mainstream, so who can say what humans might achieve with the new technology?

In the United States, engineering is a profession that has been dominated historically by men. Even today, it’s still true that few women become civil or chemical or mechanical engineers, but that’s something www.EngineerGirl.org aims to change. Young women who visit the web site can find out about a great career choice they might not have considered.
“Women are very much underrepresented in engineering and in engineering education programs and then of course, down the road, in the engineering workforce. So only about 20 percent of engineering undergraduate degrees go to women, and then only about nine percent of working engineers are women.”
Mary Mattis in the National Academy of Engineering says the EngineerGirl website aims to reach young women around ages 11 through 14, when they are just getting old enough to start thinking about their futures.
“We know from the research that middle-school girls are at a critical point in their lives, and that it’s a time when we need to reach them, both with an understanding, increasing their awareness of interesting fields in engineering, what a wonderful productive and exciting career you can have as an engineer. But we also need to reach them at that time because you have to take certain courses, and you can’t start thinking about taking those courses when you’re a junior in high school.”
Engineering is a demanding course of study — there is a lot of science and mathematics, for many girls and even boys, that can be challenging. But Ms. Mattis says that the EngineerGirl website stresses that engineering can also be fun and exciting.
“It’s about designing things. It’s about changing the world for people. It’s about making a difference. And, in addition, you can make a good living; you can be independent economically by becoming an engineer. All of those things are messages that girls need to get.”
While most engineers go into traditional fields such as mechanical and electrical engineering, the EngineerGirl site also highlights unusual engineering careers in fields such as sports engineering and — believe it or not — chocolate engineering.
“There’s a section called ‘why be an engineer,’ and that talks about the many opportunities and increasingly different opportunities like with bio-engineering and environmental engineering, some fields that might appeal to girls who want to make a difference or have a meaning for their careers beyond earning an income.”Even if you are not a girl in the target age group, there’s a lot of interesting information on the site, including biographies of some notable women engineers.

Partway through Wonder, Fifth-grader Auggie Pullman finds himself seated across from a new friend in the school cafeteria. “Have you ever thought about having plastic surgery?” the friend asks.
“Dude, this is after plastic surgery. It takes a lot of work to look this good,” Auggie says, running a hand through his hair. In other words, what could be painfully depressing turns out to hold lurking(潜藏的) reserves of humour, which is pretty much the story of Wonder.
Auggie, played by Jacob Tremblay, was born with a facial difference, and even after multiple operations, his looks shock his classmates. As he adapts from homeschooling to a new school community, he encounters far worse than that lunchtime scene－one nasty bully(横行霸道者) says he’d kill himself if he looked like Auggie－but he never fully loses heart.
The movie is an adaptation of the 2012 novel by R.J.Palacio, which has sold 6 million copies in North America and launched an antibullying campaign, Choose Kind. Palacio has said she got the idea for the story when her young son began crying at the sight of a girl with a facial difference in an ice cream shop. She took her kids out of the shop, but later regretted her reaction. “What I should have done is simply turned to the little girl and started up a conversation and shown my kids that there was nothing to be afraid of,” she said.
Tremblay, 11, who broke out opposite Brie Larson in the 2015 drama Room, has more than a few things in common with Auggie. “We both love Star Wars, we have awesome families, and we love our dogs.” But Tremblay thinks we all can find something in common with the boy. “Everyone’s like Auggie in one very important way: we want to be accepted and treated equally and with kindness.”
Julia Roberts, who plays Auggie’s mother, became interested in the part because of her own children, “I read it with my kids and fell so in love with it,” she says of the novel. “This book is such a beautiful and gentle introduction into all kinds of topics, including bullying and intolerance and fear, and what fear makes young people do sometimes.”
Both actors have some familiarity with the subject. “I was picked on quite a bit as a young person,” Roberts says, though she won’t say what for. “Even as a 50-year-old mother of three, it’s not a path I like to go up and down.” Tremblay reveals a bit more. “I have been picked on,” he says, “because I’m kind of short for me age. I told my parents, and that’s one of the best things you can do, because my mom said would never want me to carry negative thoughts on my shoulders alone.”
The most challenging parts of filming, says Tremblay, were moments in which he had to cry. Tenderhearted audience members will likely shed tears of their own－especially during scenes between Auggie and his mom, who repeatedly reassures her son that he is worthy of love. But the movie also has its fair share of hijinks(喧闹): for every tear-filled moment, there is a lightsaber battle or silly science project to lighten the mood. This mixture of pity and humor, says Roberts, “was intrinsic(固有的) in the writing in the novel.” But she credits writer-director Stephen Chbosky with translating that balance into visual terms.
As much as the movie impresses the viewer with compassion for the underdogs, it also finds a way to sympathize with the bullies. “I would say to try to take a moment to be conscious of why a person that is bullying somebody is behaving that way,” says Roberts, “After all”, she adds, “There’s no child that’s born bully.”
