Major Progress Made Towards Developing Quantum Computers

Quantum computers will have a significant effect on society when researchers complete developmental advances on them. They will have the ability to improve the design of pharmaceutical drugs, increase the power of artificial intelligence, increase the accuracy of predicting weather patterns, and do other things such as improve the analysis of data.

A team of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or “qubits.”

The system marks a major step toward building large-scale quantum machines that could be used to shed light on a host of complex quantum processes and eventually help bring about real-world breakthroughs in material science, communication technologies, finance, and many other fields, overcoming research hurdles that are beyond the capabilities of even the fastest supercomputers today. Qubits are the fundamental building blocks on which quantum computers run and the source of their massive processing power.

“This moves the field into a new domain where no one has ever been to thus far,” said Mikhail Lukin, the George Vasmer Leverett Professor of Physics, co-director of the Harvard Quantum Initiative, and one of the senior authors of the study published today in the journal Nature. “We are entering a completely new part of the quantum world.”

According to Sepehr Ebadi, a physics student in the Graduate School of Arts and Sciences and the study’s lead author, it is the combination of system’s unprecedented size and programmability that puts it at the cutting edge of the race for a quantum computer, which harnesses the mysterious properties of matter at extremely small scales to greatly advance processing power. Under the right circumstances, the increase in qubits means the system can store and process exponentially more information than the classical bits on which standard computers run.

“Our work is part of a really intense, high-visibility global race to build bigger and better quantum computers,” said Tout Wang, a research associate in physics at Harvard and one of the paper’s authors. “The overall effort [beyond our own] has top academic research institutions involved and major private-sector investment from Google, IBM, Amazon, and many others.”

The researchers are currently working to improve the system by improving laser control over qubits and making the system more programmable. They are also actively exploring how the system can be used for new applications, ranging from probing exotic forms of quantum matter to solving challenging real-world problems that can be naturally encoded on the qubits.

News Delivered With Humor Makes It More Memorable

A recent study has been done on how to make news content more memorable. The study’s findings may apply to some other types of content too.

In the early decades of televised news, Americans turned to the stern faces of newsmen like Walter Cronkite, Tom Brokaw, and Dan Rather as trusted sources for news of the important events in America and around the world, delivered with gravitas and measured voices. The rise of comedy-news programs, helmed by the likes of Jon Stewart, Stephen Colbert, John Oliver, Trevor Noah, and Samantha Bee, raised concerns over the blending of entertainment and news. But could the merging of humor and news actually help inform the public?

In fact, new research suggests that humor may help keep people informed about politics. A study from the Annenberg School for Communication at the University of Pennsylvania and the School of Communication at Ohio State University found that, when compared to non-humorous news clips, viewers are not only more likely to share humorously presented news but are also more likely to remember the content from these segments.

“For democracy to work, it is really important for people to engage with news and politics and to be informed about public affairs,” says senior author Emily Falk, Professor of Communication, Psychology, and Marketing at Annenberg. “We wanted to test whether humor might make news more socially relevant, and therefore motivate people to remember it and share it.”

The researchers recruited young adults (18-34 years old) to watch a variety of news clips, which they designed to vary, so that some ended with jokes and others did not. In addition to collecting data on participants’ brain activity using fMRI technology, the researchers administered a memory test to determine how much information participants retained from watching the clips. The researchers also asked participants to answer questions about how likely they would be to share the news clips with others.

Participants were more likely to remember information about politics and government policy when it was conveyed in a humorous rather than non-humorous manner and were more willing to share the information online. The findings also show that humorous news clips elicited greater activity in brain regions associated with thinking about what other people think and feel, which highlights the social nature of comedy.

“Our findings show that humor stimulates activity in brain regions associated with social engagement, improves memory for political facts, and increases the tendency to share political information with others,” says lead author Jason Coronel, Assistant Professor of Communication at OSU. “This is significant because entertainment-based media has become an important source of political news, especially for young adults. Our results suggest that humor can increase knowledge about politics.”

The Importance of Using Different Language for Political Messaging Effectiveness

Language can be used as a method of influencing or controlling thought. I have my disagreements with the cognitive linguist Lakoff, but he does present a useful analysis on why it’s important to use different language to defeat the extreme right-wing in political messaging. One example is that he tells progressives to avoid the phrase “death tax” when referring to the estate tax, instead recommending the counter be the “billionaire’s tax” since less than 0.002% of people will have to pay it. According to Lakoff, this is how the negative connotation to taxing extreme wealth can be countered.

Without knowing it, many Democrats, progressives and members of the news media help Donald Trump every day. The way they help him is simple: they spread his message.

Think about it: every time Trump issues a mean tweet or utters a shocking statement, millions of people begin to obsess over his words. Reporters make it the top headline. Cable TV panels talk about it for hours. Horrified Democrats and progressives share the stories online, making sure to repeat the nastiest statements in order to refute them. While this response is understandable, it works in favor of Trump.

When you repeat Trump, you help Trump. You do this by spreading his message wide and far.

Nobody knows this better than Trump. Trump, as a media master, knows how to frame a debate. When he picks a fight, he does so deliberately. He tweets or says outrageous things, knowing they will be repeated millions and millions of times. When the news media and Democrats repeat Trump’s frames, they are strengthening those frames by ensuring that tens of millions of Americans hear them repeated over and over again.

Quick: don’t think of an elephant. Now, what do you see? The bulkiness, the grayness, the trunkiness of an elephant. You can’t block the picture — the frame — from being accessed by your unconscious mind. As a professor of brain science, this is the first lesson I give my students. It’s also the title of my book on the science of framing political debates.

The key lesson: when we negate a frame, we evoke the frame. When President Richard Nixon addressed the country during Watergate and used the phrase “I am not a crook,” he coupled his image with that of a crook. He established what he was denying by repeating his opponents’ message.

This illustrates one of the most important principles of framing a debate: When arguing against the other side, don’t use their language because it evokes their frame and not the frame you seek to establish. Never repeat their charges! Instead, use your own words and values to reframe the conversation.
