Programming quantum computers require awareness of entanglement, the phenomenon in which measurement outcomes of qubits are correlated. Entanglement can determine the correctness of algorithms and the suitability of programming patterns.
Entangled qubits give rise to Einstein’s characterization of “spooky action at a distance.” But that potency is equal parts a source of weakness. While programming, discarding one qubit without being aware of its entanglement with one more qubit can obliterate the information put away in the other, endangering the accuracy of the program.
MIT scientists have created their programming language for quantum computing. This new language, called Twist, can describe and verify which pieces of data are entangled in a quantum program.
To create this new language, scientists used a concept called Purity. It enforces the absence of entanglement and results in more intuitive programs, with ideally fewer bugs.
Charles Yuan, an MIT Ph.D. student in electrical engineering and computer science and the lead author of a new paper about Twist, said, “Our language Twist allows a developer to write safer quantum programs by explicitly stating when a qubit must not be entangled with another. Because understanding quantum programs requires understanding entanglement, we hope that Twist paves the way to languages that make the unique challenges of quantum computing more accessible to programmers.” READ MORE...
Fifteen years ago, or 2007 to be more precise, I was diagnosed with non-Hodgkin's Lymphoma or SLL and in 2008 started treatment being infused with a drug called RITUXAN. Two years later, I had a silent heart attack and instead of having a triple bypass, I had 5 stents inserted into 3 left heart ateries, 3 of which went into the LAD. In 2012, and quite possibly because of my cancer treatments, I contracted Melanoma which started in my foot, spread to my groin, and then to my neck.
Over the course of my cancer treatments, I have had chemotherapy, surgery, radiation, and immunotherapy to simultaneously control my two cancers. I am not eligible for any clinical trials because I am battling two cancers simultaneously. Currently, I am being treated with immunotherapy drugs:
Opdivo infusions for my Melanoma - monthly infusions
Imbruvica (pills) - 240 mg daily
IVIG infusions to help boost my immune system
This past Thursday, I had my 55th Opdivo infusion and so far there have been no adverse side effects except for night sweats, anemia, low immunity, and fatigue. My body seems to be tolerating it fairly well according to what my Oncologist said during our office visit.
On Monday morning, I go in for my monthly infusion of IVIG to help boost my immune system and according to my Oncologist, there is no reason why I cannot have both infusions on the same day... which is what I will be doing from now on starting in February. I will have my morning infusion, then go to the cafeteria at the hospital, grab a bite to eat, surf the web, and go to my second infusion an hour or so later and be home by 4/5 that afternoon. Long day, but don't have to go twice.
As far as I can tell, I will be taking some sort of cancer treatments for the rest of my life, even if the doctors are confident that the Melanoma has left my body and is not returning... because my SLL is the type Lymphoma that never leaves one's body once it is there. What a pisser...
Exhibiting emotional intelligence is more important than ever in the workplace. We are in the midst of the Great Resignation, and people are increasingly less likely to stick with jobs where they do not feel seen, heard, or valued.
Employees want to work with and for people who exhibit high degrees of emotional intelligence—teammates and managers who project leadership along with self-awareness, empathy, and humility.
The cornerstone of emotional intelligence is the ability to perceive, evaluate, interpret, and manage emotions—both your own and those of others—and use those insights to drive positive action.
This sensibility can improve everything from communication and personal relationships to effectiveness and job satisfaction. Here are some key phrases that are used by emotionally intelligent leaders.
“I’m listening” / “I hear you”
Never underestimate the power of telling someone you’re listening. We’ve all been on the receiving end of barely-made eye contact or lukewarm nodding while we’re mid-sentence with another person.
How much more validated and valued would we feel if they confirmed we have their undivided attention with some eye contact and a simple “I’m listening”? READ MORE...
LOS ANGELES -- The descendants of Native American tribes on the Northern California coast are reclaiming a bit of their heritage that includes ancient redwoods that have stood since their ancestors walked the land.
Save the Redwoods League planned to announce Tuesday that it is transferring more than 500 acres (202 hectares) on the Lost Coast to the InterTribal Sinkyone Wilderness Council.
Priscilla Hunter, chairwoman of the Sinkyone Council, said it’s fitting they will be caretakers of the land where her people were removed or forced to flee before the forest was largely stripped for timber.
“It’s a real blessing,” said Hunter, of the Coyote Valley Band of Pomo Indians. “It’s like a healing for our ancestors. I know our ancestors are happy. This was given to us to protect.”
The transfer marks a step in the growing Land Back movement to return Indigenous homelands to the descendants of those who lived there for millennia before European settlers arrived. READ MORE...
Those who were paying close attention to a study released by the UK National Health Service might have gotten excited about their latest find.
The study's report showed a correlation between those who consume certain kinds of wine and their likelihood for contracting COVID-19.
Though it might be tempting to jump to the conclusion that drinking some wine could help ward off the highly-transmittable virus, that isn't exactly what the study suggests (via Wine-Searcher).
The study found that those who do not drink at all were more likely to get COVID-19 while those who drink liquor had no more or less of a chance of contracting the virus.
But the key findings were that those who drank 14 glasses of red wine or fewer per week were 10 to 17% less likely to get COVID-19. The same number of glasses of fortified wine reduced the risk by 12%.
Those who drank white wine or Champagne were up to 8% less likely to get the virus. However, it is vital to remember that these figures were reported as correlative patterns, rather than the direct effect of alcohol on COVID-19. READ MORE...
As icebergs drifted by his Antarctica-bound ship, David Holland spoke this week of how the melting glacier he’s cruising towards may contain warning signals for the coasts of far-off Canada.
The atmospheric and ocean scientist from Newfoundland is part of an expedition to one of the world’s most frigid and remote spots – the Thwaites glacier in the western portion of the continent – where he’ll measure water temperatures in an undersea channel the size of Manhattan.
“The question of whether sea level will change can only be answered by looking at the planet where it matters, and that is at Thwaites,” said Holland, director of the environmental fluid dynamics laboratory at New York University, during a satellite phone interview from aboard the South Korean icebreaker Araon.
It’s over 16,000 kilometres from Holland’s hometown in Brigus, N.L., on Conception Bay, to the site about 100 kilometres inland from the “grounding zone” where the Thwaites’ glacier leaves the continent and extends over the Pacific.
The team’s 20,000 tonnes of drilling gear will be assembled to measure the temperatures, salinity and turbulence of the Pacific waters that have crept underneath and are lapping away at the guts of the glacier.
“If it (the water) is above freezing, and in salt water this means above -2 centigrade, that’s not sustainable. A glacier can’t survive that,” said Holland.
Since 2018, more than 60 scientists from the International Thwaites Glacier Collaboration group have been exploring the ocean and marine sediments, measuring warming currents flowing toward the deep ice, and examining the stretching, bending, and grinding of the glacier over the landscape below.
The Florida-sized Thwaites glacier faces the Amundsen Sea, and researchers have suggested in journal articles over the past decade it may eventually lose large amounts of ice because of deep, warm water driven into the area as the planet warms. Some media have dubbed Thwaites the “doomsday glacier” due to estimates that it could add about 65 centimetres to global sea level rise. READ MORE...
Ransomware — malware that prevents you from accessing your files unless you pay the hacker that infected your computer — has been an issue plaguing computer users and businesses for years. Given its prevalence and the fact that a ransomware infection can lead to the loss of valuable files like documents or family pictures, it’s a good idea to make sure you’re protected. Starting with Windows 10, Microsoft has added features to its built-in Windows Security software that can help keep your computer safe from ransomware.
As far as ransomware is concerned, there are two levels to Windows Security. The first consists of malware scans, which are on by default, and which you can learn more about here. While this will work to keep ransomware from being installed on your computer, if a piece of malware does manage to slip by, the scans won’t be able to protect your files.
The second level is Windows’ ransomware protection, which you have to turn on manually. However, before you do, it is worth noting that this feature is not on by default for a reason. It works by only letting approved apps make changes to your files — which, in theory, prevents ransomware from encrypting them and locking them away. This, however, can cause some problems with apps that aren’t expecting it, so you may have to do some occasional trouble-shooting if you’ve got ransomware protection turned on.
As a result, as we go over how to enable ransomware protection, it’s worth keeping in mind that there will probably be some tinkering involved with this process.
HOW TO TURN ON RANSOMWARE PROTECTION Windows’ built-in ransomware protection is included in its security app. To get to it, either search “Windows Security” from the start menu or go to “Settings”> “Privacy & Security”> “Windows Security.” READ MORE...
The big idea One factor that influences the use of the labels “soft science” or “hard science” is gender bias, according to recent researchmycolleaguesand I conducted.
Women’s participation varies across STEM disciplines. While women have nearly reached gender parity in biomedical sciences, they still make up only about 18% of students receiving undergraduate degrees in computer science, for instance.
In a series of experiments, we varied the information study participants read about women’s representation in fields like chemistry, sociology and biomedical sciences. We then asked them to categorize these fields as either a “soft science” or a “hard science.”
Across studies, participants were consistently more likely to describe a discipline as a “soft science” when they’d been led to believe that proportionally more women worked in the field. Moreover, the “soft science” label led people to devalue these fields – describing them as less rigorous, less trustworthy and less deserving of federal research funding.
Why it matters Over the past decade, a growing movement has encouraged girls and women to pursue education and careers in science, technology, engineering and math, or STEM. This effort is sometimes described as a way to reduce the wage gap.
Our research suggests this may not be the case. Stereotypes about women and STEM persist, even in the face of evidence that women can and do productively participate in STEM fields. These stereotypes can lead people to simply devalue the fields in which women participate. In this way, even science and math can end up in the “pink collar” category of heavily female fields that are often devalued and underpaid. READ MORE...
