Researchers advance noise cancelling for quantum computers

Posted by in categories: computing, quantum physics

A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, “non-Gaussian” noise processes that are routinely encountered in superconducting quantum computing systems.

The characterization of non-Gaussian noise in superconducting quantum bits is a critical step toward making these systems more precise.

The joint study, published in Nature Communications, could help accelerate the realization of systems. The experiment was based on earlier conducted at Dartmouth and published in Physical Review Letters in 2016.

Mentors, Encouragement, Hands-on Learning Boost Girls’ Interest in STEM Substantially

Posted by in categories: computing, education, employment, engineering, mathematics

Generally girls lose interest in STEM careers as they get older. But, according to a new study, small changes at school and at home can have a profound impact on how girls perceive STEM careers, how confident they feel in class and how likely they are to pursue STEM academically and into their careers.

The study, “Closing the STEM Gap,” published today by Microsoft, surveyed more than 6,000 girls and young women on their interests and perceptions of science, technology, engineering and math. It found that girls tended to lose interest in STEM as they headed toward adulthood. And, by the time they’d finished high school, their interest had dropped substantially. For example, the report found that interest in computer science among females dropped 27 percentage points between middle school and college. According to the report: “In middle school … 31 percent of girls believe that jobs requiring coding and programming are ‘not for them.’ In high school, that percentage jumps up to 40. By the time they’re in college, 58 percent of girls count themselves out of these jobs.”

But, the study found, countermeasures both large and small can have a profound effect, including:

Brain-computer interface: huge potential benefits and formidable challenges

Posted by in categories: computing, neuroscience

A new Royal Society report called “iHuman: blurring lines between mind and machine” is for the first time systematically exploring whether it is “right” or not to use neural interfaces – machines implanted in or worn over the body to pick up or stimulate nervous activity in the brain or other parts of the nervous system. It also sets out recommendations to ensure the ethical risks are understood, and to set up a transparent, public-driven but flexible regulatory framework which will allow the UK to lead innovative technology in this field.

Meet the 8 Tech Titans Investing in Synthetic Biology

Posted by in categories: bioengineering, biotech/medical, computing, food, sustainability

“DNA is like a computer program but far, far more advanced than any software ever created.” Bill Gates wrote this in 1995, long before synthetic biology – a scientific discipline focused on reading, writing, and editing DNA – was being harnessed to program living cells. Today, the cost to order a custom DNA sequence has fallen faster than Moore’s law; perhaps that’s why the Microsoft founder is turning a significant part of his attention, and wallet, towards this exciting field.

Bill Gates is not the only tech founder billionaire that sees a parallel between bits and biology, either. Many other tech founders – the same people that made their money programming 1s and 0s – are now investing in biotech founders poised to make their own fortunes by programming A’s, T’s, G’s and C’s.

The industry has raised more than $12.3B in the last 10 years and last year, 98 synthetic biology companies collectively raised $3.8 billion, compared to just under $400 million total invested less than a decade ago. Synthetic biology companies are disrupting nearly every industry, from agriculture to medicine to cell-based meats. Engineered microorganisms are even being used to produce more sustainable fabrics and manufacture biofuels from recycled carbon emissions.

Brain chips could soon give people superintelligence

Posted by in categories: computing, Elon Musk, neuroscience

Brain-to-computer interfaces and intelligence boosting chips implanted in the brain could soon make their way out of the realms of science fiction and into reality.

Already, some of the biggest tech giants in the industry like Elon Musk and Facebook are working to create brain-computer interfaces.

CBS Chicago recently spoke to Dr. Moran Cerf, a neuroscientist at Northwestern University, who is currently developing a non-invasive computer chip that when implanted in the brain could give an individual super intelligence.

The World’s First Photo of Quantum Entanglement Could Disprove Einstein’s Theory

Posted by in categories: computing, encryption, quantum physics

Einstein dubbed the idea of quantum entanglement as “spooky action at a distance.” Now for the first time ever, scientists have taken a picture of it.

Today we understand quantum entanglement as when a pair of particles that cross paths and interact with each other can become connected and stay that way, even when the particles are spaced very far apart.

Is the Universe Actually a Giant Quantum Computer?

Posted by in categories: computing, engineering, humor, quantum physics, space

According to MIT professor Seth Lloyd, the answer is yes. We could be living in the kind of digital world depicted in The Matrix, and not even know it.

A researcher in Mechanical Engineering at MIT, Lloyd is one of the leaders in the field of quantum information. He’s been with the field from its very conception to its sky-rocketing rise to popularity. Decades ago, the feasibility of developing quantum computing devices was challenged. Now, as quantum computation is producing actual technologies, we are only left to wonder—what kind of applications will it provide us with next?

But, first things first. In a round-table discussion with undergraduates, Lloyd speaks of his early days in the field with a touch of humor, irony, and most surprisingly—pride. When he just started to research quantum information in graduate school, most scientists told him to look into other areas. In fact, out of the postdoctoral programs he considered, not many were too invested in researching of information in quantum mechanics. Most universities and institutes were reluctant to take up quantum computing, but Murray Gell-Mann accepted Lloyd for a position at the California Institute of Technology. This is where many ideas behind quantum computation were born, and Lloyd is “excited by the popularity of the field today.”

Synopsis: Diamond Qubits Take the Stage

Posted by in categories: computing, particle physics, quantum physics

A ten-qubit system based on spins in impure diamond achieves coherence times of over a minute.

In the global race to build a quantum computer, it’s still unclear what material will make the best qubit. Companies have bet on a variety of architectures based on trapped ions, neutral atoms, superconducting circuits, and more. Now, Tim Taminiau of Delft University of Technology, Netherlands, and colleagues have demonstrated that they can manipulate magnetic spins inside diamond into the robust quantum states necessary for quantum computing. In their experiment, they entangle all possible pairs of a ten-qubit system and produce states in which seven different qubits are entangled simultaneously. They also show that individual qubits can retain quantum coherence for up to 75 s—a record for solid-state systems.
