Making a Traversable Wormhole with a Quantum Computer

Posted by in categories: computing, cosmology, quantum physics

Wormholes — wrinkles in the fabric of spacetime that connect two disparate locations — may seem like the stuff of science fiction. But whether or not they exist in reality, studying these hypothetical objects could be the key to making concrete the tantalizing link between information and matter that has bedeviled physicists for decades.

Surprisingly, a quantum computer is an ideal platform to investigate this connection. The trick is to use a correspondence called AdS/CFT, which establishes an equivalence between a theory that describes gravity and spacetime (and wormholes) in a fictional world with a special geometry (AdS) to a quantum theory that does not contain gravity at all (CFT).

In “Traversable wormhole dynamics on a quantum processor”, published in Nature today, we report on a collaboration with researchers at Caltech, Harvard, MIT, and Fermilab to simulate the CFT on the Google Sycamore processor. By studying this quantum theory on the processor, we are able to leverage the AdS/CFT correspondence to probe the dynamics of a quantum system equivalent to a wormhole in a model of gravity. The Google Sycamore processor is among the first to have the fidelity needed to carry out this experiment.

This ‘Shark Tank’ Startup Is Making Vegan Bacon Out of Seaweed

Posted by in category: food

More people are opting to go vegetarian or vegan as factory farming’s impact on the planet becomes more apparent. But one carnivorous delight they may not have to give up is bacon, especially if they’re willing to be a bit flexible. A Dutch startup has been working on cultured bacon for a few years now, and New York-based MyForest Foods is producing a bacon substitute made from mushroom roots. They’ll soon have a competitor that will tempt consumers’ palates with yet another variety, this one made from a most unexpected source: seaweed (though to be fair, mushroom root is a pretty unexpected source for imitation bacon too).

Seaweed is good for you; it contains iodine as well as critical nutrients and antioxidants. But it doesn’t have the greatest taste (though this is admittedly a matter of personal preference; plenty of people love to snack on roasted sheets of the stuff). Umaro Foods, based in Berkeley, California, think they’ve found the perfect combination of ingredients to make seaweed taste—and feel—like bacon.

Engineers use quantum computing to develop transparent window coating that blocks heat, saves energy

Posted by in categories: climatology, computing, quantum physics

Cooling accounts for about 15 percent of global energy consumption. Conventional clear windows allow the sun to heat up interior spaces, which energy-guzzling air-conditioners must then cool down. But what if a window could help cool the room, use no energy and preserve the view?

Tengfei Luo, the Dorini Family Professor of Energy Studies at the University of Notre Dame, and postdoctoral associate Seongmin Kim have devised a transparent coating for windows that does just that.

The coating, or transparent radiative cooler (TRC), allows to come in and keeps other heat-producing light out. The researchers estimate that this invention can reduce electric cooling costs by one-third in hot climates compared to conventional glass windows.

Black hole simulated in lab began glowing

Posted by in categories: cosmology, physics

Physicists have simulated a black hole in a lab. Then it started glowing.

This allowed the team to realise that their black hole analogue may help explain so-called “Hawking radiation”, theorised to be emitted by black holes in nature.

Their analysis of the black hole in a bottle is presented in a paper published in the Physical Review Research journal.

Amazon debuts a fully autonomous warehouse robot

Posted by in categories: biotech/medical, employment, robotics/AI, space

You can’t discuss fulfillment robots without mentioning Amazon. Over the past decade, the retail juggernaut has become the 800-pound gorilla in the category, courtesy of several key acquisitions and seemingly endless resources. And while warehouse robotics and automation have been accelerated amid the pandemic and resulting employment crunch, Amazon Robotics has been driving these categories for years now.

This week at its annual Re: Mars conference in Las Vegas, the company celebrated a decade of its robotics division, which was effectively born with its acquisition of Kiva Systems. Over the course of its life, Amazon Robotics has deployed more than 520,000 robotic drive units, across its fulfillment and sort centers. From the outside, it’s been a tremendous success in the company’s push toward same-and next-day package delivery, and its driven the competition to look for their own third-party robotics solutions, bolstering startups like Locus, Fetch and Berkshire Grey.

Silent Synapses Are Abundant in the Adult Brain

Posted by in category: neuroscience

Summary: The adult brain contains millions of “silent synapses”, or immature connections between neurons that remain inactive until they are required for learning new information and storing new memories.

MIT neuroscientists have discovered that the adult brain contains millions of “silent synapses” — immature connections between neurons that remain inactive until they’re recruited to help form new memories.
