For that, they will need the quantum equivalent of optical repeaters, the components of today’s telecommunications networks that keep light signals strong across thousands of kilometers of optical fiber. Several teams have already demonstrated key elements of quantum repeaters and say they’re well on their way to building extended networks. “We’ve solved all the scientific problems,” says Mikhail Lukin, a physicist at Harvard University. “I’m extremely optimistic that on the scale of 5 to 10 years… we’ll have continental-scale network prototypes.”
Advance could precisely link telescopes, yield hypersecure banking and elections, and make quantum computing possible from anywhere.
Microsoft keeps hinting at a new version of Windows.
Microsoft has been teasing a “next generation” of Windows for months now, but new hints suggest the company isn’t just preparing an update to its existing Windows 10 software, but a new, numbered version of the operating system: Windows 11.
The software giant announced a new Windows event for June 24th yesterday, promising to show “what’s next for Windows.” The event invite included an image of what looks like a new Windows logo, with light shining through the window in only two vertical bars, creating an outline that looks very much like the number 11. Microsoft followed up with an animated version of this image, making it clear the company intentionally ignored the horizontal bars.
In a recent interview, Elon Musk stated that the human language could possibly end within five to ten years. The CEO of Neuralink went to talk with Joe Rogan, implying that with the innovation of the brain chip the company is currently developing, humans won’t have to speak anymore using traditional languages.
Neuralink develops a chip that will soon be able to attach to the human brain. The chip’s invention aimed to communicate faster and conveniently. Through a single universal language, Elon Musk believes that the way we talk today will soon improve. The brain chip is expected to be completed to be developed within a few years, and by then, our communication could possibly evolve.
Elon Musk stated that the Neuralink chip’s success may take a while, but it should take five to ten years if the development will accelerate. He also added that the progress of the brain chip is on track, but with only to focus on their current objective, which is to help people minimize and prevent brain injuries, Express reported.
Elon Musk’s Brain Chip Completion on Progress, Initial Batch Will Solve Brain Injuries
The brain chip’s power was already displayed in a 2019 long-stream video by Neuralink. In the video published on the YouTube channel Monkey MindPong, a monkey with an active chip on its brain was shown playing a video game that is similar to a table tennis match. The astounding display of the monkey’s brain reaction toward the game left experts in awe.
La Intel Xe-HPG cada vez es más real y después de varios rumores se han podido ver las primeras imágenes de esta GPU gaming.
In January 2020 we released the fly “hemibrain” connectome — an online database providing the morphological structure and synaptic connectivity of roughly half of the brain of a fruit fly (Drosophila melanogaster). This database and its supporting visualization has reframed the way that neural circuits are studied and understood in the fly brain. While the fruit fly brain is small enough to attain a relatively complete map using modern mapping techniques, the insights gained are, at best, only partially informative to understanding the most interesting object in neuroscience — the human brain.
Today, in collaboration with the Lichtman Laboratory at Harvard University, we are releasing the “H01” dataset, a 1.4 petabyte rendering of a small sample of human brain tissue, along with a companion paper, “A connectomic study of a petascale fragment of human cerebral cortex.” The H01 sample was imaged at 4nm-resolution by serial section electron microscopy, reconstructed and annotated by automated computational techniques, and analyzed for preliminary insights into the structure of the human cortex. The dataset comprises imaging data that covers roughly one cubic millimeter of brain tissue, and includes tens of thousands of reconstructed neurons, millions of neuron fragments, 130 million annotated synapses, 104 proofread cells, and many additional subcellular annotations and structures — all easily accessible with the Neuroglancer browser interface.
Physicists at the University of Bath in the UK, in collaboration with researchers from the USA, have uncovered a new mechanism for enabling magnetism and superconductivity to co-exist in the same material. Until now, scientists could only guess how this unusual coexistence might be possible. The discovery could lead to applications in green energy technologies and in the development of superconducting devices, such as next-generation computer hardware.
As a rule, superconductivity (the ability of a material to pass an electrical current with perfect efficiency) and magnetism (seen at work in fridge magnets) make poor bedfellows because the alignment of the tiny electronic magnetic particles in ferromagnets generally leads to the destruction of the electron pairs responsible for superconductivity. Despite this, the Bath researchers have found that the iron-based superconductor RbEuFe4As4, which is superconducting below-236°C, exhibits both superconductivity and magnetism below-258°C.
Physics postgraduate research student David Collomb, who led the research, explained: There’s a state in some materials where, if you get them really cold—significantly colder than the Antarctic—they become superconducting. But for this superconductivity to be taken to next-level applications, the material needs to show co-existence with magnetic properties. This would allow us to develop devices operating on a magnetic principle, such as magnetic memory and computation using magnetic materials, to also enjoy the benefits of superconductivity.
Batteries and fuel cells often rely on a process known as ion diffusion to function. In ion diffusion, ionized atoms move through solid materials, similar to the process of water being absorbed by rice when cooked. Just like cooking rice, ion diffusion is incredibly temperature-dependent and requires high temperatures to happen fast.
This temperature dependence can be limiting, as the materials used in some systems like fuel cells need to withstand high temperatures sometimes in excess of 1000 degrees Celsius. In a new study, a team of researchers at MIT and the University of Muenster in Germany showed a new effect, where ion diffusion is enhanced while the material remains cold, by only exciting a select number of vibrations known as phonons. This new approach—which the team refers to as “phonon catalysis”—could lead to an entirely new field of research. Their work was published in Cell Reports Physical Science.
In the study, the research team used a computational model to determine which vibrations actually caused ions to move during ion diffusion. Rather than increasing the temperature of the entire material, they increased the temperature of just those specific vibrations in a process they refer to as targeted phonon excitation.
JÜLICH, Germany, May 28, 2021 — Quantum systems are considered extremely fragile. Even the smallest interactions with the environment can result in the loss of sensitive quantum effects. In the renowned journal Science, however, researchers from TU Delft, RWTH Aachen University and Forschungszentrum Jülich now present an experiment in which a quantum system consisting of two coupled atoms behaves surprisingly stable under electron bombardment. The experiment provide an indication that special quantum states might be realised in a quantum computer more easily than previously thought.
The so-called decoherence is one of the greatest enemies of the quantum physicist. Experts understand by this the decay of quantum states. This inevitably occurs when the system interacts with its environment. In the macroscopic world, this exchange is unavoidable, which is why quantum effects rarely occur in daily life. The quantum systems used in research, such as individual atoms, electrons or photons, are better shielded, but are fundamentally similarly sensitive.
“Systems subject to quantum physics, unlike classical objects, are not sharply defined in all their properties. Instead, they can occupy several states at once. This is called superposition,” Markus Ternes explains. “A famous example is Schrödinger’s thought experiment with the cat, which is temporarily dead and alive at the same time. However, the superposition breaks down as soon as the system is disturbed or measured. What is left then is only a single state, which is the measured value,” says the quantum physicist from Forschungszentrum Jülich and RWTH Aachen University.
Harvard University researchers have made a breakthrough in battery tech: a long-lasting solid-state lithium battery.
“A lithium-metal battery is considered the holy grail for battery chemistry,” researcher Xin Li told the Harvard Gazette.
Strong, cheaper, faster: Most of today’s electric vehicles (EVs) are powered by lithium-ion batteries, the same type of battery you’ll find in your laptop or smartphone.
