Quantum Computing: Why is it Better Than Supercomputers?

Posted by in categories: biotech/medical, quantum physics, robotics/AI, supercomputing

Researchers in the US developed a new energy-based benchmark for quantum advantage and used it to demonstrate noisy intermediate-scale quantum (NISQ) computers that use several orders of magnitude less energy than the world’s most powerful supercomputer. Quantum computing is a branch of computer science that focuses on the development of technologies based on quantum theory principles.

Quantum computing solves problems that are too complex for classical computing by utilizing the unique properties of quantum physics. The question of whether a quantum computer can perform calculations beyond the reach of even the most powerful conventional supercomputer is becoming increasingly relevant as quantum computers become larger and more reliable. This ability, dubbed “quantum supremacy,” marks the transition of quantum computers from scientific curiosity to useful devices. Scientists predict that Quantum computing is better than supercomputers as it performs tasks a million times faster. Quantum computers can handle complex calculations easily because they are built based on quantum principles that go beyond classical physics.

Quantum computers and supercomputers are extremely powerful machines used for complex calculations, problem solving, and data analysis. While both have the potential to revolutionize computing technology, they have significant speed and capability differences. In 2019, Google’s quantum computer performed a calculation that would take the world’s most powerful computer 10,000 years to complete. It is the seed for the world’s first fully functional quantum computer, which will be capable of producing better medicines, developing smarter artificial intelligence, and solving cosmic mysteries. Theoretical physicist John Preskill proposed a formulation of quantum supremacy, or the superiority of quantum computers, in 2012. He dubbed it the moment when quantum computers can perform tasks that ordinary computers cannot. To quickly crunch large amounts of data and achieve a single result, supercomputers employ a traditional computing approach with multiple processors.

Theorizing the Basis of Our World: A Reading List on Quantum Reality

Posted by in categories: mobile phones, nuclear energy, particle physics, quantum physics

Quantum Mechanics is the science behind nuclear energy, smart phones, and particle collisions. Yet, almost a century after its discovery, there is still controversy over what the theory actually means. The problem is that its key element, the quantum-mechanical wave function describing atoms and subatomic particles, isn’t observable. As physics is an experimental science, physicists continue to argue over whether the wave function can be taken as real, or whether it is just a tool to make predictions about what can be measured—typically large, “classical” everyday objects.

The view of the antirealists, advocated by Niels Bohr, Werner Heisenberg, and an overwhelming majority of physicists, has become the orthodox mainstream interpretation. For Bohr especially, reality was like a movie shown without a film or projector creating it: “There is no quantum world,” Bohr reportedly affirmed, suggesting an imaginary border between the realms of microscopic, “unreal” quantum physics and “real,” macroscopic objects—a boundary that has received serious blows by experiments ever since. Albert Einstein was a fierce critic of this airy philosophy, although he didn’t come up with an alternative theory himself.

For many years only a small number of outcasts, including Erwin Schrödinger and Hugh Everett populated the camp of the realists. This renegade view, however, is getting increasingly popular—and of course triggers the question of what this quantum reality really is. This is a question that has occupied me for many years, until I arrived at the conclusion that quantum reality, deep down at the most fundamental level, is an all-encompassing, unified whole: “The One.”

Extremely Dense Atom-sized Primordial Black Holes Could Weigh Millions of Tons, Experts RAtom-sized Primordial Black Holes Are Extremely Dense Objects That Could Weigh Millions of Tons, Experts Reveal

Posted by in categories: cosmology, particle physics

One of Albert Einstein’s theory of general relativity’s most fascinating predictions is the possibility of black holes, which are created after a massive star reaches the end of its life and collapses. Supermassive black holes as big as 100,000 or ten billion times the Sun are commonly found at the center of most galaxies.

Those are the biggest form of black holes, but it is also thought that primordial black holes (PBHs) also exist. Unlike the big ones, these tiny black holes emerged in the early cosmos through the gravitational collapse of extraordinarily dense areas.

Some Meta employees are getting paid to do ‘zero work’ as the company embarks on a ‘year of efficiency’: Financial Times

Posted by in category: futurism

The tech giant — which laid off 11,000 people in November and promised that 2023 is to be a “year of efficiency” — is gearing up for a new round of layoffs that might be wreaking havoc with some of the teams’ productivity, the Financial Times reported on Saturday, citing two employees familiar with the situation.

There’s been a lack of clarity about some budgets — which would typically get finalized by the end of the year — and future head count in recent weeks. Hence, projects and decisions that typically take days to sign off are taking up to a month, the Meta staffers told the FT.

That has caused some staff to do “zero work” because managers have not been able to plan their schedules.

Study Reveals How CBD Counters Epileptic Seizures

Posted by in category: neuroscience

Summary: Cannabidiol, or CBD, blocks the ability of lysophosphatidylinositol (LPI) to amplify neural signals in the hippocampus. LPI weakens the signals that counter seizures, further explaining the value of CBD to treat epilepsy.

A study reveals a previously unknown way in which cannabidiol (CBD), a substance found in cannabis, reduces seizures in many treatment-resistant forms of pediatric epilepsy.

EHT Peers Into The Heart of One of The Brightest Lights in The Universe

Posted by in categories: cosmology, physics

The global collaboration that delivered us not one but two pictures of supermassive black holes has now peered into one of the brightest lights in the Universe.

The Event Horizon Telescope (EHT), a telescope array comprising radio antennae around the world, studied a distant quasar named NRAO 530, whose light has traveled for 7.5 billion years to reach us.

The resulting data show us the quasar’s engine in incredible detail and will, astronomers say, help us understand the complex physics of these incredible objects, and how they generate such blazing light.

New Models Help Unveil the Mystery of Life’s Origins on Earth

Posted by in categories: biological, chemistry

New research reveals clues about the physical and chemical characteristics of Earth when life is thought to have emerged.

About four billion years ago, the first signs of life emerged on Earth in the form of microbes. Although scientists are still determining exactly when and how these microbes appeared, it’s clear that the emergence of life is intricately intertwined with the chemical and physical characteristics of early Earth.

“It is reasonable to suspect that life could have started differently—or not at all—if the early chemical characteristics of our planet were different,” says Dustin Trail, an associate professor of earth and environmental sciences at the University of Rochester.
