Could human civilization spread across the whole galaxy?

Posted by in categories: media & arts, space

Could human civilization eventually spread across the whole Milky Way galaxy? Could we move beyond our small, blue planet to establish colonies in the multitude of star systems out there? These questions are pretty daunting, but their (theoretical) answers were actually put forth decades ago. Roey Tzezana describes the conceptual von Neumann machine.

Hawking’s black hole paradox explained

Posted by in categories: cosmology, media & arts, particle physics, quantum physics

Today, one of the biggest paradoxes in the universe threatens to unravel modern science: the black hole information paradox. Every object in the universe is composed of particles with unique quantum properties and even if an object is destroyed, its quantum information is never permanently deleted. But what happens to that information when an object enters a black hole? Fabio Pacucci investigates.

Scientists discover they can pull water molecules apart using graphene electrodes

Posted by in categories: economics, energy, physics

Writing in Nature Communications, a team led by Dr. Marcelo Lozada-Hidalgo based at the National Graphene Institute (NGI) used graphene as an electrode to measure both the electrical force applied on water molecules and the rate at which these break in response to such force. The researchers found that water breaks exponentially faster in response to stronger electrical forces.

The researchers believe that this fundamental understanding of interfacial water could be used to design better catalysts to generate from water. This is an important part of the U.K.’s strategy towards achieving a net zero economy. Dr. Marcelo Lozada-Hidalgo said, “We hope that the insights from this work will be of use to various communities, including physics, catalysis, and interfacial science and that it can help design better catalysts for green hydrogen production.”

A water molecule consists of a proton and a hydroxide ion. Dissociating it involves pulling these two constituent ions apart with an electrical force. In principle, the stronger one pulls the water molecule apart, the faster it should break. This important point has not been demonstrated quantitatively in experiments.

A new method to enable efficient interactions between photons

Posted by in categories: particle physics, quantum physics

Photons, particles that represent a quantum of light, have shown great potential for the development of new quantum technologies. More specifically, physicists have been exploring the possibility of creating photonic qubits (quantum units of information) that can be transmitted over long distances using photons.

Despite some promising results, several obstacles still need to be overcome before photonic qubits can be successfully implemented on a large-scale. For instance, are known to be susceptible to propagation loss (i.e., a loss of energy, radiation, or signals as it travels from one point to another) and do not interact with one another.

Researchers at University of Copenhagen in Denmark, Instituto de Física Fundamental IFF-CSIC in Spain, and Ruhr-Universität Bochum in Germany have recently devised a strategy that could help to overcome one of these challenges, namely the lack of photon-photon interactions. Their method, presented in a paper published in Nature Physics, could eventually aid the development of more sophisticated quantum devices.

Musk: Tesla Semi truck coming in December, first deliveries to Pepsi

Posted by in categories: Elon Musk, sustainability, transportation

As if Elon Musk’s week couldn’t be more eventful, the Tesla (TSLA) CEO gave the automotive world more news to chew on.

In a tweet last night, Musk said Tesla has begun production of its long-awaited electric Tesla Semi truck, and that deliveries to Pepsi (PEP) would begin on December 1st. In a follow-up tweet, Musk said the semi would have 500 miles of range and would be “super fun to drive.”

Intel hits major milestone as it moves toward mass production of quantum computer chips

Posted by in categories: computing, quantum physics

Intel Corp.’s two primary research organizations, Intel Labs and Components Research, announced today that they’re making big progress as they work toward large-scale production of quantum computing processors.

At the 2022 Silicon Quantum Electronics Workshop in Orford, Quebec, Intel’s researchers said that they’ve been able to demonstrate the highest reported yield and uniformity rate when manufacturing “silicon spin qubit devices” at the company’s transistor research and development facility. The research is believed to be a key milestone for Intel as it moves toward being able to fabricate quantum computing chips on its existing transistor manufacturing processes.

Intel is a key player in the race to build quantum computers, which are more advanced machines that encode data as “qubits,” as opposed to the conventional bits used in traditional computers. The advantage of qubits is they’re not restricted to states of 1 or 0. They can also exist as both states at the same time, a characteristic that’s known as superposition.
