Artemis 2 Orion spacecraft starts testing ahead of moon mission with astronauts in 2025 (video)

Posted by in category: space travel

NASA’s next moon spacecraft for humans made one small leap into an altitude chamber for vital testing before it brings astronauts on board.

The Orion spacecraft for Artemis 2 is slated to fly around the moon with four astronauts no earlier than September 2025 — but first, engineers with NASA want to make sure it is ready for the job.

Physicists solve puzzle about ancient galaxy found by Webb telescope

Posted by in categories: physics, space

Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That’s because JWST-ER1g acts as a lens and bends light from a distant source, which then appears as a ring—a phenomenon called strong gravitational lensing, predicted in Einstein’s theory of general relativity.

Elon Musk ‘guesses’ AI will be brighter than people by the end of 2026, but there’s a 20% chance it might end humanity anyway

Posted by in categories: Elon Musk, robotics/AI

Generative AI is quite impressive and has been the common denominator (in most cases) when tapping into new opportunities and unlocking new heights in the tech landscape. Microsoft has significantly benefited from the technology and is currently ranking as the world’s most valuable company, ahead of Apple with over $3 trillion in market capitalization. Market analysts attribute part of this success to its early investment and adoption of AI across its products and services.

Still, AI encounters its fair share of setbacks coupled with controversies and rumors. Perhaps one of the main challenges facing the technology is the lack of elaborate measures and guardrails to prevent it from spiraling out of control.

While relevant parties continue to try to establish control over the technology, billionaire Elon Musk predicts AI will be more intelligent than humans by the end of 2026 (via Business Insider). Musk shared these sentiments in an interview with Norges Bank CEO Nicolai Tangen on X (formerly Twitter).

Photonic Quantum Computing: A Promising Future With Mature Technologies And Room-Temperature Operations

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

Photonic quantum computation, a type of quantum computation that uses light particles or photons, is divided into two main categories: discrete-variable (DV) and continuous-variable (CV) photonic quantum computation. Both have been realized experimentally and can be combined to overcome individual limitations. Photonic quantum computation is important as it can perform specific computational tasks more efficiently. It has several advantages, including the ability to observe and engineer quantum phenomena at room temperature, maintain coherence, and be engineered using mature technologies. The future of photonic quantum computing looks promising due to the significant progress in photonic technology.

Photonic quantum computation is a type of quantum computation that uses photons, particles of light, as the physical system for performing the computation. Photons are ideal for quantum systems because they operate at room temperature and photonic technologies are relatively mature. The field of photonic quantum computation is divided into two main categories: discrete-variable (DV) and continuous-variable (CV) photonic quantum computation.

In DV photonic quantum computation, quantum information is represented by one or more modal properties, such as polarization, that take on distinct values from a finite set. Quantum information is processed via operations on these modal properties and eventually measured using single photon detectors. On the other hand, in CV photonic quantum computation, quantum information is represented by properties of the electromagnetic field that take on any value in an interval, such as position. The electromagnetic field is transformed via Gaussian and non-Gaussian operations and then detected via homodyne detection.

Peter Higgs transformed what we know about the building blocks of the universe

Posted by in category: particle physics

Peter Higgs, who gave his name to the subatomic particle known as the Higgs boson, has died aged 94. He was always a modest man, especially when considering that he was one of the greats of particle physics—the area of science concerned with the building blocks of matter.

Exploring Quantum Teleportation: Qubit Transfer With Exotic Entangled States

Posted by in categories: particle physics, quantum physics

Quantum teleportation is a process by which quantum information can be transmitted from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location. This process is not to be confused with teleportation as depicted in science fiction, where matter is instantaneously transported from one location to another. Instead, quantum teleportation involves the transfer of quantum states between particles at different locations without any physical movement of the particles themselves.

In a recent study by Isiaka Aremua and Laure Gouba, the researchers explored the teleportation of a qubit using exotic entangled coherent states. A qubit, or quantum bit, is the basic unit of quantum information. It is a quantum system that can exist in any superposition of its two basis states. The researchers used a system of an electron moving on a plane in uniform external magnetic and electric fields to construct different classes of coherent states.

Coherent states are specific states of a quantum harmonic oscillator. They are often described as the quantum equivalent of classical states because they closely resemble the behavior of classical particles. In the context of quantum teleportation, coherent states are used to form entangled states, which are crucial for the teleportation process.

Mysterious star that ‘woke up’ is sending strange radio signals across Milky Way leaving scientists baffled

Posted by in category: cosmology

MYSTERIOUS signals are being detected coming from a star that has been radio silent for over a decade, according to scientists.

The radio signals are very powerful and their sudden appearance has baffled experts.

According to Live Science, the strange star is a magnetar that suddenly became very active again in 2018.
