New ‘light-structure’ technique could solve some of quantum computing’s biggest challenges

“I find it totally amazing that it is possible at all to build these light structures.”

A Ph.D. candidate at has developed an innovative technique for creating the elementary building blocks of a future quantum computer or internet in a more controlled manner, opening up a potential solution to many of the challenges along the road to this long-sought technology.

Petr Steindl’s doctoral thesis, which he defended last week as the final step in his Ph.D. program at Leiden University in Germany, explores a new technique for generating photons using quantum dots and microcavities.

Impossible Quantum Drive That Defies Known Laws of Physics Scheduled for “Do or Die” October Space Flight

A controversial new type of electric propulsion system that physicists say defies Newton’s Laws of Motion, known as the Quantum Drive, has secured a spot on a SpaceX rocket and will launch into low Earth orbit (LEO) this October.

Designed by IVO Ltd., an electronics prototyping company, the promising yet controversial Quantum Drive could change the future of space travel and, if proven to work, would potentially rewrite or expand many of the accepted principles of inertia and motion that have existed for centuries.

Newtonian Physics Says creating inertia Without Propellant is Impossible.

Quantum Physics in a Leaf? Scientists Discover Link Between Photosynthesis and the “Fifth State of Matter”

Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Meanwhile, just outside their window, trees are absorbing sunlight and converting it into new leaves. These two scenarios may seem entirely unrelated, but a recent study from the University of Chicago proposes that these processes are not as distinct as they might appear on the surface.

Published in the journal PRX Energy, the study established connections at the atomic level between the process of photosynthesis and exciton condensates, —a strange state of physics that allows energy to flow frictionlessly through a material. According to the authors, this discovery is not only fascinating from a scientific perspective, but it may also offer new perspectives for electronics design.

AI, quantum and nuclear technologies are key to Lockheed Martin’s vision for Space 2050

LOS ANGELES – Artificial intelligence, quantum computing and nuclear power are among the key technologies Lockheed Martin sees as important for future space missions.

Through a project called Destination: Space 2050, Lockheed Martin executives are exploring, for example, how AI could assist scientific exploration of locations where communications with remote sensors would be disrupted by high latency.

In that type of environment, “you really can’t interact with the robotic sensors,” David Lackner, Lockheed Martin senior manager strategy and business development, said during a June 28 webinar. “You have to have something that is super autonomous that can deal with unknown unknowns. We’ve got some really interesting causal autonomy tools that … allow the AI to be super smart about running into something that it hasn’t encountered before.”

How quantum dots can revolutionize solar energy

There’s a new way to harness the power of the sun and it may just revolutionize how we approach solar energy. The development is called quantum dots and it consists of tiny semiconductor particles only a few nanometers in size.

This is according to a report by Fagen Wasanni published on Saturday.

“Quantum dots have unique properties that make them ideal for use in solar cells. Their small size allows them to absorb light from a wide range of wavelengths, including those that traditional solar cells cannot capture. This means that quantum dot-based solar cells can potentially convert more sunlight into electricity, significantly increasing their efficiency,” states the report.

Fluxonium Qubit Retains Information For 1.43 Milliseconds — 10x Longer Than Before

Superconducting quantum technology has long promised to bridge the divide between existing electronic devices and the delicate quantum landscape beyond. Unfortunately progress in making critical processes stable has stagnated over the past decade.

Now a significant step forward has finally been realized, with researchers from the University of Maryland making superconducting qubits that last 10 times longer than before.

What makes qubits so useful in computing is the fact their quantum properties entangle in ways that are mathematically handy for making short work of certain complex algorithms, taking moments to solve select problems that would take other technology decades or more.

European researchers design a rubber block that can count to ten

Physicist Lennard Kwakernaak finds the “complexity of simple things” intriguing, and it is a tough ask to make an inanimate object count.

A collaboration between researchers at Leiden University and AMOLF in Amsterdam has yielded a new metamaterial, a rubber block that can count. The researchers are calling it a Beam Counter and it is pretty nifty.

In a world where researchers are racing to make a quantum computer that can do complex math, building a new rubber block might not seem like much. But physicist Lennard Kwakernaak finds the “complexity of simple things” intriguing, and it is a tough ask to make an inanimate object count.
