DARPA Selects Northrop Grumman, Umbra for Phase II of DRIFT Program

Posted by in categories: information science, military, satellites

Northrop Grumman and Umbra have been awarded small contracts by the Defense Advanced Research Projects Agency (DARPA) to continue to the second phase of a program designed to collect data from radar-equipped satellites flying in formation and develop innovative algorithms to process the data for military applications.

Umbra’s contract under the Distributed Radar Image Foundation Technology (DRIFT) program is for $6 million and will last for six months and Northrop Grumman’s is for $2 million and covers one year, a DARPA spokesperson said.

Spinning Up Rydberg Atoms Extends Their Life

Posted by in category: particle physics

Researchers record the longest Rydberg-atom lifetime by placing strontium atoms in “circular” states, where the outer electrons move in planet-like orbits.

DARPA is testing this autonomous tank with glowing “eyes”

Posted by in categories: military, neuroscience, robotics/AI

DARPA just tested an autonomous tank that could help keep soldiers safe — and even more self-driving military vehicles are on the horizon. If autonomous vehicles prove capable enough for the battlefield, the tech could someday start finding its way over to civilian uses, too.

The challenge: Tanks have played an important role in the US military for more than 100 years, thanks to their tremendous firepower and armor, but every time the Army puts a soldier into a tank and sends them into combat, it’s putting their life at risk.

Near-flawless quantum teleportation demonstrated in groundbreaking experiment

Posted by in categories: particle physics, quantum physics

TURKU, Finland — Beam me up, Scotty! In a study that seems straight out of a “Star Trek” episode, an international team of researchers has achieved a remarkable feat in the realm of quantum teleportation. They have successfully conducted near-perfect quantum teleportation despite the presence of noise that typically disrupts the transfer of quantum states.

Quantum teleportation is a process in which the state of a quantum particle, or qubit, is transferred from one location to another without physically sending the particle itself. This transfer requires quantum resources, such as entanglement between an additional pair of qubits.

Imagine you have a secret message written on a piece of paper. You want to send this message to someone far away without anyone else seeing it. In quantum teleportation, instead of physically sending the paper, you would make an exact copy of the message at the other location while the original message gets destroyed. This requires some special resources like entanglement, which is like a mysterious connection between two qubits.

Why is it ok for people to be saying that dark matter makes up x amount of the universe when we don’t know what it is?

Posted by in category: cosmology

It strikes me as contradictory that the scientific community will say that we don’t know what dark matter is, but be happy to state things like “dark matter makes up about 85% of the cosmos” (source: phys.org)

Is there something wrong with the way I’m thinking about this? If MOND is correct for example, which seems to be a possibility still, wouldn’t this mean that the statement about dark matter making up a certain percentage of the universe be false?
