Quantum squeezing is a concept in quantum physics where the uncertainty in one aspect of a system is reduced while the uncertainty in another related aspect is increased. Imagine squeezing a round balloon filled with air. In its normal state, the balloon is perfectly spherical. When you squeeze one side, it gets flattened and stretched out in the other direction. This represents what is happening in a squeezed quantum state: you are reducing the uncertainty (or noise) in one quantity, like position, but in doing so, you increase the uncertainty in another quantity, like momentum. However, the total uncertainty remains the same, since you are just redistributing it between the two. Even though the overall uncertainty remains the same, this ‘squeezing’ allows you to measure one of those variables with much greater precision than before.

This technique has already been used to improve the accuracy of measurements in situations where only one variable needs to be precisely measured, such as in improving the precision of atomic clocks. However, using squeezing in cases where multiple factors need to be measured simultaneously, such as an object’s position and momentum, is much more challenging.

In a research paper published in Physical Review Research (“Squeezing-induced quantum-enhanced multiphase estimation”), Tohoku University’s Dr. Le Bin Ho explores the effectiveness of the squeezing technique in enhancing the precision of measurements in quantum systems with multiple factors. The analysis provides theoretical and numerical insights, aiding in the identification of mechanisms for achieving maximum precision in these intricate measurements.

Altman predicts that with AI in the future, “We will be able to do things that would have seemed like magic to our grandparents.”

Power outages continued for many in the Eastern U.S. early on Monday as Helene’s death toll passed 100.

The company said its technology can recover 300% more lithium than conventional methods. Traditional extraction typically yields 30% to 40% of lithium from brine, while EnergyX said its DLE achieves a +90% extraction rate.

The technology has raised over $110 million in total funding, backed by investors including General Motors, Eni and POSCO.

With two Tier 1 projects underway, Black Giant in Chile is estimated to produce 40,000 tonnes of lithium per year, while Project Lonestar in the US is estimated at 25,000 tonnes.

The world’s second-largest money transfer provider, which filed a data breach notice with U.K. authorities, serves over 50 million people.

AIs have a big problem with truth and correctness – and human thinking appears to be a big part of that problem. A new generation of AI is now starting to take a much more experimental approach that could catapult machine learning way past humans.

Remember Deepmind’s AlphaGo? It represented a fundamental breakthrough in AI development, because it was one of the first game-playing AIs that took no human instruction and read no rules.
