This Math Problem Stumped Scientists for Almost a Century — Two Mathematicians Have Finally Solved It

Posted by in category: mathematics

We’ve all been there: staring at a math test with a problem that seems impossible to solve. What if finding the solution to a problem took almost a century? For mathematicians who dabble in Ramsey theory, this is very much the case. In fact, little progress had been made in solving Ramsey problems since the 1930s.

Now, University of California San Diego researchers Jacques Verstraete and Sam Mattheus have found the answer to r(4,t), a longstanding Ramsey problem that has perplexed the math world for decades.

Breaking the Limits: Overcoming Heisenberg’s Uncertainty in Quantum Measurements

Posted by in categories: computing, engineering, quantum physics

Aalto University researchers are the first in the world to measure qubits with ultrasensitive thermal detectors—thus evading the Heisenberg uncertainty principle.

Chasing ever-higher qubit counts in near-term quantum computers constantly demands new feats of engineering.

Among the troublesome hurdles of this scaling-up race is refining how qubits are measured. Devices called parametric amplifiers are traditionally used to do these measurements. But as the name suggests, the device amplifies weak signals picked up from the qubits to conduct the readout, which causes unwanted noise and can lead to decoherence of the qubits if not protected by additional large components. More importantly, the bulky size of the amplification chain becomes technically challenging to work around as qubit counts increase in size-limited refrigerators.

First fractal molecule in nature recently discovered by accident

Posted by in category: futurism

An international team of researchers has stumbled upon a remarkable discovery — the first regular molecular fractal in nature.

This fascinating finding, led by groups from the Max Planck Institute and the Philipps University in Marburg, Germany, has unveiled a microbial enzyme that spontaneously assembles into a pattern known as the Sierpinski triangle.

The enzyme, identified as citrate synthase from a cyanobacterium, was discovered by chance. “We stumbled on this structure completely by accident and almost couldn’t believe what we saw when we first took images of it using an electron microscope,” says Franziska Sendker, the study’s first author.

Light-Matter Particle Breakthrough Could Change Displays Forever

Posted by in categories: innovation, particle physics

POSTECH researchers have created a technique for controlling polaritons, which could lead to advancements in optical displays and various optoelectronic devices.

A research team consisting of Professor Kyoung-Duck Park and Hyeongwoo Lee, an integrated PhD student, from the Department of Physics at Pohang University of Science and Technology (POSTECH) has pioneered an innovative technique in ultra-high-resolution spectroscopy. Their breakthrough marks the world’s first instance of electrically controlling polaritons—hybridized light-matter particles—at room temperature.
