Unlocking the quantum code: International team cracks a long-standing physics problem

SciTechDaily

Researchers have developed a new method called wavefunction matching to tackle the sign problem in Monte Carlo simulations, a common issue in many-body quantum physics. By simplifying the interaction model and using perturbation theory for corrections, this method has proven effective in accurately calculating nuclear properties such as mass and radius. It holds promise for … Read more

Tunable coupling of two distant superconducting spin qubits

Tunable coupling of two distant superconducting spin qubits

The complete chip mounted on a printed circuit board. Credit: Pita-Vidal, Wesdorp et al. Quantum computers, computing devices that use the principles of quantum mechanics, can outperform classical computing in some complex optimization and processing tasks. In quantum computers, the classical units of information (bits), which can have the value 1 or 0, are replaced … Read more

Astrophysicists may have solved the mystery of disappearing stars

black hole and star

Instead of dying dramatically in a massive supernova explosion, some massive stars can die quietly and without fanfare. This could explain the mysterious and sudden disappearance of some stars from the night sky observed by astronomers over the years, according to a new journal article. Physical review papers. These massive stars can completely collapse in … Read more

First observation of a focused plasma wave in the Sun

First observation of a focused plasma wave in the Sun

Numerical simulation of the MHD lens process in t/t0=0.185 based on the observed geometric shape of CH. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-46846-z For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, similar to the focusing of sound waves responsible for the Rotunda effect in architecture … Read more

The ground-breaking measurement reveals a black hole rotating at a quarter of the speed of light

The ground-breaking measurement reveals a black hole rotating at a quarter of the speed of light

A team of astronomers has managed to calculate the speed of rotation of distant supermassive black holes thanks to the chance meeting of objects with a star, which it immediately destroyed. How “Time Travel” Will Change Perry in The Outer Range Season 2 All black holes have spin, which they develop through their interactions with … Read more
