Next-level pixel-particle analogy uses quantum-inspired math to clarify noisy medical images
A medical image denoising method based on principles of quantum mechanics outperform machine learning, statistical methods, and neural networks. The same approach could aid quantum computing performance at scale. Credit:…
Quantum dot technique improves multi-photon state generation
The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring any active…
Quantum technologies—’Standards currently offer a greater chance of success than regulation,’ says researcher

Physicists capture elusive instability and exotic vortices
The swirling patterns in Vincent van Gogh’s “The Starry Night” can help us visualize quantum Kelvin-Helmholtz instability (KHI). The central spiral and surrounding stars and moon resemble the vortices formed…
Direct visualization of quantum zero-point motion in complex molecule reveals eternal dance of atoms
Ultrashort, high-intensity X-ray laser pulses trigger controlled explosions of molecules—making it possible to capture high-resolution images of molecular structures. Credit: Till Jahnke / Goethe University Frankfurt Most of us find…
Scientists achieve direct measurement of quantum metric tensor in black phosphorus
Researchers have successfully measured the quantum metric tensor in solids for the first time. Credit: Keun Su Kim from Yonsei University Quantum distance refers to a measure of quantum mechanical…
Researchers discover universal rules of quantum entanglement across all dimensions
Quantum entanglement in 1+1 and 2+1 dimensions. Credit: Yuya Kusuki A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions.…
New work achieves a pure quantum state without the need for cooling
Credit: CC0 Public Domain Three nano-glass spheres cling to one another. They form a tower-like cluster, similar to when you pile three scoops of ice cream on top of one…
Discovery of Planckian time limit opens doors to novel quantum technologies
