Superconducting circuit links smaller photon groups into larger entangled states
Quantum computers, computer systems that leverage the laws of quantum mechanics, store and process information using qubits (i.e., quantum bits). In many quantum computers, qubits are linked via entanglement, a quantum mechanical ...
Lensless imaging method enables long-term monitoring of living cells without staining
In a study led by Tampere University, researchers have developed a new lensless imaging method that produces precise quantitative data on living cells from a single image. The compact system can be placed inside a standard ...

Levitating glass sphere becomes entangled with light at room temperature
Today, many physicists are actively exploring how light could be used to link objects through quantum entanglement. By fully harnessing the effect, they hope to unlock a wide array of applications, from secure communication ...
Cricket's day-night pink ball not always so pretty
The pink ball was introduced for day-night matches over a decade ago, and in June this year the International Cricket Council (ICC) approved a trial of pink balls in Tests expected to be affected by bad light—subject to prior ...

X-ray technique reveals how quantum materials respond to laser pulses in real time
Creating a quantum device often begins by intentionally damaging a crystal. Scientists fire an ultrafast laser pulse into a material, knocking atoms out of place and leaving behind tiny imperfections called vacancies. Far ...

Reading hidden topology in light, even when energy leaks away
When I explain topology to students, I start with a knot in a rope. You can stretch it, twist it or shake it, but the knot stays until you cut the rope. Physicists have found that some materials and devices carry similar ...
Visible light does not speed up water evaporation, rigorous experiments suggest
In recent experiments involving hydrogels and water droplets, researchers have proposed that exposure to visible light could make water evaporate faster without heating it. However, direct evidence that light acts on water ...
Protons ride moving waves to reach record energy with long-pulse lasers
Imagine a proton catching a wave and surfing it to gain speed. While the imagery may seem wild, the premise of laser-driven ion acceleration has promise as an alternative to conventional accelerators. However, the ultrathin ...
