Hot Schrödinger cat states created
In Erwin Schrödinger’s thought experiment, it is a cat that is alive and dead at the same time. Credit: University of Innsbruck/Harald Ritsch Quantum states can only be prepared and…
Physicists uncover electronic interactions mediated via spin waves
Rendition of the discovery where the excitons (e–h pairs) interact via ripples in the magnetic structure akin to an array of spinning tops generating a wave that affects each other…
Microwave pulses can control ion-molecule reactions at near absolute zero
Credit: Physical Review Letters (2025). DOI: 10.1103/PhysRevLett.134.123401 To demonstrate their proposed approach, the researchers first cooled molecules down to their rotational ground state. In this state, the molecules are known…
Scientists unveil new way to electrically control spin for ultra-compact devices using altermagnetic quantum materials
Electrical current flowing in an altermagnetic bilayer CrS can become spin-polarized using an external electric field, thus paving a way towards all-electrical spintronic devices for future computing technology. Credit: SUTD…
Hidden side channels in quantum sources could compromise secure communication
University of Toronto Engineering Ph.D. student Amita Gnanapandithan used both practical experiments and computer modeling to demonstrate the existence of “hidden” side channels in devices that produce photons used in…
A quantum superhighway for ultrafast NOON states
A NOON state is a superposed quantum state where N particles are in one state “at the same time” and in another “at the same time.” Here, the particles are…
