A Peculiar Protected Structure Links Viking Knots With Quantum Vortices A vortex structure that is impervious to decay has been identified through mathematical analysis. In…
Physicists observe wormhole dynamics using a quantum computer in a step toward studying quantum gravity in the lab. For the first time, scientists have developed…
For the first time, physicists have experimentally demonstrated that there is a negative correlation between the two spins of an entangled pair of electrons from…
Bizarre quantum properties of black holes – including their mind-bending ability to have different masses simultaneously – have been confirmed by University of Queensland (UQ)…
In nature, vortices can be found everywhere: Whirling up water can produce swirls. When the atmosphere is stirred up, huge tornadoes can form. This is…
Scientists believe our brains could use quantum computation after taking a concept developed to prove the existence of quantum gravity and adapting it to explore…
A new method for simulating quantum entanglement between interacting particles has been developed by physicists. Physicists are (temporarily) augmenting reality in order to crack the…
