A new quantum communication method uses the temporal Talbot effect to simplify high-dimensional quantum key distribution.
Killing horizon: a thought experiment suggests that the presence of a black hole can decohere a quantum superposition. (Courtesy: Shutterstock/Rost9) A new thought experiment suggests that the mere ...
Scientists created quantum superposition states at temperatures up to 60 times hotter than their environment, challenging the assumption that quantum effects require extreme cold. This discovery could ...
