In Hilbert space, all things are quantumly possible

Physicists have demonstrated a way to encode and decode information in Hilbert space, a mathematical framework that underlies quantum mechanics. They used a device called a quantum processor to map classical information onto quantum states, allowing them to represent any possible configuration of a system in a single quantum state. This achievement has implications for quantum computing and quantum simulation, as it enables the representation of complex systems in a compact and efficient way. The research was led by researchers at the University of Innsbruck, and the results were published in the journal Physical Review Letters.
