Computers are about to lose that annoying 'loading' lag by using laser light patterns the second they make a move.

The Takeaway
In current computers, there is a constant delay as the processor waits to retrieve information from memory. This new method uses the high-dimensional interference patterns produced by physical systems—like lasers—as the memory key itself, allowing the system to 'find' the data at the exact same time it decides to look for it.
From the abstract
Physical selectors (lasers choosing a mode, Ising machines settling on a ground state, condensates occupying a spin state) produce high-dimensional signatures at the moment of decision: full field amplitudes, multimode interference patterns, or scattering responses. These signatures are richer than the winner's index, yet they are routinely discarded. We show that when the signatures are repeatable across trials (stereotyped) and linearly independent across routes, a single linear decoder compil
