More global randomness from less random local gates https://t.co/YtBeKjqqCo Non-Haar local quantum gates can actually lead to more global randomness in #randomcircuits and can be better scramblers.

Usually, one has a hard time keeping up with the state of the art, or is too late. But papers can also be written too early. This work, merging ideas of #randomcircuits with those of the #efficient estimation as in #shadowestimation, is cited only now. https://t.co/kSfrp5YHZM

Not dissimilar from the situation of making use of #tensornetworks to classically simulate noisy quantum #randomcircuits, this work compared the performance of the quantum simulation with time-dependent tensor network techniques.

Our technical contribution is to construct families of #randomcircuits that are highly sensitive to noise, in the sense that even at loglog(n) depth, a whisker beyond #constant, #quantumnoise is seen to super-exponentially rapidly scramble outputs into the maximally-mixed state.
