A note on polynomial-time tolerant testing stabilizer states
Srinivasan Arunachalam, Sergey Bravyi, Arkopal Dutt
We show an improved inverse theorem for the Gowers- norm of -qubit quantum states which states that: for every , if the $\textsf{Gowers}(|ψ\rangle,3)^8 \…

Power of sequential protocols in hidden quantum channel discrimination
Sho Sugiura, Arkopal Dutt, William J. Munro +2
In many natural and engineered systems, unknown quantum channels act on a subsystem that cannot be directly controlled and measured, but is instead learned through a controllable s…
