Tolerant Testing of Stabilizer States with Mixed State Inputs
Vishnu Iyer, Daniel Liang
We study the problem of tolerant testing of stabilizer states. In particular, we give the first such algorithm that accepts mixed state inputs. Formally, given a mixed state th…

Pseudoentanglement Ain't Cheap
Sabee Grewal, Vishnu Iyer, William Kretschmer +1
We show that any pseudoentangled state ensemble with a gap of bits of entropy requires non-Clifford gates to prepare. This bound is tight up to polylogarithmic factors i…

Agnostic Tomography of Stabilizer Product States
Sabee Grewal, Vishnu Iyer, William Kretschmer +1
We define a quantum learning task called agnostic tomography, where given copies of an arbitrary state and a class of quantum states , the goal is to output a succ…
