Efficient Learning of Quantum States Prepared With Few Non-Clifford Gates II: Single-Copy Measurements
Sabee Grewal, Vishnu Iyer, William Kretschmer +1
Recent work has shown that -qubit quantum states output by circuits with at most single-qubit non-Clifford gates can be learned to trace distance using $\mathsf{poly}(n,…

Efficient Learning of Quantum States Prepared With Few Non-Clifford Gates
Sabee Grewal, Vishnu Iyer, William Kretschmer +1
We give a pair of algorithms that efficiently learn a quantum state prepared by Clifford gates and non-Clifford gates. Specifically, for an -qubit state …

Improved Stabilizer Estimation via Bell Difference Sampling
Sabee Grewal, Vishnu Iyer, William Kretschmer +1
We study the complexity of learning quantum states in various models with respect to the stabilizer formalism and obtain the following results: - We prove that -gates are…
