Non-Exponential Behaviour in Logical Randomized Benchmarking
Athena Ceasura, Pavithran Iyer, Joel J. Wallman +1
We construct a gate and time-independent noise model that results in the output of a logical randomized benchmarking protocol oscillating rather than decaying exponentially. To ill…
Sample-optimal classical shadows for pure states
Daniel Grier, Hakop Pashayan, Luke Schaeffer
We consider the classical shadows task for pure states in the setting of both joint and independent measurements. The task is to measure few copies of an unknown pure state in…
Shallow shadows: Expectation estimation using low-depth random Clifford circuits
Christian Bertoni, Jonas Haferkamp, Marcel Hinsche +3
We provide practical and powerful schemes for learning many properties of an unknown n-qubit quantum state using a sparing number of copies of the state. Specifically, we present a…
