Quantum Inception Score
Motivated by the great success of classical generative models in machine learning, enthusiastic exploration of their quantum version has recently started.
Inference-Based Quantum Sensing
We show that, for a general class of unitary families of encoding, $\mathcal{R}(\theta)$ can be fully characterized by only measuring the system response at $2n+1$ parameters.
Generalized Measure of Quantum Fisher Information
In this work, we present a lower bound on the quantum Fisher information (QFI) which is efficiently computable on near-term quantum devices.

Noise-Induced Barren Plateaus in Variational Quantum Algorithms
Specifically, for the local Pauli noise considered, we prove that the gradient vanishes exponentially in the number of qubits $n$ if the depth of the ansatz grows linearly with $n$.
Cost Function Dependent Barren Plateaus in Shallow Parametrized Quantum Circuits
Variational quantum algorithms (VQAs) optimize the parameters $\vec{\theta}$ of a parametrized quantum circuit $V(\vec{\theta})$ to minimize a cost function $C$.
