Abstract

Quantum mechanics is inherently probabilistic in light of Born's rule. Using quantum circuits as probabilistic generative models for classical data exploits their superior expressibility and efficient direct sampling ability. However, training of quantum circuits can be more challenging compared to classical neural networks due to the lack of an efficient differentiable learning algorithm. We devise an adversarial quantum-classical hybrid training scheme via coupling a quantum circuit generator and a classical neural network discriminator together. After training, the quantum circuit generative model can infer missing data with quadratic speed-up via amplitude amplification. We numerically simulate the learning and inference of generative adversarial quantum circuits using the prototypical bars-and-stripes dataset. Generative adversarial quantum circuits are a fresh approach to machine learning which may enjoy the practically useful quantum advantage of near-term quantum devices.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In many cases generators can be chosen such that only real amplitudes are generated.

    “In many cases generators can be chosen such that only real amplitudes are generated, see for instance [70].”
  • Trainability can change depending on the variational ansatz type and cost function choice.

    “This can change depending on the variational ansatz type and cost function choice [70].”
  • The alternating blocks ansatz's motivation is to entangle qubits locally first and gradually form a correlated state by interleaving subblocks, which helps improve trainability while maintaining high expressibility.

    “The motivation behind ABA is that we want to entangle qubits locally first, and gradually form a correlated state by interleaving subblocks.This helps to improve trainability of the circuit together while maintaining high expressibility [70,164].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
