quantax.sampler.ExactSampler#

class quantax.sampler.ExactSampler#

Bases: Sampler

Generate samples directly from exact probability

__init__(state: State, nsamples: int, reweight: float = 2.0, symm: Symmetry | None = None)#
Parameters:

  • state – The state used for computing the wave function and probability

  • nsamples – Number of samples generated per iteration

  • reweight – The reweight factor n defining the sample probability \(|\psi|^n\), default to 2.0

  • symm – The symmetry for computing the full wave function, default to the symmetry of the state.

sweep() → Samples#

Generate new samples by computing the full wave function

property nsamples: int#

Number of samples generated per iteration

property reweight: float#

The reweight factor n defining the sample probability \(|\psi|^n\)

property state: State#

The state used for computing the wave function and probability
