Converting second quantized operators to matrix form and back#

The second_quantization package provides tools for working with second quantized operators in quantum many-body systems. It allows you to:

  • Convert second quantized expressions to matrix representations

  • Work with different basis states and fermion/boson operators

  • Analyze quantum many-body systems including quantum dots and superconducting devices

  • Perform time evolution and spectroscopic calculations

Quick Start#

Install the package and start exploring quantum many-body systems:

import second_quantization as sq

# Create a Hilbert space with 2 orbitals
hilbert = sq.HilbertSpace(n_orbitals=2)

# Define creation and annihilation operators
c_dag = hilbert.creation_operator(0, spin='up')
c = hilbert.annihilation_operator(0, spin='up')

# Convert to matrix form
matrix = hilbert.to_matrix(c_dag * c)
