Quantum pixel representations and compression for N-dimensional images

We introduce a uniform framework for quantum pixel representations that encompasses many of the popular image representations proposed in the literature. We propose a novel circuit implementation with an efficient compression algorithm.

Algebraic Compression of Quantum Circuits for Hamiltonian Evolution

By analyzing the Hamiltonian algebra, we show that Trotter circuits for simulation of free fermions are efficiently compressible. Our method is applied to an adiabatic state preparation experiment.


QPIXL++ is a quantum image pixel library that supports the compilation, simulation and compression of quantum circuits for Flexible Representations of Quantum Images.

An Algebraic Quantum Circuit Compression Algorithm for Hamiltonian Simulation

We present a numerical algorithm for compressing quantum circuits related to Hamiltonian simulation.
