XXI Householder Symposium on Numerical Linear Algebra

I'm attending the 2022 Householder Symposium.

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.

FABLE: Fast Approximate Quantum Circuits for Block-Encodings

Fast synthesis of quantum circuits for approximate block-encodings.

Explicit Quantum Circuits for Block Encodings of Certain Sparse Matrices

We provide explicit quantum circuits for the block encoding of certain sparse matrices.

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.


F3C or Fast Free Fermion Compiler is a quantum compiler of Hamiltonian simulation of spin systems that can be mapped to free fermions.


F3C++ is an object-oriented, fully templated C++ package for compiling time-evolution quantum circuits of spin Hamiltonians that can be mapped to free fermions


QCLAB is an object-oriented MATLAB toolbox for creating and representing quantum circuits.
