Algebraic Compression of Free Fermionic Quantum Circuits: Particle Creation, Arbitrary Lattices and Controlled Evolution

We extend our circuit compression algorithms to free fermionic systems on arbitrary lattices, incorporate particle creation operations, and allow for controlled evolution.

QCLAB++: Simulating Quantum Circuits on GPUs

We report a series benchmarks conducted in NERSC's Perlmutter system using a GPU adaptation of QCLAB++, a light-weight, fully-templated C++ package for quantum circuit simulations.

Exploring Finite Temperature Properties of Materials with Quantum Computers

This paper introduces a two-step protocol to prepare thermal pure quantum states on a quantum computer.

Quantum-parallel vectorized data encodings and computations on trapped-ions and transmons QPUs

This paper proposes a nested state preparation circuit construction with a high degree of quantum parallelism. We test this circuit to load a variety of data sets stemming from applications and process them directly on a real QPU.

Simulating dirty bosons on a quantum computer

We simulate the physics of dirty bosons in 1D on quantum computer and in 2D on a quantum circuit simulator.

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.
