Large-scale quantum simulations of dissipative spin-1/2 Heisenberg chains
João C. Getelina, Andrew Cox, Muhammad Asaduzzaman +4
A quantum many-body system coupled to an environment relaxes to a nonequilibrium steady state that can sustain order with no equilibrium counterpart. Computing such steady states i…

CaRBM: A Fixed-Depth Quantum Algorithm with Partial Correction for Thermal State Preparation
Omar Alsheikh, A. F. Kemper, Ermal Rrapaj +2
We introduce the CaRBM algorithm for fixed-depth thermal state preparation. Our algorithm is based on thermal state purification and uses the Restricted Boltzmann Machine (RBM) blo…

RedCarD: A Quantum Assisted Algorithm for Fixed-Depth Unitary Synthesis via Cartan Decomposition
Omar Alsheikh, Efekan Kökcü, Bojko N. Bakalov +1
A critical step in developing circuits for quantum simulation is to synthesize a desired unitary operator using the circuit building blocks. Studying unitaries and their generators…
