Quantum many-body scars with tunable entanglement and Hamiltonian inverse design from ZX-calculus
Marcin Szyniszewski
Diagrammatic languages such as ZX-calculus provide compact and intuitive descriptions of quantum processes and have become established tools for circuit simplification, verificatio…
Automated quantum circuit optimization with randomized replacements
Marcin Szyniszewski, Aleks Kissinger, Noah Linden +1
Quantum circuit optimization - the process of transforming a quantum circuit into an equivalent one with reduced time and space requirements - is crucial for maximizing the utility…
Dynamic syndrome decoder in volume-law phases of hybrid quantum circuits
Dawid Paszko, Marcin Szyniszewski, Arijeet Pal
Phases of matter with volume-law entanglement are frequently observed in quantum circuits and have numerous applications, ranging from deepening our understanding of quantum mechan…
Measurement-induced Lévy flights of quantum information
Igor Poboiko, Marcin Szyniszewski, Christopher J. Turner +3
We explore a model of free fermions in one dimension, subject to frustrated (non-commuting) local measurements across adjacent sites, which resolves the fermions into non-orthogona…
Stable infinite-temperature eigenstates in SU(2)-symmetric nonintegrable models
Christopher J. Turner, Marcin Szyniszewski, Bhaskar Mukherjee +3
Nonintegrable many-body quantum systems typically thermalize at long times through the mechanism of quantum chaos. However, some exceptional systems, such as those harboring quantu…
Stabilization of symmetry-protected long-range entanglement in stochastic quantum circuits
Iosifina Angelidi, Marcin Szyniszewski, Arijeet Pal
Long-range entangled states are vital for quantum information processing and quantum metrology. Preparing such states by combining measurements with unitary gates opened new possib…
