Beyond Commutativity: Redesigning Trotter Decomposition via Local Symmetry
Naoki Negishi, Bo Yang
The product formula, commonly known as Trotter decomposition, is a central tool for digital quantum simulation, whose performance depends critically on how the Hamiltonian is parti…
A Robust Large-Period Discrete Time Crystal and its Signature in a Digital Quantum Computer
Tianqi Chen, Ruizhe Shen, Ching Hua Lee +2
Discrete time crystals (DTCs) are novel out-of-equilibrium quantum states of matter which break time translational symmetry. DTCs have been extensively realized in experiments, par…
Robust Simulations of Many-Body Symmetry-Protected Topological Phase Transitions on a Quantum Processor
Ruizhe Shen, Tianqi Chen, Bo Yang +2
Topology and symmetry play critical roles in characterizing quantum phases of matter. Recent advancements have unveiled symmetry-protected topological (SPT) phases in many-body sys…
Observation of the non-Hermitian skin effect and Fermi skin on a digital quantum computer
Ruizhe Shen, Tianqi Chen, Bo Yang +1
Non-Hermitian physics has attracted considerable attention in recent years, particularly the non-Hermitian skin effect (NHSE) for its extreme sensitivity and non-locality. While th…
