Quantum dynamics simulations beyond the coherence time on NISQ hardware by variational Trotter compression
Noah F. Berthusen, Thaís V. Trevisan, Thomas Iadecola +1
We demonstrate a post-quench dynamics simulation of a Heisenberg model on present-day IBM quantum hardware that extends beyond the coherence time of the device. This is achieved us…
Symmetry-Protected Infinite-Temperature Quantum Memory from Subsystem Codes
Julia Wildeboer, Thomas Iadecola, Dominic J. Williamson
We study a mechanism whereby quantum information present in the initial state of a quantum many-body system can be protected for arbitrary times due to a combination of symmetry an…
Observation of a symmetry-protected topological time crystal with superconducting qubits
Xu Zhang, Wenjie Jiang, Jinfeng Deng +15
We report the observation of a symmetry-protected topological time crystal, which is implemented with an array of programmable superconducting qubits. Unlike the time crystals repo…
Benchmarking variational quantum eigensolvers for the square-octagon-lattice Kitaev model
Andy C. Y. Li, M. Sohaib Alam, Thomas Iadecola +8
Quantum spin systems may offer the first opportunities for beyond-classical quantum computations of scientific interest. While general quantum simulation algorithms likely require…
Rainbow Scars: From Area to Volume Law
Christopher M. Langlett, Zhi-Cheng Yang, Julia Wildeboer +3
Quantum many-body scars (QMBS) constitute a new quantum dynamical regime in which rare "scarred" eigenstates mediate weak ergodicity breaking. One open question is to understand th…
Adaptive variational quantum eigensolvers for highly excited states
Feng Zhang, Niladri Gomes, Yongxin Yao +2
Highly excited states of quantum many-body systems are central objects in the study of quantum dynamics and thermalization that challenge classical computational methods due to the…
