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…
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…
