Geometric quantum machine learning of BQPA protocols and latent graph classifiers
Chukwudubem Umeano, V. Elfving, O. Kyriienko·Feb 6, 2024
Geometric quantum machine learning (GQML) aims to embed problem symmetries for learning efficient solving protocols. However, the question remains if (G)QML can be routinely used for constructing protocols with an exponential separation from classica...
Sequential adiabatic generation of chiral topological states
Xie Chen, M. Hermele, David T. Stephen·Feb 5, 2024
In previous work, it was shown that non-trivial gapped states can be generated from a product state using a sequential quantum circuit. Explicit circuit constructions were given for a variety of gapped states at exactly solvable fixed points. In th...
Comparative study of quantum error correction strategies for the heavy-hexagonal lattice

Topological quantum error correction is a milestone in the scaling roadmap of quantum computers, which targets circuits with trillions of gates that would allow running quantum algorithms for real-world problems. The square-lattice surface code has b...
Unsupervised learning of topological non-Abelian braiding in non-Hermitian bands
Yang Long, Haoran Xue, Baile Zhang·Jan 31, 2024
The topological classification of energy bands has laid the foundation for the discovery of various topological phases of matter in recent decades. While previous work focused on real-energy bands in Hermitian systems, recent studies have shifted att...

Fractional quantum Hall (FQH) states are known for their robust topological order and possess properties that are appealing for applications in fault-tolerant quantum computing. An engineered quantum platform would provide opportunities to operate FQ...
Tapestry of dualities in decohered quantum error correction codes
Kaixiang Su, Zhou Yang, Chao-Ming Jian·Jan 30, 2024
Quantum error correction (QEC) codes protect quantum information from errors due to decoherence. Many of them also serve as prototypical models for exotic topological quantum matters. Investigating the behavior of the QEC codes under decoherence shed...
Exponential Quantum Advantages for Practical Non-Hermitian Eigenproblems.
Xiao-Ming Zhang, Yukun Zhang, Wenhao He +1 more·Jan 22, 2024
Non-Hermitian physics has emerged as a rich field of study, with applications ranging from PT-symmetry breaking and skin effects to non-Hermitian topological phase transitions. Yet most studies remain restricted to small-scale or classically tractabl...
Floquet control of interactions and edge states in a programmable quantum simulator
Or Katz, Lei Feng, Diego Porras +1 more·Jan 18, 2024
Quantum simulators based on trapped ions enable the study of spin systems and models with rich dynamical phenomena. The Su-Schrieffer-Heeger (SSH) model for fermions in one dimension is a canonical example that can support a topological insulator pha...
Advantage of Quantum Neural Networks as Quantum Information Decoders
Weishun Zhong, O. Shtanko, R. Movassagh·Jan 11, 2024
A promising strategy to protect quantum information from noise-induced errors is to encode it into the low-energy states of a topological quantum memory device. However, readout errors from such memory under realistic settings is less understood. We ...
