  • Variational Quantum Simulation: A Case Study for Understanding Warm Starts

    Author(s): Ricard Puig, Marc Drudis, Supanut Thanasilp, and Zoë Holmes Initialization closer to a solution in variational quantum simulation yields guarantees on initial trainability, but no guarantee of a good minimum. [PRX Quantum 6, 010317] Published Thu Jan 23, 2025

  • Optimal Quantum Circuit Cuts with Application to Clustered Hamiltonian Simulation

    Author(s): Aram W. Harrow and Angus Lowe Circuit cutting, or using small operations on few qubits to simulate larger operations, is now achievable at minimal cost for many operations thanks to a new method and more precise cost bounds. [PRX Quantum 6, 010316] Published Wed Jan 22, 2025

  • Noisy Approach to Intrinsically Mixed-State Topological Order

    Author(s): Ramanjit Sohal and Abhinav Prem Decoherence can be used to generate mixed-state topological orders without analogue in closed systems and with properties useful for quantum information applications. [PRX Quantum 6, 010313] Published Tue Jan 21, 2025

  • Intrinsic Mixed-State Topological Order

    Author(s): Zijian Wang, Zhengzhi Wu, and Zhong Wang A new type of topological order for open quantum systems, which has no pure-state counterpart, is proposed and studied using exactly solvable models. [PRX Quantum 6, 010314] Published Tue Jan 21, 2025

  • Toward a Classification of Mixed-State Topological Orders in Two Dimensions

    Author(s): Tyler D. Ellison and Meng Cheng Emergent generalized symmetries lead to the proof that there exist topological orders intrinsic to mixed states, and examples of these states provide insight into their classifications by premodular anyon theories. [PRX Quantum 6, 010315] Published Tue Jan 21, 2025

  • Sign Problem in Tensor-Network Contraction

    Author(s): Jielun Chen, Jiaqing Jiang, Dominik Hangleiter, and Norbert Schuch Interference, which gives rise to the sign problem in quantum Monte Carlo, also leads to a significant increase in computational hardness in tensor networks. [PRX Quantum 6, 010312] Published Fri Jan 17, 2025
