Ferromagnetic transition in a chiral spin chain
Yuan Xiao, Rimika Jaiswal, Oleg A. Starykh +1
We study the zero-temperature properties of a spin- Heisenberg chain with an additional three-site chiral term of strength . The model is known to be integrable and previou…
Agents' Last Exam
Yiyou Sun, Xinyang Han, Weichen Zhang +306
Recent AI systems have achieved strong results on a wide range of benchmarks, yet these gains have not translated into economically meaningful deployment across many professional d…
MoSAIC: Scalable Probabilistic Error Cancellation via Variational Blockwise Noise Aggregation
Maya Ma, Rimika Jaiswal, Murphy Yuezhen Niu
Quantum error mitigation is essential for extracting trustworthy results from noisy intermediate-scale quantum (NISQ) processors. Yet, current approaches face a core scalability bo…
Simulating a quasiparticle on a quantum device
Rimika Jaiswal, Izabella Lovas, Leon Balents
We propose a variational approach to explore quasiparticle excitations in interacting quantum many-body systems, motivated by the potential in leveraging near-term noisy intermedia…
