Decoupling Spectral Gaps from Entanglement Complexity in Quantum Annealing
Roopayan Ghosh, Sougato Bose
Exponentially small spectral gaps are the central obstacle to adiabatic quantum annealing, yet whether such bottlenecks demand correspondingly complex entanglement remains unclear.…
Observation of magnetic quantum phase crossovers in a semiconductor spin ladder
Elizaveta Morozova, Xin Zhang, Utso Bhattacharya +9
Understanding collective phases of strongly correlated quantum magnets relies on theoretically tractable model systems with precise microscopic control. Antiferromagnetic spin ladd…
Robust Genuine Multipartite Entanglement in Two Walker Quantum Walks
Sandipan Hazra, Tamoghna Das, Sougato Bose +1
Discrete-time quantum walks provide a versatile framework for investigating the generation, redistribution, and transport of quantum correlations in composite quantum systems. Here…
Spin Chain Quantum Communication on a Trapped-Ion Processor
Madhumita Sarkar, Trinity Pointon, Sougato Bose
Efficient communication between distant qubits is one of the central challenges in scaling quantum processors. Although engineered spin chain protocols have been extensively invest…
Learning Topological Quantum Phases from Limited Subsystems
Mehran Khosrojerdi, Sougato Bose, Alessandro Cuccoli +3
Characterizing quantum topological phases requires measuring non-local string order parameters, demanding access to the full system, which is often experimentally unfeasible. In th…
Self-Attention for Quantum Entanglement Prediction
Anuj Gore, Roopayan Ghosh, Dylan Lewis +1
Quantum entanglement is a powerful resource for quantum-enhanced technologies. However, its reliable quantification remains challenging due to the exponential scaling of the Hilber…
