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…
Precision gravimetry via harnessing interaction-induced resonances in optical lattices
Hassan Manshouri, Moslem Zarei, Mehdi Abdi +3
By confining a Bose-Einstein condensate in a vertical lattice subjected to a gravitational potential, we analyze the quantum Fisher information to determine its scaling with respec…
Enhanced image classification via hybridizing quantum dynamics with classical neural networks
Ruiyang Zhou, Saubhik Sarkar, Sougato Bose +1
The integration of quantum computing and machine learning has emerged as a promising frontier in computational science. We present a hybrid protocol which combines classical neural…
Quantum Enhanced Sensitivity through Many-Body Bloch Oscillations
Hassan Manshouri, Moslem Zarei, Mehdi Abdi +2
We investigate the sensing capacity of non-equilibrium dynamics in quantum systems exhibiting Bloch oscillations. By focusing on the resource efficiency of the probe, quantified by…
Exponentially-enhanced quantum sensing with many-body phase transitions
Saubhik Sarkar, Abolfazl Bayat, Sougato Bose +1
Quantum sensors based on critical many-body systems are known to exhibit enhanced sensing capability. Such enhancements typically scale algebraically with the probe size. Going bey…
Ballistic Entanglement Cloud after a Boundary Quench
Bedoor Alkurtass, Abolfazl Bayat, Pasquale Sodano +2
Entanglement has been extensively used to characterize the structure of strongly correlated many-body systems. Most of these analyses focus on either spatial properties of entangle…
