Phase-Driven Precision Boost in Quantum Compression for Postselected Metrology
Aiham M. Rostom, Saeed Haddadi, Vladimir A. Tomilin
We reveal the noncyclic Pancharatnam phase--arising from the coherent system-meter interaction--as a fundamental criterion that governs the optimal performance of quantum compressi…

Geometric Phase of the Two-Particle Bethe Wavefunction
V. A. Tomilin, A. M. Rostom, L. V. Il'ichov
We consider a problem of geometric phase generation in a system of two interacting bosons confined in a narrow ring potential with a localized defect. Geometric phase emerges from…
