Field-Space Entanglement Dynamics Between Tunnel-Coupled Luttinger Liquids
Léonce Dupays, Taufiq Murtadho, Bi Hong Tiang +2
Entanglement dynamics depend not only on how a quantum system is partitioned, but critically on how interactions across that partition are structured. For a spatial bipartition of…
Double-Bracket Algorithmic Cooling
Mohammed Alghadeer, Khanh Uyen Giang, Shuxiang Cao +6
Algorithmic cooling shows that it is possible to locally reduce the entropy of a qubit belonging to an isolated ensemble such as nuclear spins in molecules or nitrogen-vacancy cent…
Extensive entanglement between coupled Tomonaga-Luttinger liquids in and out of equilibrium
Taufiq Murtadho, Marek Gluza, Nelly H. Y. Ng
Quantum entanglement exists in nature but is absent in classical physics, hence it fundamentally distinguishes quantum from classical theories. While entanglement is routinely obse…
Measurement of total phase fluctuation in cold-atomic quantum simulators
Taufiq Murtadho, Federica Cataldini, Sebastian Erne +4
Studying the dynamics of quantum many-body systems is often constrained by the limitations in probing relevant observables, especially in continuous systems. A powerful method to g…
Systematic analysis of relative phase extraction in one-dimensional Bose gases interferometry
Taufiq Murtadho, Marek Gluza, Khatee Zathul Arifa +3
Spatially resolved relative phase measurement of two adjacent 1D Bose gases is enabled by matter-wave interference upon free expansion. However, longitudinal dynamics is typically…
