Entanglement dynamics via Geometric phases in Trapped-ions
Dharmaraj Ramachandran, Ganesh Hanchanahal, Radhika Vathsan
Trapped-ion systems are a leading platform for quantum computing. The Mølmer-Sørensen (MS) gate is a widely used method for implementing controlled interactions in multipartite sys…
A Sharp Geometric Measure of Entanglement
Dharmaraj Ramachandran, Radhika Vathsan
Despite their elegance and widespread use, the current Geometric Measures (GMs) of entanglement exhibit a significant limitation: they fail to effectively distinguish Local Unitary…
Robust entanglement measure for mixed quantum states
Dharmaraj Ramachandran, Aditya Dubey, Subrahmanyam S. G. Mantha +1
We introduce an entanglement measure, the Modified Bloch Norm (MBN), for finite-dimensional bipartite mixed states, based on the improved Bloch matrix criteria. MBN is demonstrated…
Emergence of Classicality in Stern-Gerlach Experiment via Self-Gravity
Sourav Kesharee Sahoo, Radhika Vathsan, Tabish Qureshi
Emergence of classicality from quantum mechanics, a hotly debated topic, has had no satisfactory resolution so far. Various approaches including decoherence and gravitational inter…
A Riemannian Genuine Measure of Entanglement for Pure States
Dharmaraj Ramachandran, Radhika Vathsan
While several measures exist for entanglement of multipartite pure states, a true entanglement measure for mixed states still eludes us. A deeper study of the geometry of quantum s…
Testing Gravitational Self-interaction via Matter-Wave Interferometry
Sourav Kesharee Sahoo, Ashutosh Dash, Radhika Vathsan +1
The Schrodinger-Newton equation has frequently been studied as a nonlinear modification of the Schrodinger equation incorporating gravitational self-interaction. However, there is…
Aspects of Complementarity and Uncertainty
Radhika Vathsan, Tabish Qureshi
The two-slit experiment with quantum particles provides many insights into the behaviour of quantum mechanics, including Bohr's complementarity principle. Here we analyze Einstein'…
Einstein's Recoiling Slit Experiment, Complementarity and Uncertainty
Tabish Qureshi, Radhika Vathsan
We analyze Einstein's recoiling slit experiment and point out that the inevitable entanglement between the particle and the recoiling-slit was not part of Bohr's reply. We show tha…
