Bistability-assisted Mechanical Squeezing and Entanglement
Souvik Agasti, P. Djorwé
We propose a scheme to squeeze mechanical motion and to entangle optical field with mechanical motion in an optomechanical system containing a parametric amplification. The scheme…
Zig-zag dynamics in a Stern-Gerlach spin measurement
Simon Krekels, Christian Maes, Kasper Meerts +1
The one-century-old Stern-Gerlach setup is paradigmatic for a quantum measurement. We visualize the electron trajectories following the Bohmian zig-zag dynamics. This dynamics was…
Simulation of Matrix Product States to Unveil the Initial State Dependency of non-Gaussian Dynamics of Kerr Nonlinearity
Souvik Agasti
We simulate a free dissipative and coherent-driven Kerr nonlinear system using a time-evolving block decimation (TEBD) algorithm, to study the impact of the initial state on the ex…
Simulation of Kerr Nonlinearity: Revealing Initial State Dependency
Souvik Agasti
We simulate coherent driven free dissipative Kerr nonlinear system numerically using time evolving block decimation (TEBD) algorithm and time propagation on the Heisenberg equation…
Argon milling induced decoherence mechanisms in superconducting quantum circuits
J. Van Damme, Ts. Ivanov, P. Favia +12
The fabrication of superconducting circuits requires multiple deposition, etch and cleaning steps, each possibly introducing material property changes and microscopic defects. In t…
Back-Action Evading Measurement in Gravitational Wave Detectors to Overcome Standard Quantum Limit, Using Negative Radiation Pressure
Souvik Agasti, Abhishek Shukla, Milos Nesladek
Aiming at application for gravitational wave (GW) detection, we propose a novel scheme how to obtain quantum back action evading measurements performed on an opto-mechanical cavity…
