Non-linear magneto-optic and self polarization rotation by superposition of states
Non-linear magneto-optic self polarization rotation superposition of states Optics
2012/4/24
We report the observation of enhanced magneto-optic rotation as the coherent superposition of different hyperfine states is established in an atomic sample. The polarization rotation near the two phot...
Quantum Filtering (Quantum Trajectories) for Systems Driven by Fields in Single Photon States and Superposition of Coherent States
Quantum Trajectory Superposition of Coherent States Single Photon States
2011/10/8
Abstract: We derive the stochastic master equations, that is to say, quantum filters, and master equations for an arbitrary quantum system probed by a continuous-mode bosonic input field in two types ...

Abstract: The purpose of this paper is to determine quantum master and filter equations for systems coupled to fields in certain non-classical continuous-mode states. Specifically, we consider two typ...
Superposition states of ultracold bosons in rotating rings with a weak potential barrier
Superposition states ultracold bosons weak potential barrier
2010/11/23
We study ultracold bosons in a one-dimensional rotating ring lattice with a weak potential barrier well below unit filling. Due to the potential barrier the eigenstates are superpositions of different...
Necessity of Superposition of Macroscopically Distinct States for Quantum Computational Speedup
Necessity of Superposition Macroscopically Distinct States Quantum Computational Speedup
2010/10/21
For quantum computation, we investigate the conjecture that superposition of macroscopically
distinct states is necessary for large quantum speedup. Although this conjecture was supported for a circu...

Quantum state engineering coherent superposition photon subtraction
2010/10/19
We study a coherent superposition tˆa + rˆa† of field annihilation and creation operator acting on continuous variable systems and propose its application for quantum state engineering...
Spacetime rejects superposition due to discreteness
rejects superposition discrete spacetime quantum collapse
2010/3/18
The existence of a minimum size of spacetime is generally considered as an indispensable element in a complete theory of quantum gravity. In this essay we will analyze one of its implications for qua...
Decoherence, Einselection and Classicality of a Macroscopic Quantum Superposition generated by Quantum Cloning
Decoherence Einselection and Classicality Macroscopic Quantum Superposition Quantum Cloning
2010/4/8
The high resilience to de-coherence shown by a recently discovered Macroscopic Quantum Superposition (MQS) generated by a quantum injected optical parametric amplifier (QI-OPA) and involving a number ...
Quantum computation with mesoscopic superposition states

2010/10/13
We present a strategy to engineer a simple cavity-QED two-bit universal quantum gate using
mesoscopic distinct quantum superposition states. The dissipative effect on decoherence and amplitude dampin...

Phase Distribution of the Output of Jaynes-Cummings Model with the Superposition of Squeezed Displaced Fock States
Non-classical field states squeezed displaced Fock states Wigner quasi-probability function phase distribution JCM
2010/4/9
The Wigner quasi-probability function for the superposition of squeezed displaced Fock states (SDFS's) is reviewed. The interaction of these states with a two-level atom in cavity with the presence of...
