Minimum uncertainty states and squeezed states from the sum uncertainty relation
Yatindra Kumar, Yashraj Jha, Namrata Shukla
Heisenberg uncertainty relation is at the origin of understanding minimum uncertainty states and squeezed states of light. In the recent past, sum uncertainty relation was formulat…
Uncertainty Relation for Non-Hermitian Systems
Namrata Shukla, Ranjan Modak, Bhabani Prasad Mandal
We construct uncertainty relation for arbitrary finite dimensional PT invariant non-Hermitian quantum systems within a special inner product framework. This construction is led by…
Squeezed comb states
Namrata Shukla, Stefan Nimmrichter, Barry C. Sanders
Continuous-variable codes are an expedient solution for quantum information processing and quantum communication involving optical networks. Here we characterize the squeezed comb,…
Quantum tetrachotomous states: Superposition of four coherent states on a line in phase space
Namrata Shukla, Naeem Akhtar, Barry C. Sanders
The well studied quantum optical Schrödinger cat state is a superposition of two distinguishable states, with quantum coherence between these macroscopically distinguishable states…
State-independent preparation uncertainty relations
Hubert de Guise, Lorenzo Maccone, Barry C. Sanders +1
The standard state-dependent Heisenberg-Robertson uncertainly-relation lower bound fails to capture the quintessential incompatibility of observables as the bound can be zero for s…
Large Polarization Squeezing in Non-Degenerate Parametric Amplification of Coherent Radiation
Namrata Shukla, Ranjana Prakash
Polarization squeezing is shown to occur in non-degenerate parametric amplification of coherent light and the degree of squeezing at interaction time can be as large as $1-e^{-…
Polarization squeezing in polarized light
Ranjana Prakash, Namrata Shukla
It is shown that polarized light can be polarization squeezed only if it exhibits sub-Poissonian statistics with the Mandel's Q factor less than -1/2.
Polarization Squeezing in Degenerate Parametric Amplification of Coherent Light
Namrata Shukla, Ranjana Prakash
We study polarization squeezing of a light beam initially in the coherent state using the nonlinear interaction hamiltonian . Fo…
Alteration in Non-Classicality of Light on Passing Through a Linear Polarization Beam Splitter
Namrata Shukla, Ranjana Prakash
We observe the polarization squeezing in the mixture of a two mode squeezed vacuum and a simple coherent light through a linear polarization beam splitter. Squeezed vacuum not bein…
Simultaneous polarization squeezing in polarized N photon state and diminution on a squeezing operation
Namrata Shukla, Ranjana Prakash
We study polarization squeezing of a pure photon number state which is obviously polarized but the mere change in the basis of polarization leads to simultaneous polarization squee…
Construction of models of universe on the Riemann hypothesis
Namrata Shukla
The aim of this note is to remove an implausible assumption in Moser's theorem \cite{JM} to establish our new theorem 1 which gives a lower estimate for the sum on Riemann…
Pancharatnam phase deficit can detect macroscopic entanglement
Namrata Shukla, Arun Kumar Pati
The Pancharatnam phase deficit is defined as the difference between the Pancharat- nam phase acquired by the global system and the sum of the Pancharatnam phases acquired by subsys…
Stronger Error Disturbance Relations for Incompatible Quantum Measurements
Chiranjib Mukhopadhyay, Namrata Shukla, Arun Kumar Pati
We formulate a new error-disturbance relation, which is free from explicit dependence upon variances in observables. This error-disturbance relation shows improvement over the one…
Canonical Distillation of Entanglement
Tamoghna Das, Asutosh Kumar, Amit Kumar Pal +3
Distilling highly entangled quantum states from weaker ones is a process that is crucial for efficient and long-distance quantum communication, and has implications for several oth…
