Physical Review A

Very small optimized phase uncertainties of two-photon coherent states

A. Bandilla, H.‐H. Ritze

Published Jun 1, 1994• 7 citations
Publisher

Abstract

Considering intense two-photon coherent states with minimum phase dispersion, the width of the phase probability distributions based on the Pegg-Barnett formalism, the Wigner function, and the Q function is discussed. Remarkable differences are found in certain regions depending on the mean photon number. These results are compared with the phase uncertainty of phase optimized states.

Phase distribution of nonlinear coherent states

Barnana Roy, P Roy

Using the Pegg-Barnett formalism we study phase properties of nonlinear coherent states. We compute the Pegg-Barnett phase probability distribution of nonlinear coherent states and compare it with phase distributions associated with the Q function and the Wigner function. Squeezing properties of nonlinear coherent states with respect to the number and the phase operator are also studied.

Realistic phase distributions derived from the Wigner function

A. Bandilla, H Ritze

The authors present the radius integrated Wigner function for a general pure state and discuss the coefficients of the different Fourier components. A fast converging expansion of these coefficients is given and its usefulness is shown for coherent light. Remarkable and measurable differences to the Pegg-Barnett formalism appear for weakly excited coherent states while for large excitations both dispersions agree in their leading terms. Large deviations are expected for specially designed two-photon coherent states.

Properties of two-mode squeezed number states

Alexei Vladimirovich Chizhov, B. K. Murzakhmetov

Photon statistics and phase properties of two-mode squeezed number states are studied. It is shown that photon number distribution and Pegg-Barnett phase distribution for such states have similar (N + 1)-peak structure for nonzero value of the difference in the number of photons between modes. Exact analytical formulas for phase distributions based on different phase approaches are derived. The Pegg-Barnett phase distribution and the phase quasiprobability distribution associated with the Wigner function are close to each other, while the phase quasiprobability distribution associated with the Q function carries less phase information.

Phase-coherent states and their squeezing properties

Le‐Man Kuang, Xin Chen

Phase-coherent states associated with the Pegg-Barnett (PB) phase operator formalism are introduced in terms of the algebraic properties of the PB phase theory. The phase-coherent-state representation of the PB phase states and the PB phase operators is obtained. Squeezing properties of these coherent states with respect to the phase quadrature operators are studied. The number-phase squeezing and number-phase uncertainty relations are also investigated in detail for a two-state system. Some new number-phase minimum uncertainty states are found.

Uncertainty Relations for the Number of Photons and the Phase Operator of an Electromagnetic Field for Phase Quantum Superpositions of Coherent States

A. V. Kozlovskiĭ

Abstract We examine various uncertainty relations: (electromagnetic-field phase (the so-called “Pegg–Barnett operator”))–(number of photons), (trigonometric functions of the phase)–(number of photons), and (trigonometric functions of the phase)–(field phase). An electromagnetic field in quantum states of phase superpositions of coherent states, which are general superpositions of two coherent states with identical moduli but arbitrary phases, is considered. The rigorous uncertainty relation (Cauchy inequality) and the soft uncertainty relation (Heisenberg inequality) are examined and compared.

Phase properties of excited coherent states

Ravinder Nath, Satish Kumar Muthu

The phase properties of states generated by excitations on a coherent state have been studied by evaluating the expression for the phase probability distribution, using the recent formalism of Pegg and Barnett in which the existence of a Hermitian optical phase operator has been shown. This distribution has been further used to evaluate the variance of the phase operator and the number - phase uncertainty product.
