Title: All possible bipartite positive-operator-value measurements of two-photon polarization states

Abstract

Here we propose an implementation of all possible positive-operator-value measures (POVMs) of two-photon polarization states. POVMs are the most general class of quantum measurements. Our setup requires linear optics, Bell state measurements, and an entangled three-photon ancilla state, which can be prepared separately and in advance (or 'off-line'). As an example we give the detailed settings for a simultaneous measurement of all four Bell states for an arbitrary two-photon polarization state, which is impossible with linear optics alone.

  • Positive-operator-value measures (POVM's) are the most general class of quantum measurements. We propose a setup in which all possible POVM's of a single-photon polarization state (corresponding to all possible sets of two-dimensional Kraus operators) can be implemented easily using linear optics elements. This method makes it possible to experimentally realize any projective orthogonal, projective nonorthogonal or nonprojective sets of any number of POVM operators. Furthermore, our implementation only requires vacuum ancillas and is deterministic rather than probabilistic. Thus it realizes every POVM with the correct set of output states. We give the settings required to implement two different well-known nonorthogonalmore » projective POVM's.« less
  • In this paper we describe a scheme for performing a nonorthogonal projective positive-operator-value measurement of any arbitrary single-photon polarization input state with unit probability of success. While this probability is reached in the limit of infinite cycles of states through the apparatus, only one actual physical setup is required for a feasible implementation. Specifically, our setup implements a set of three nonorthogonal measurement operators at angles of 120 deg. to each other.
  • The absence of divergences and singularities in effectively two-dimensional field theory induced by a superstrong magnetic field is demonstrated for the example where loop diagrams involving two vector and two pseudovector vertices are calculated. The form of effective low-energy Lagrangians for ({gamma}{nu}{nu}) and (a{nu}{nu}) interactions in a superstrong magnetic field is presented. The role of photon and axion decays to neutrinos in the early universe is discussed.
  • A separable approximation T/sup (//sup S//sup )/ to the two-body T matrix of the form = +..sigma../sup S//sub s//sub //sub = //sub 1/ (1-..gamma../sub s/)/sup -1/ is examined, where V is the Reid soft core potential, GAMMA/sub s/ are the Weinberg eigenstates of the operator G/sub 0/(E)V for positive energy E, and ..gamma../sub s/(E) are the corresponding discrete complex eigenvalues. General projection techniques which improve the convergence of the sum above are considered. For the triplet state a nonlocal potential U is defined which in the l = 0 channel represents the effect of the tensor coupling to the lmore » = 2 channel. It is found that the presence of U in the triplet state is responsible for the increased number of terms needed in the separable representation of T, as compared to the representation in the singlet state, where U is absent. The effect of U is largest for momenta less than 1 or 2 fm/sup -1/. .AE« less
  • A bipartite Bell inequality is derived which is maximally violated on the two-qubit state space if measurements describable by positive operator valued measure (POVM) elements are allowed, rather than restricting the possible measurements to projective ones. In particular, the presented Bell inequality requires POVMs in order to be maximally violated by a maximally entangled two-qubit state. This answers a question raised by N. Gisin [in Quantum Reality, Relativistic Causality, and Closing the Epistemic Circle: Essays in Honour of Abner Shimony, edited by W. C. Myrvold and J. Christian (Springer, The Netherlands, 2009), pp. 125-138].
