Berry Phase Quantum Thermometer
E. Martin-Martinez, A. Dragan, R. B. Mann +1
We show how Berry phase can be used to construct an ultra-high precision quantum thermometer. An important advantage of our scheme is that there is no need for the thermometer to a…
A bosonic Josephson junction controlled by a single trapped ion
R. Gerritsma, A. Negretti, H. Doerk +3
We theoretically investigate the properties of a double-well bosonic Josephson junction coupled to a single trapped ion. We find that the coupling between the wells can be controll…
Dispersion-based control of modal characteristics for parametric down-conversion in a multimode waveguide
Michal Karpinski, Czeslaw Radzewicz, Konrad Banaszek
We report generation of near-infrared photon pairs in fundamental spatial modes via type-II spontaneous parametric down-conversion in a periodically poled potassium titanyl phospha…
Cold and trapped metastable noble gases
Wim Null Vassen, Claude Cohen-Tannoudji, Michèle Leduc +7
We review experimental and theoretical work on cold, trapped metastable noble gases. We em- phasize the aspects which distinguish work with these atoms from the large body of work…
Quantum privacy witness
Konrad Banaszek, Karol Horodecki, Paweł Horodecki
While it is usually known that the mean value of a single observable is enough to detect entanglement or its distillability, the counterpart of such an approach in the case of quat…
Quantum interferometry with and without an external phase reference
Marcin Jarzyna, Rafal Demkowicz-Dobrzanski
We discuss the role of an external phase reference in quantum interferometry. We point out inconsistencies in the literature with regard to the use of the quantum Fisher informatio…
Sub shot-noise interferometry from measurements of the one-body density
Jan Chwedenczuk, Philipp Hyllus, Francesco Piazza +1
We derive the asymptotic maximum-likelihood phase estimation uncertainty for any interferometric protocol where the positions of the probe particles are measured to infer the phase…
Noninvasiveness and time symmetry of weak measurements
Adam Bednorz, Kurt Franke, Wolfgang Belzig
Measurements in classical and quantum physics are described in fundamentally different ways. Nevertheless, one can formally define similar measurement procedures with respect to th…
Generating Molecular Rovibrational Coherence by Two-Photon Femtosecond Photoassociation of Thermally Hot Atoms
Leonid Rybak, Saieswari Amaran, Liat Levin +5
The formation of diatomic molecules with rotational and vibrational coherence is demonstrated experimentally in free-to-bound two-photon femtosecond photoassociation of hot atoms.…
Immunity of information encoded in decoherence-free subspaces to particle loss
Piotr Migdał, Konrad Banaszek
We demonstrate that for an ensemble of qudits, subjected to collective decoherence in the form of perfectly correlated random SU(d) unitaries, quantum superpositions stored in the…
Entanglement of N distinguishable particles
Tomasz Bigaj
In their 2002 article, Ghirardi, Marinatto and Weber have proposed a formal analysis of the entanglement properties for a system consisting of N distinguishable particles. Their an…
Nonclassical time correlation functions in continuous quantum measurement
Adam Bednorz, Wolfgang Belzig, Abraham Nitzan
A continuous projective measurement of a quantum system often leads to a suppression of the dynamics, known as the Zeno effect. Alternatively, generalized nonprojective, so-called…
Statistical properties of one dimensional attractive Bose gas
Przemyslaw Bienias, Krzysztof Pawlowski, Mariusz Gajda +1
Using classical field approximation we present the first study of statistical properties of one dimensional Bose gas with attractive interaction. The canonical probability distribu…
Fourth moments reveal the negativity of the Wigner function
Adam Bednorz, Wolfgang Belzig
The presence of unique quantum correlations is the core of quantum information processing and general quantum theory. We address the fundamental question of how quantum correlation…
Beyond quantum Fisher information: optimal phase estimation with arbitrary a priori knowledge
Rafal Demkowicz-Dobrzanski
The optimal phase estimation strategy is derived when partial a priori knowledge on the estimated phase is available. The structure of the optimal measurements, estimators and the…
Resonant tunneling controlled by laser and constant electric fields
J. Z. Kaminski, E. Saczuk
We develop the concept of scattering matrix and we use it to perform stable numerical calculations of resonant tunneling of electrons through a multiple potential barrier in a semi…
