EPJ D - Not one, not two, not three, but four clones!

First quantum cloning machine to produce four copies

Xi-Jun Ren and Yang Xiang from Henan Universities in China, in collaboration with Heng Fan at the Institute of Physics of the Chinese Academy of Sciences, have produced a theory for a quantum cloning machine able to produce several copies of the state of a particle at atomic or sub-atomic scale, or quantum state, in an article published in EPJ D. This could have implications for quantum information processing methods used, for example, in message encryption systems.

EPJ D - Quantum teleportation analysed by mathematical separation tool

Scientists from the University of Vienna’s Faculty of Physics in Austria recently gave a theoretical description of teleportation phenomena in sub-atomic scale physical systems, in a publication in the European Physical Journal D.

For the first time, the Austrian team proved that mathematical tools give us the freedom to choose how to separate out the constituting matter of a complex physical system by selectively analysing its so-called quantum state. That is the state in which the system is found when performing measurement, which can either be entangled or not.

EPJ D - Speedier Quantum Logic

EPJD - Speedier Quantum Logic

Quantum information processing requires logical operations with multiple quantum bits. One route to this goal is controlling each qubit with a time-dependent external magnetic field. In this recent paper published in EPJ D, Heule et al. describe ways to perform logical operations on an ENTIRE superconducting qubit chain by controlling just ONE of the end qubits of the chain.

EPJ D - 'Measurement of Quantum Mechanical Operators' Revisited

Quantum mechanical measurements are often assumed to be accurate and repeatable. However, due to a fundamental result of Wigner (1952) and Araki and Yanase (1961), we now know that there are limitations to these properties in the presence of aconserved quantity that does not commute with the observable to be measured. Despite its importance and impact on quantum technologies, the full scope of this so-called WAY theorem has remained unclear.

EPJ D - Feshbach resonances in the 6Li-40K Fermi-Fermi mixture: Elastic versus inelastic interactions

Interaction control in a trapped Fermi-Fermi mixture of 6Li and 40K atoms via a magnetically tuned Feshbach resonance.

(Cold Quantum Matter - EuroQUAM special issue)

Ultracold mixtures of two fermionic species hold great promise for synthesizing novel types of few and many-body quantum states. Magnetically tunable Feshbach resonances are the key to controlling the interaction in such systems. In this article in EPJD, Naik et al. present a state-of-the-art characterization of Feshbach resonances in the Fermi-Fermi mixture of 6Li-40K atoms, in particular concerning the interplay of both elastic and inelastic scattering.

EPJ D – Nanodroplets make perfect hosts

Modeling the formation of alkali clusters attached to helium nanodroplets and the abundance of high-spin states

Helium nanodroplets provide a unique matrix for the spectroscopy of embedded atom species. In this recent paper in EPJD, Bünermann and Stienkemeier demonstrate a new model of how effects such as droplet shrinking, momentum transfer and cluster desorption affect the pick-up statistics of alkali atoms in helium nanodroplets.

EPJ D - Reshaping Quantum Light

EPJ D - Reshaping Quantum Light

A photon is not a point: its wavepacket stretches out in space. In the classical limit, this spatial profile is governed by Maxwell's equations, and reshaping it has been a goal in optics since Galileo's invention of the telescope. In this paper, Morizur and his colleagues describe a new Unitary Programmable Mode Converter, a device capable of changing the spatial shape of quantum light at will without introducing loss in the beam.

Ions that love DNA to bits

Low energy carbon ions have been directed to small DNA strand. The results provide new information of the mechanisms of DNA damage during ion beam therapy, also called hadron therapy.

EPJ D – Measurements in the hot spot of a plasma

Measurements in the hot spot of a plasma

A group of researchers in Greifswald, Germany, measured the electron concentration and electron temperature in the active discharge zone of a self-organized plasma jet. Self-organized discharge patterns are shown as time averaged top view in the picture.

Miniaturized non-thermal plasma jets are an emerging technique for surface treatments at ambient pressure, such as cleaning, activation, etching, films deposition and more.

The authors of this EPJ D paper used two independent approaches: spectroscopy and a two-dimensional fluid model calculation of a discharge filament. The results from the two methods are consistent and indicate electron concentrations between 2.2 and 3.3×1014 cm-3. This work represents a first step towards a thorough physical description of the discharge dynamics and energy transport to gain a better understanding of self-organization effects in non thermal plasma jets.
