Generation of entanglement using a short-wavelength seeded free-electron laser
Saikat Nandi, Axel Stenquist, Asimina Papoulia +25
Quantum entanglement between the degrees of freedom encountered in the classical world is challenging to observe due to the surrounding environment. To elucidate this issue, we inv…
Quantum communication networks with optical vortices
S. Suciu, G. A. Bulzan, T. A. Isdraila +4
Quantum communications bring a paradigm change in internet security by using quantum resources to establish secure keys between parties. Present-day quantum communications networks…
Optimal phase sensitivity of an unbalanced Mach-Zehnder interferometer
Karunesh K. Mishra, Stefan Ataman
In this paper we address the problem of optimizing an unbalanced Mach-Zehnder interferometer, for a given pure input state and considering a specific detection scheme. While the op…
Studying ultrafast Rabi dynamics with a short-wavelength seeded free-electron laser
Saikat Nandi, Edvin Olofsson, Mattias Bertolino +26
Rabi oscillations are periodic modulations of populations in two-level systems interacting with a time-varying field. They are ubiquitous in physics with applications in different…
Quantum Fisher information maximization in an unbalanced interferometer
Stefan Ataman
In this paper we provide the answer to the following question: given an arbitrary pure input state and a general, unbalanced, Mach-Zehnder interferometer, what transmission coeffic…
Interaction-free imaging of multi-pixel objects
Alexandra Maria Palici, Tudor-Alexandru Isdraila, Stefan Ataman +1
Quantum imaging, one of the pillars of quantum technologies, is well-suited to study sensitive samples which require low-light conditions, like biological tissues. In this context,…
Single- versus two-parameter Fisher information in quantum interferometry
Stefan Ataman
In this paper we reconsider the single parameter quantum Fisher information (QFI) and compare it with the two-parameter one. We find simple relations connecting the single paramete…
OAM tomography with Heisenberg-Weyl observables
Alexandra Maria Palici, Tudor-Alexandru Isdraila, Stefan Ataman +1
Photons carrying orbital angular momentum (OAM) are excellent qudits and are widely used in several applications, such as long distance quantum communication, -dimensional telep…
Optimal Mach-Zehnder phase sensitivity with Gaussian states
Stefan Ataman
We address in this work the phase sensitivity of a Mach-Zehnder interferometer with Gaussian input states. A squeezed-coherent plus squeezed vacuum input state allows us to unambig…
Phase sensitivity of a Mach-Zehnder interferometer with single-intensity and difference-intensity detection
Stefan Ataman, Anca Preda, Radu Ionicioiu
Interferometry is a widely-used technique for precision measurements in both classical and quantum contexts. One way to increase the precision of phase measurements, for example in…
Vacuum birefringence detection in all-optical scenarios
Stefan Ataman
In this paper we propose an all-optical vacuum birefringence experiment and evaluate its feasibility for various scenarios. Many petawatt-class lasers became operational and many m…
Spying on photons with photons: quantum interference and information
Stefan Ataman
The quest to have both which-path knowledge and interference fringes in a double-slit experiment dates back to the inception of quantum mechanics (QM) and to the famous Einstein-Bo…
An example of quantum imaging: rendering an object undetectable
Stefan Ataman
In this paper we propose and analyse a Gedankenexperiment involving three non-linear crystals and two objects inserted in the idler beams. We show that, besides the behaviour that…
