A Cutting-plane Method for Semidefinite Programming with Potential Applications on Noisy Quantum Devices
Jakub Marecek, Albert Akhriev
There is an increasing interest in quantum algorithms for optimization problems. Within convex optimization, interior-point methods and other recently proposed quantum algorithms a…
Quantum State Tomography as a Bilevel Problem, Utilizing I-Q Plane Data
Georgios Korpas, Jakub Marecek
It is natural to ask how to utilize actual measurements, such as the so-called IQ-plane data obtained in the dispersive readout of transmon qubits, in the estimation of the state o…
Weak Measurement effects on dynamics of quantum correlations in a Two-atom System in Thermal Reservoirs
N. Ananth, R. Muthuganesan, V. K. Chandrasekar
The dynamical behavior of quantum correlations captured by different forms Measurement-Induced Nonlocality (MIN) between two atoms coupled with thermal reservoirs is investigated a…
High finesse microcavities in the optical telecom O-band
Jan Fait, Stefan Putz, Georg Wachter +4
Optical microcavities allow to strongly confine light in small mode volumes and with long photon lifetimes. This confinement significantly enhances the interaction between light an…
Quantum Technology for Military Applications
Michal Krelina
Quantum technology is an emergent and potentially disruptive discipline, with the ability to affect many human activities. Quantum technologies are dual-use technologies, and as su…
From Rényi Entropy Power to Information Scan of Quantum States
Petr Jizba, Jacob Dunningham, Martin Prokš
In the estimation theory context, we generalize the notion of Shannon's entropy power to the Rényi-entropy setting. This not only allows to find new estimation inequalities, such a…
