Coherent feedback cooling of a nanomechanical membrane with atomic spins
Gian-Luca Schmid, Chun Tat Ngai, Maryse Ernzer +3
Coherent feedback stabilises a system towards a target state without the need of a measurement, thus avoiding the quantum backaction inherent to measurements. Here, we employ optic…
A chiral one-dimensional atom using a quantum dot in an open microcavity
Nadia O. Antoniadis, Natasha Tomm, Tomasz Jakubczyk +6
In nanostructures, the light-matter interaction can be engineered to be chiral. In the fully quantum regime, a chiral one-dimensional atom, a photon propagating in one direction in…
Quantum Fokker-Planck Master Equation for Continuous Feedback Control
Björn Annby-Andersson, Faraj Bakhshinezhad, Debankur Bhattacharyya +4
Measurement and feedback control are essential features of quantum science, with applications ranging from quantum technology protocols to information-to-work conversion in quantum…
The time-energy uncertainty relation for quantum events
Matteo Fadel, Lorenzo Maccone
Textbook quantum mechanics treats time as a classical parameter, and not as a quantum observable with an associated Hermitian operator. For this reason, to make sense of usual time…
A thermodynamically consistent Markovian master equation beyond the secular approximation
Patrick P. Potts, Alex Arash Sand Kalaee, Andreas Wacker
Markovian master equations provide a versatile tool for describing open quantum systems when memory effects of the environment may be neglected. As these equations are of an approx…
Full multipartite steering inseparability, genuine multipartite steering and monogamy for continuous variable systems
Run Yan Teh, Manuel Gessner, Margaret D. Reid +1
We derive inequalities sufficient to detect the genuine -partite steering of distinct systems. Here, we are careful to distinguish between the concepts of full -partite s…
Entanglement of Local Hidden States
Matteo Fadel, Manuel Gessner
Steering criteria are conditions whose violation excludes the possibility of describing the observed measurement statistics with local hidden state (LHS) models. When the available…
Detecting Einstein-Podolsky-Rosen steering in non-Gaussian spin states from conditional spin-squeezing parameters
Jiajie Guo, Feng-Xiao Sun, Daoquan Zhu +3
We present an experimentally practical method to reveal Einstein-Podolsky-Rosen steering in non-Gaussian spin states by exploiting a connection to quantum metrology. Our criterion…
Superradiant many-qubit absorption refrigerator
Michal Kloc, Kurt Meier, Kimon Hadjikyriakos +1
We show that the lower levels of a large-spin network with a collective anti-ferromagnetic interaction and collective couplings to three reservoirs may function as a quantum absorp…
Quantum Interference of Identical Photons from Remote GaAs Quantum Dots
Liang Zhai, Giang N. Nguyen, Clemens Spinnler +6
Photonic quantum technology provides a viable route to quantum communication, quantum simulation, and quantum information processing. Recent progress has seen the realisation of bo…
High quality-factor diamond-confined open microcavity
Sigurd Flågan, Daniel Riedel, Alisa Javadi +3
With a highly coherent, optically addressable electron spin, the nitrogen vacancy (NV) centre in diamond is a promising candidate for a node in a quantum network. However, the NV c…
Optically driving the radiative Auger transition
Clemens Spinnler, Liang Zhai, Giang N. Nguyen +8
In a radiative Auger process, optical decay is accompanied by simultaneous excitation of other carriers. The radiative Auger process gives rise to weak red-shifted satellite peaks…
Quantum mean-square predictors and thermodynamics
Marcelo Janovitch, Gabriel T. Landi
Thermodynamic quantities, such as heat and work, are not functions of state, but rather of the process undergone by a physical system. Assessing them can therefore be difficult, si…
Number-phase uncertainty relations and bipartite entanglement detection in spin ensembles
Giuseppe Vitagliano, Matteo Fadel, Iagoba Apellaniz +4
We present a method to detect bipartite entanglement based on number-phase-like uncertainty relations in split spin ensembles. First, we derive an uncertainty relation that plays t…
Machine Learning Universal Bosonic Functionals
Jonathan Schmidt, Matteo Fadel, Carlos L. Benavides-Riveros
The one-body reduced density matrix plays a fundamental role in describing and predicting quantum features of bosonic systems, such as Bose-Einstein condensation. The recently…
Entanglement quantification in atomic ensembles
Matteo Fadel, Ayaka Usui, Marcus Huber +2
Entanglement measures quantify nonclassical correlations present in a quantum system, but can be extremely difficult to calculate, even more so, when information on its state is li…
Stabilization of multi-mode Schrodinger cat states via normal-mode dissipation engineering
Petr Zapletal, Andreas Nunnenkamp, Matteo Brunelli
Non-Gaussian quantum states have been deterministically prepared and autonomously stabilized in single- and two-mode circuit quantum electrodynamics architectures via engineered di…
Violating the Thermodynamic Uncertainty Relation in the Three-Level Maser
Alex Arash Sand Kalaee, Andreas Wacker, Patrick P. Potts
Nanoscale heat engines are subject to large fluctuations which affect their precision. The Thermodynamic Uncertainty Relation (TUR) provides a trade-off between output power, fluct…
Probabilistically Violating the First Law of Thermodynamics in a Quantum Heat Engine
Timo Kerremans, Peter Samuelsson, Patrick P. Potts
Fluctuations of thermodynamic observables, such as heat and work, contain relevant information on the underlying physical process. These fluctuations are however not taken into acc…
Bell correlations in a split two-mode-squeezed Bose-Einstein condensate
Jonas Kitzinger, Xin Meng, Matteo Fadel +4
We propose and analyze a protocol for observing a violation of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality using two spatially separated Bose-Einstein condensates (BECs).…
Control of Stochastic Quantum Dynamics by Differentiable Programming
Frank Schäfer, Pavel Sekatski, Martin Koppenhöfer +2
Control of the stochastic dynamics of a quantum system is indispensable in fields such as quantum information processing and metrology. However, there is no general ready-made appr…
