Advances in quantum imaging
Hugo Defienne, Warwick P. Bowen, Maria Chekhova +5
Modern imaging technologies are widely based on classical principles of light or electromagnetic wave propagation. They can be remarkably sophisticated, with recent successes rangi…
Standalone mobile quantum memory system
Martin Jutisz, Alexander Erl, Janik Wolters +2
We present the implementation and performance analysis of a portable, rack-mounted standalone warm vapor quantum memory system, that also includes the laser package, control electr…
Benchmarking Variational Quantum Algorithms for Combinatorial Optimization in Practice
Tim Schwägerl, Yahui Chai, Tobias Hartung +2
Variational quantum algorithms and, in particular, variants of the varational quantum eigensolver have been proposed to address combinatorial optimization (CO) problems. Using only…
Imaginary Hamiltonian variational ansatz for combinatorial optimization problems
Xiaoyang Wang, Yahui Chai, Xu Feng +3
Obtaining exact solutions to combinatorial optimization problems using classical computing is computationally expensive. The current tenet in the field is that quantum computers ca…
Emergence of second-order coherence in superfluorescence
Constanze Bach, Felix Tebbenjohanns, Christian Liedl +2
We experimentally investigate the second-order quantum coherence function of a superradiant burst in a cascaded quantum system. We chirally (i.e. direction-dependently) couple roug…
Predicting correlations in superradiant emission from a cascaded quantum system
Felix Tebbenjohanns, Christopher D. Mink, Constanze Bach +2
In recent experiments, a novel type of cascaded quantum system has been realized using nanofiber-coupled cold atomic ensembles. This setup has enabled the study of superradiant dec…
Ambiguous Resonances in Multipulse Quantum Sensing with Nitrogen Vacancy Centers
Lucas Tsunaki, Anmol Singh, Kseniia Volkova +4
Dynamical decoupling multipulse sequences can be applied to solid state spins for sensing weak oscillating fields from nearby single nuclear spins. By periodically reversing the pr…
Warm Start of Variational Quantum Algorithms for Quadratic Unconstrained Binary Optimization Problems
Yahui Chai, Karl Jansen, Stefan Kühn +2
Variational Quantum Eigensolver (VQE) is widely used in near-term hardware. However, their performances remain limited by the poor trainability and are dependent on random paramete…
The Influence of Experimental Imperfections on Photonic GHZ State Generation
Fabian Wiesner, Helen M. Chrzanowski, Gregor Pieplow +3
While the advantages of photonic quantum computing, including direct compatibility with communication, are apparent, several imperfections such as loss and distinguishability prese…
Ultrafast phonon-mediated dephasing of color centers in hexagonal boron nitride probed by electron beams
Masoud Taleb, Paul Bittorf, Mximilian Black +7
Defect centers in hexagonal boron nitride have been extensively studied as room temperature single photon sources. The electronic structure of these defects exhibits strong couplin…
Distributed Partial Quantum Consensus of Qubit Networks with Connected Topologies
Xin Jin, Zhu Cao, Yang Tang +1
In this paper, we consider the partial quantum consensus problem of a qubit network in a distributed view. The local quantum operation is designed based on the Hamiltonian by using…
Particle detectors under chronological hazard
Ana Alonso-Serrano, Erickson Tjoa, Luis J. Garay +1
We analyze how the presence of closed timelike curves (CTCs) characterizing a time machine can be discerned by placing a local particle detector in a region of spacetime which is c…
Symmetry breaking in geometric quantum machine learning in the presence of noise
Cenk Tüysüz, Su Yeon Chang, Maria Demidik +3
Geometric quantum machine learning based on equivariant quantum neural networks (EQNN) recently appeared as a promising direction in quantum machine learning. Despite the encouragi…
