Recent quantum runtime (dis)advantages
J. Tuziemski, J. Pawłowski, P. Tarasiuk +2
A robust definition of quantum runtime is essential for assessing the performance of quantum algorithms and claims of quantum advantage. While for most classical hardware the total…
Bosonic content of three-fermion highest-spin states
Jerzy Cioslowski, Krzysztof Strasburger, Denis K. Sunko
A rigorous characterization of the information content of any highest-spin three-fermion wave function is presented. It is based upon a formal decomposition of the wave function in…

J. Pawłowski, P. Tarasiuk, J. Tuziemski +2
In a recent Letter [H. Munoz-Bauza and D. Lidar, Phys. Rev. Lett. 134, 160601 (2025)], quantum annealing was reported to exhibit a scaling advantage in approximately solving quadra…
A Fiber-pigtailed Quantum Dot Device Generating Indistinguishable Photons at GHz Clock-rates
Lucas Rickert, Kinga Żołnacz, Daniel A. Vajner +11
Solid-state quantum light sources based on semiconductor quantum dots (QDs) are increasingly employed in photonic quantum information applications. Especially when moving towards r…
Laser-written waveguide-integrated coherent spins in diamond

Quantum emitters, such as the negatively charged nitrogen-vacancy center in diamond, are attractive for quantum technologies such as nano-sensing, quantum information processing, a…
Measures of distance in quantum mechanics
P. Gusin, D. Burys, A. Radosz
Combining gravity with quantum theory is still work in progress. On the one hand, classical gravity, is the geometry of space-time determined by the energy-momentum tensor of matte…
Estimation of nuclear polarization via discrete measurement of NV center spin evolution

Daniel Groll, Fabian Paschen, Paweł Machnikowski +3
In today's development of quantum technologies a hybrid integration of phononic excitations becomes increasingly attractive. As natural quasi-particle excitations in solid state sy…
