Exploiting Movable Logical Qubits for Lattice Surgery Compilation
Laura S. Herzog, Lucas Berent, Aleksander Kubica +1 more·Dec 3, 2025
Lattice surgery with two-dimensional quantum error correcting codes is among the leading schemes for fault-tolerant quantum computation, motivated by superconducting hardware architectures. In conventional lattice surgery compilation schemes, logical...
TARA Test-by-Adaptive-Ranks for Quantum Anomaly Detection with Conformal Prediction Guarantees
Davut Emre Tasar, Ceren Ocal Tasar·Dec 3, 2025
Quantum key distribution (QKD) security fundamentally relies on the ability to distinguish genuine quantum correlations from classical eavesdropper simulations, yet existing certification methods lack rigorous statistical guarantees under finite-samp...
Second-quantized numerical simulations of tunable entanglement in quantum high harmonic generation
Sebastián de-la-Peña, Heiko Appel, Angel Rubio +1 more·Dec 3, 2025
Quantum high-harmonic generation (HHG) is a prominent and growing field of research with potential capabilities of providing high photon-number entangled states of light. However, there is an open debate regarding the theory level required for correc...
Modelling the Impact of Device Imperfections on Electron Shuttling in SiMOS devices
Jack J. Turner, Christian W. Binder, Guido Burkard +1 more·Dec 3, 2025
Extensive theoretical and experimental work has established high-fidelity electron shuttling in Si/SiGe systems, whereas demonstrations in Si/SiO2 (SiMOS) remain at an early stage. To help address this, we perform full 3D simulations of conveyor-belt...
Quantum Simulations of Opinion Dynamics
Xingyu Guo, Xiaoyang Wang, Lingxiao Wang·Dec 3, 2025
Consensus formation is a central problem in collective behavior. In this work, we develop quantum models of opinion dynamics that can be exactly solved and implemented on current quantum hardware. By exploiting quantum superposition, measurement-indu...
An end-to-end quantum algorithm for nonlinear fluid dynamics with bounded quantum advantage
David Jennings, Kamil Korzekwa, Matteo Lostaglio +3 more·Dec 3, 2025
Computational fluid dynamics (CFD) is a cornerstone of classical scientific computing, and there is growing interest in whether quantum computers can accelerate such simulations. To date, the existing proposals for fault-tolerant quantum algorithms f...
Non-Gaussian Dissipative Quantum Thermometry Beyond Gaussian Bounds
Pritam Chattopadhyay·Dec 3, 2025
The fundamental metrological limits of temperature sensing in open quantum systems remain largely unresolved, particularly regarding the role of non-Gaussian quantum resources. In this letter, we establish analytic bounds on the quantum Fisher inform...
Sympathetic Cooling of Levitated Optomechanics through Nonreciprocal Coupling
Jialin Li, Guangyu Zhang, Zhang-qi Yin·Dec 3, 2025
Optomechanical cooling of levitated nanoparticles has become an essential topic in modern quantum physics, providing a platform for exploring macroscopic quantum phenomena and high-precision sensing. However, conventional cavity-assisted cooling is f...

Jan A. P. Reuter, Juhi Singh, Tommaso Calarco +2 more·Dec 3, 2025
Ultracold neutral atoms in optical lattices are a promising platform for simulating the behavior of complex materials and implementing quantum gates. We optimize collision gates for fermionic Lithium atoms confined in a double-well potential, control...
