Amplitude-amplified coherence detection and estimation
Rhea Alexander, Michalis Skotiniotis, Daniel Manzano·Dec 17, 2025
The detection and characterization of quantum coherence is of fundamental importance both in the foundations of quantum theory as well as for the rapidly developing field of quantum technologies, where coherence has been linked to quantum advantage. ...
Bosonic quantum computing with near-term devices and beyond
Timo Hillmann·Dec 17, 2025
(Abridged.) This thesis investigates scalable fault-tolerant quantum computation through the development of bosonic quantum codes, quantum LDPC codes, and decoding protocols that connect continuous-variable and discrete-variable error correction. We ...
Microscopic model for a spatial multimode generation based on Multi-pump Four Wave Mixing in hot vapours
H. M. Florez·Dec 17, 2025
Multipartite entanglement is an important resource for quantum information processing. It has been shown that it is possible to employ alkali atoms to implement single device multipartite entanglement by using nonlinear processes with spatial modes. ...
Noise-Induced Thermalization in Quantum Systems
Sameer Dambal, Yu Zhang, Eric R Bittner +1 more·Dec 16, 2025
In the current Noisy Intermediate-Scale Quantum era, noise is widely regarded as the primary obstacle to achieving fault-tolerant quantum computation. However, certain stages of the quantum computing pipeline can, in fact, benefit from this noise. In...
Symmetric Dicke States as Optimal Probes for Wave-Like Dark Matter
Ping He, Jing Shu, Bin Xu +1 more·Dec 16, 2025
We identify symmetric Dicke states as the optimal quantum probes for distributed sensing of wave-like dark-matter fields. Within an ensemble-averaged quantum-metrological framework that incorporates the field's random phases and finite coherence, the...
Physics-Informed Neural Networks with Adaptive Constraints for Multi-Qubit Quantum Tomography
Changchun Feng, Laifa Tao, Lin Chen·Dec 16, 2025
Quantum state tomography (QST) faces exponential measurement requirements and noise sensitivity in multi-qubit systems, bottlenecking practical quantum technologies. We present a physics-informed neural network (PINN) framework integrating quantum me...
A Graph-Based Forensic Framework for Inferring Hardware Noise of Cloud Quantum Backend
Subrata Das, Archisman Ghosh, Swaroop Ghosh·Dec 16, 2025
Cloud quantum platforms give users access to many backends with different qubit technologies, coupling layouts, and noise levels. The execution of a circuit, however, depends on internal allocation and routing policies that are not observable to the ...
Finite-Time Protocols Stabilize Charging in Noisy Ising Quantum Batteries
Riccardo Grazi, Henrik Johannesson, Dario Ferraro +1 more·Dec 16, 2025
Reliable charging protocols are crucial for advancing quantum batteries toward practical use. We investigate a transverse-field Ising chain as a quantum battery, focusing on the combined role of qubit interactions in the battery model and finite char...
Large circuit execution for NMR spectroscopy simulation on NISQ quantum hardware
Artemiy Burov, Julien Baglio, Clément Javerzac-Galy·Dec 16, 2025
With the latest advances in quantum computing technology, we are gradually moving from the noisy intermediate-scale quantum (NISQ) era characterized by hardware limited in the number of qubits and plagued with quantum noise, to the age of quantum uti...
Graphene-Insulator-Superconductor junctions as thermoelectric bolometers
Leonardo Lucchesi, Federico Paolucci·Dec 16, 2025
We design a superconducting thermoelectric bolometer made of a Graphene-Insulator-Superconductor tunnel junction. Our detector has the advantage of being passive, as it directly transduces input power to a voltage without the need to modulate an exte...
Ground State Energy via Adiabatic Evolution and Phase Measurement for a Molecular Hamiltonian on an Ion-Trap Quantum Computer
Ludwig Nützel, Michael J. Hartmann, Henrik Dreyer +1 more·Dec 16, 2025
Estimating molecular ground-state energies is a central application of quantum computing, requiring both the preparation of accurate quantum states and efficient energy readout. Understanding the effect of hardware noise on these experiments is cruci...
Hybrid acousto-optical spin control in quantum dots
Mateusz Kuniej, Paweł Machnikowski, Michał Gawełczyk·Dec 16, 2025
Mechanical degrees of freedom very weakly couple to spins in semiconductors. The inefficient coupling between phonons and single electron spins in semiconductor quantum dots (QDs) hinders their integration into on-chip acoustically coupled quantum hy...
A nonlinear quantum neural network framework for entanglement engineering
Adriano Macarone-Palmieri, Alberto Ferrara, Rosario Lo Franco·Dec 16, 2025
Multipartite entanglement is a crucial resource for quantum technologies; however, its scalable generation in noisy quantum devices remains a significant challenge. Here, we propose a low-depth quantum neural network architecture with linear scaling,...
Coherence-Sensitive Readout Models for Quantum Devices: Beyond the Classical Assignment Matrix
Zachariah Malik, Zain Saleem·Dec 15, 2025
Readout error models for noisy quantum devices almost universally assume that measurement noise is classical: the measurement statistics are obtained from the ideal computational-basis populations by a column-stochastic assignment matrix $A$. This de...
Group-Theoretic Reinforcement Learning of Dynamical Decoupling Sequences
Charles Marrder, Shuo Sun, Murray J. Holland·Dec 15, 2025
Dynamical decoupling seeks to mitigate phase decoherence in qubits by applying a carefully designed sequence of effectively instantaneous electromagnetic pulses. Although analytic solutions exist for pulse timings that are optimal under specific nois...
Decoding 3D color codes with boundaries
