Quantum science with arrays of metastable helium-3 atoms
Zheyuan Li, Rupsa De, Rishi Sivakumar +7 more·Jan 11, 2026
The motion of atoms in programmable optical tweezer arrays offers many new opportunities for neutral atom quantum science. These include inter- and intra-site atom motion for resource-efficient implementations of fermionic and bosonic modes, respecti...
Rydberg atom parity gate based on dark state resonances
Sinchan Snigdha Rej, Snigdhadev Ray, Bimalendu Deb·Jan 10, 2026
Quantum computation (QC) and digital quantum simulation (DQS) essentially require two- or multi-qubit controlled-NOT or -phase gates. We propose an alternative pathway for QC and DQS using a three-qubit parity gate in a Rydberg atom array. The basic ...
Magnetic levitation and spatial superposition of a nanodiamond with a current-carrying chip
Qian Xiang, Shafaq Gulzar Elahi, Andrew Geraci +2 more·Jan 10, 2026
We propose a current-carrying-chip scheme for generating spatial quantum superpositions using a levitating nanodiamond with a built-in nitrogen-vacancy (NV) centre defect. Our setup is quite versatile and we aim to create the superposition for a mass...
Fault-Tolerant Quantum Error Correction: Implementing Hamming-Based Codes with Advanced Syndrome Extraction Techniques
Soham Bhadra, Diyansha Singh, Angana Chowdhury·Jan 10, 2026
Building reliable quantum computers requires protecting fragile quantum states from inevitable environmental noise and operational errors. While quantum error correction codes like the Steane $[\![7,1,3]\!]$ code provide elegant theoretical solutions...
Controlling Rydberg atom-polariton interactions: from exceptional points to fast readout
Tamara Šumarac, Emily H. Qiu, Shai Tsesses +8 more·Jan 9, 2026
Rydberg atoms represent a platform underpinning many recent developments in quantum computation, simulation, sensing, and metrology. They further facilitate optical nonlinearity at the single-photon level when coupled to photons propagating in atomic...
Quantum algorithm for dephasing of coupled systems: decoupling and IQP duality
Sabrina Yue Wang, Raul A. Santos·Jan 9, 2026
Noise and decoherence are ubiquitous in the dynamics of quantum systems coupled to an external environment. In the regime where environmental correlations decay rapidly, the evolution of a subsytem is well described by a Lindblad quantum master equat...
Scaleable LED-pumped Room-temperature Maser using a Multi-blade Optical Injector
Mingyang Liu, Zike Cheng, Ziqiu Huang +3 more·Jan 9, 2026
Though the performance of room-temperature masers has improved over the last decade, relatively little attention has been paid to the optics used to pump the maser's gain medium. In this work, we investigate a novel multi-blade optical ``injector'' t...
Counterdiabatic ADAPT-VQE for molecular simulation
Diego Tancara, Herbert Díaz-Moraga, Dardo Goyeneche·Jan 9, 2026
Among variational quantum algorithms designed for NISQ devices, ADAPT-VQE stands out for its robustness against barren plateaus, particularly in estimating molecular ground states. On the other hand, counterdiabatic algorithms have shown advantages i...
Continuous-time noise mitigation in analogue quantum simulation
Gabriele Bressanini, Yue Ma, Hyukjoon Kwon +1 more·Jan 9, 2026
Analogue quantum simulators offer a promising route to explore quantum many-body dynamics beyond classical reach in the near term. However, their vulnerability to noise limits the accuracy of simulations. Here, we establish a new framework for mitiga...
Universal Dilation of Linear Itô SDEs: Quantum Trajectories and Lindblad Simulation of Second Moments
Hsuan-Cheng Wu, Xiantao Li·Jan 9, 2026
We present a universal framework for simulating $N$-dimensional linear Itô stochastic differential equations (SDEs) on quantum computers with additive or multiplicative noises. Building on a unitary dilation technique, we establish a rigorous mapping...
Dynamical entanglement percolation with spatially correlated disorder
Lorenzo Cirigliano, Valentina Brosco, Claudio Castellano +3 more·Jan 9, 2026
The distribution of entanglement between the nodes of a quantum network plays a fundamental role in quantum information applications. In this work, we investigate the dynamics of a network of qubits where each edge corresponds to an independent two-q...
On the robustness of Quantum Phase Estimation to compute ground properties of many-electron systems
Wassil Sennane, Jérémie Messud·Jan 9, 2026
We propose an analysis of the Quantum Phase Estimation (QPE) algorithm applied to electronic systems by investigating its free parameters such as the time step, number of phase qubits, initial state preparation, number of measurement shots, and param...
Quantum Interference-Induced Bhattacharyya Distance
Mostafizur Rahaman Laskar·Jan 9, 2026
We propose a quantum distance measure between probability distributions encoded in quantum states based on the fragility of quantum interference under entangling evolution. The Quantum Interference-Induced Bhattacharyya Distance (QIBD) is defined thr...
Block Encoding Linear Combinations of Pauli Strings Using the Stabilizer Formalism
Niclas Schillo, Andreas Sturm, Rüdiger Quay·Jan 9, 2026
The Quantum Singular Value Transformation (QSVT) provides a powerful framework with the potential for quantum speedups across a wide range of applications. Its core input model is the block encoding framework, in which non-unitary matrices are embedd...
Feature Entanglement-based Quantum Multimodal Fusion Neural Network
Yu Wu, Qianli Zhou, Jie Geng +2 more·Jan 9, 2026
Multimodal learning aims to enhance perceptual and decision-making capabilities by integrating information from diverse sources. However, classical deep learning approaches face a critical trade-off between the high accuracy of black-box feature-leve...
Scalable Suppression of XY Crosstalk by Pulse-Level Control in Superconducting Quantum Processors
Hui-Hang Chen, Chiao-Hsuan Wang·Jan 8, 2026
As superconducting quantum processors continue to scale, high-performance quantum control becomes increasingly critical. In densely integrated architectures, unwanted interactions between nearby qubits give rise to crosstalk errors that limit operati...
