Device Independent Quantum Secret Sharing Using Multiparty Pseudo-telepathy Game
Santanu Majhi, Goutam Paul·Dec 10, 2025
Device-independent quantum secret sharing (DI-QSS) provides security against untrusted quantum devices. While device-independent quantum key distribution (DI-QKD) using Mermin-Peres magic square game [Zhen et al., Phys. Rev. Lett, 2023] has been prop...
Pattern Based Quantum Key Distribution using the five qubit perfect code for eavesdropper detection
Mehedi Hasan Rumi·Dec 10, 2025
I propose a new quantum key distribution protocol that uses the five qubit error correction code to detect the presence of eavesdropper reliably. The protocol turns any information theoretical attacks into a classical guess about the pattern. The log...
Graph-Based Bayesian Optimization for Quantum Circuit Architecture Search with Uncertainty Calibrated Surrogates
Prashant Kumar Choudhary, Nouhaila Innan, Muhammad Shafique +1 more·Dec 10, 2025
Quantum circuit design is a key bottleneck for practical quantum machine learning on complex, real-world data. We present an automated framework that discovers and refines variational quantum circuits (VQCs) using graph-based Bayesian optimization wi...
Exact and Efficient Stabilizer Simulation of Thermal-Relaxation Noise for Quantum Error Correction
Sean R. Garner, Nathan M. Myers, Meng Wang +3 more·Dec 9, 2025
Stabilizer-based simulation of quantum error-correcting codes typically relies on the Pauli-twirling approximation (PTA) to render non-Clifford noise classically tractable, but PTA can distort the behavior of physically relevant channels such as ther...
SAQ: Stabilizer-Aware Quantum Error Correction Decoder
David Zenati, Eliya Nachmani·Dec 9, 2025
Quantum Error Correction (QEC) decoding faces a fundamental accuracy-efficiency tradeoff. Classical methods like Minimum Weight Perfect Matching (MWPM) exhibit variable performance across noise models and suffer from polynomial complexity, while tens...
Emergent Non-Markovianity in Logical Qubit Dynamics
Jalan A. Ziyad, Robin Blume-Kohout, Kenneth Rudinger·Dec 9, 2025
Logical qubits encoded in quantum error correcting codes can exhibit non-Markovian dynamical evolution, even when the underlying physical noise is Markovian. To understand this emergent non-Markovianity, we define a Markovianity condition appropriate...
Spectroscopic readout of chiral photonic topology in a single-cavity spin-orbit-coupled Bose-Einstein condensate
Kashif Ammar Yasir, Gao Xianlong·Dec 9, 2025
Topological photonic phases are typically identified through band reconstruction, steady-state transmission, or real-space imaging of edge modes. In this work, we present a framework for spectroscopic readout of chiral photonic topology in a single d...
Strain sensitivity enhancement in a Grover-Michelson interferometer
Anthony D. Manni, Christopher R. Schwarze, David S. Simon +2 more·Dec 9, 2025
The Michelson interferometric phase detection resolution can be enhanced by replacing conventional beam splitters with novel directionally unbiased four-port scatterers, such as Grover coins. We present a quantitative analysis of the noise-to-signal ...
Deterministic Quantum Communication Between Fixed-Frequency Superconducting Qubits via Broadband Resonators
Takeaki Miyamura, Zhiling Wang, Kohei Matsuura +5 more·Dec 9, 2025
Quantum communication between remote chips is essential for realizing large-scale superconducting quantum computers. For such communication, itinerant microwave photons propagating through transmission lines offer a promising approach. However, demon...
The utility of noiseless linear amplification and attenuation in single-rail discrete-variable quantum communications
Ozlem Erkilic, Aritra Das, Angela A. Baiju +3 more·Dec 9, 2025
Quantum communication offers many applications, with teleportation and superdense coding being two of the most fundamental. In these protocols, pre-shared entanglement enables either the faithful transfer of quantum states or the transmission of more...

We present a theoretical investigation of ion-induced Coulomb explosion imaging (CEI) of pyridazine molecules driven by energetic C$^{5+}$ projectiles, using time-dependent density-functional theory (TDDFT) with Ehrenfest nuclear dynamics. By systema...
Comparing quantum channels using Hermitian-preserving trace-preserving linear maps: A physically meaningful approach
Arindam Mitra, Jatin Ghai·Dec 8, 2025
In quantum technologies, quantum channels are essential elements for the transmission of quantum states. The action of a quantum channel usually introduces noise in the quantum state and thereby reduces the information contained in it. These are math...

Andrew W. Senior, Thomas Edlich, Francisco J. H. Heras +21 more·Dec 8, 2025
Fault-tolerant quantum computing will require error rates far below those achievable with physical qubits. Quantum error correction (QEC) bridges this gap, but depends on decoders being simultaneously fast, accurate, and scalable. This combination of...
