Lecture Notes on Information Scrambling, Quantum Chaos, and Haar-Random States
Marcin Płodzień·Nov 18, 2025
Information scrambling, the process by which quantum information spreads and becomes effectively inaccessible, is central to modern quantum statistical physics and quantum chaos. These lecture notes provide an introduction to information scrambling f...
Compiler design for hardware specific decomposition optimizations, tailored to diamond NV centers
Folkert de Ronde, Stephan Wong, Sebastian Feld·Nov 18, 2025
Advances in quantum algorithms as well as in control hardware designs are continuously being made. These quantum algorithms, expressed as quantum circuits, need to be translated to a set of instructions from a defined quantum instruction-set architec...
Empirical Quantum Advantage in Constrained Optimization from Encoded Unitary Designs
Chinonso Onah, Roman Firt, Kristel Michielsen·Nov 18, 2025
We introduce the Constraint-Enhanced Quantum Approximate Optimization Algorithm (CE-QAOA), a shallow, constraint-aware ansatz that operates inside the one-hot product space [n]^m, where m is the number of blocks and each block is initialized in an n-...
Entropic uncertainty under indefinite causal order and input-output direction
Göktuğ Karpat·Nov 18, 2025
Entropic uncertainty relations quantify the limits on the predictability of quantum measurements. When the measured system is correlated with a quantum memory, these limits are described by the memory-assisted entropic uncertainty relation (MA-EUR). ...
Architectural Approaches to Fault-Tolerant Distributed Quantum Computing and Their Entanglement Overheads
Nitish Kumar Chandra, Eneet Kaur, Kaushik P. Seshadreesan·Nov 17, 2025
Fault tolerant quantum computation over distributed quantum computing (DQC) platforms requires careful evaluation of resource requirements and noise thresholds. As quantum hardware advances toward modular and networked architectures, various fault to...
Modeling Quantum Noise in Nanolasers using Markov Chains
Matias Bundgaard-Nielsen, Gian Luca Lippi, Jesper Mørk·Nov 17, 2025
The random nature of spontaneous emission leads to unavoidable fluctuations in a laser's output. This is often included through random Langevin forces in laser rate equations, but this approach falls short for nanolasers. In this paper, we show that ...
Density of reflection resonances in one-dimensional disordered Schrödinger operators
Yan V. Fyodorov, Jan Meibohm·Nov 17, 2025
We develop an analytic approach to evaluating the density $ρ({\cal E},Γ)$ of complex resonance poles with real energies $\mathcal{E}$ and widths $Γ$ in the pure reflection problem from a one-dimensional disordered sample with white-noise random poten...
Measurement-based Dynamical Decoupling for Fidelity Preservation on Large-scale Quantum Processors
Jeongwoo Jae, Changwon Lee, Juzar Thingna +2 more·Nov 17, 2025
Dynamical decoupling (DD) is a key technique for suppressing decoherence and preserving the performance of quantum algorithms. We introduce a measurement-based DD (MDD) protocol that determines control unitary gates from partial measurements of noisy...
Taming Barren Plateaus in Arbitrary Parameterized Quantum Circuits without Sacrificing Expressibility
Zhenyu Chen, Yuguo Shao, Zhengwei Liu +1 more·Nov 17, 2025
Quantum algorithms based on parameterized quantum circuits (PQCs) have enabled a wide range of applications on near-term quantum devices. However, existing PQC architectures face several challenges, among which the ``barren plateaus" phenomenon is pa...
Depth optimization of CNOT ladder circuits
Spyros Tserkis, Muhammad Umer, Dimitris G. Angelakis·Nov 17, 2025
The increasing depth of quantum circuits presents a major limitation for the execution of quantum algorithms, as the limited coherence time of physical qubits leads to noise that manifests as errors during computation. In this work, we focus on CNOT ...
Data-driven adaptive quantum error mitigation for probability distribution
Rion Shimazu, Suguru Endo, Shigeo Hakkaku +1 more·Nov 17, 2025
Quantum error mitigation (QEM) has been proposed as a class of hardware-friendly error suppression techniques. While QEM has been primarily studied for mitigating errors in the estimation of expectation values of observables, recent works have explor...
The correlated matching decoder for the 4.8.8 color code
Yantong Liu, Junjie Wu, Lingling Lao·Nov 17, 2025
Color codes present distinct advantages for fault-tolerant quantum computing, such as high encoding rates and the transversal implementation of Clifford gates. However, existing matching-based decoders for the color codes such as the restricted decod...
Hybrid Quantum-Classical Dispatching for High-Renewable Power Systems:A Noise-Resilient Variational Approach with Real-World Validation
Fu Zhang, Yuming Zhao·Nov 17, 2025
This study introduces a hybrid quantum-classical dispatching framework designed for power systems with high renewable penetration. The proposed method integrates a variational quantum algorithm with classical optimization to provide noise-resilient p...
Approximate Message Passing for Quantum State Tomography
Noah Siekierski, Kausthubh Chandramouli, Christian Kümmerle +2 more·Nov 17, 2025
Quantum state tomography (QST) is an indispensable tool for characterizing many-body quantum systems. However, due to the exponential scaling of the cost of the protocol with system size, many approaches have been developed for quantum states with sp...
When does numerical pulse optimization actually help? Error budgets,robustness tradeoffs, and calibration guidance for transmon single-qubit gates
Rylan Malarchick·Nov 16, 2025
Numerical optimal control (GRAPE) can in principle discover pulse shapes that suppress all coherent gate error to machine precision. But when does that capability actually matter? We present a systematic comparison of Gaussian, DRAG, and GRAPE pulses...
