Revealing effects of local dimension on variable-range interacting model by connecting Lieb-Robinson bounds and multipartite entanglement
Keshav Das Agarwal, Debkanta Ghosh, Pritam Halder +1 more·Nov 14, 2023
A spin-$s$ variable-range interacting Ising model may display qualitatively different behaviors depending on the fall-off rate of the interactions, as already seen in equilibrium studies of spin-1/2 systems. We propose a dynamical method using weight...
QuantumEyes: Towards Better Interpretability of Quantum Circuits
Shaolun Ruan, Qian-Guo Guan, Paul Griffin +2 more·Nov 14, 2023
Quantum computing offers significant speedup compared to classical computing, which has led to a growing interest among users in learning and applying quantum computing across various applications. However, quantum circuits, which are fundamental for...
Zeno-effect computation: Opportunities and challenges
Jesse Berwald, Nicholas Chancellor, Raouf Dridi·Nov 14, 2023
Adiabatic quantum computing has demonstrated how quantum Zeno can be used to construct quantum optimisers. However, much less work has been done to understand how more general Zeno effects could be used in a similar setting. We use a construction bas...
High-efficiency single-photon source above the loss-tolerant threshold for efficient linear optical quantum computing
X. Ding, Yong-Peng Guo, Mo-Chi Xu +13 more·Nov 14, 2023
Photon loss is the biggest problem for scalable photonic quantum information processing. This issue can be tackled through quantum error correction, provided that the overall photon loss is below a threshold of one-third. However, all reported on-dem...
Circuit-noise-resilient virtual distillation
Xiao-Yue Xu, Chen Ding, Shuo Zhang +2 more·Nov 14, 2023
Quantum error mitigation (QEM) is vital for improving quantum algorithms’ accuracy on noisy near-term devices. A typical QEM method, called Virtual Distillation (VD), can suffer from imperfect implementation, potentially leading to worse outcomes tha...
Lecture notes on quantum computing
A. F. Kockum, Ariadna Soro, Laura Garc'ia-'Alvarez +4 more·Nov 14, 2023
These are the lecture notes of the master's course"Quantum Computing", taught at Chalmers University of Technology every fall since 2020, with participation of students from RWTH Aachen and Delft University of Technology. The aim of this course is to...
Hybrid GRU-CNN bilinear parameters initialization for quantum approximate optimization algorithm
Zuyu Xu, Pengnian Cai, Kang Shen +7 more·Nov 14, 2023
The Quantum Approximate Optimization Algorithm (QAOA), a pivotal paradigm in the realm of variational quantum algorithms (VQAs), offers promising computational advantages for tackling combinatorial optimization problems. Well-defined initial circuit ...
"Nonlocality-of-a-single-photon" based Quantum Key Distribution and Random Number Generation schemes and their device-independent security analysis
Konrad Schlichtholz, Bianka Woloncewicz, Tamoghna Das +2 more·Nov 13, 2023
The question of ``non-locality of a single photon'', which started with a paper by Tan, Walls and Collett (TWC, 1991) stirred a thirty years long debate. This hampered attempts to use the TWC interferometric scheme in quantum cryptography. The scheme...
Optical Nanofiber Testbeds for Benchmarking Membrane-Waveguide Photonic Integrated Circuit Platforms toward On-Chip Quantum Inertial Sensing
Adrian Orozco, William Kindel, Nicholas Karl +4 more·Nov 13, 2023
Recent advances in cold atom interferometry with optical and magnetic atom guides have set the stage for quantum inertial sensors capable of operating in dynamic environments. In this work, we present three key innovations, such as evanescent-field (...

Y. Kurman, Lior Ella, Ramon Szmuk +4 more·Nov 13, 2023
Reaching fault-tolerant quantum computation relies on the successful implementation of non-Clifford circuits with quantum error correction (QEC). In QEC, quantum gates and measurements encode quantum information into an error-protected Hilbert space,...
