Accelerating Transpilation in Quantum Machine Learning with Haiqu's Rivet-transpiler
Aleksander Kaczmarek, Dikshant Dulal·Aug 29, 2025
Transpilation is a crucial process in preparing quantum circuits for execution on hardware, transforming virtual gates to match device-specific topology by introducing swap gates and basis gates, and applying optimizations that reduce circuit depth a...
Quantum Telegraph Behavior Without Photons
Truong-Son P. Van, Daniel Maienshein, David W. Snoke·Aug 28, 2025
We show that a simple model of non-Hermitian noise gives rise to the telegraph switching behavior seen in experiments with single qubits, without any reference to the existence of photons as corpuscles. This lends support to a continuous collapse int...
Multimode rotationally symmetric bosonic codes from group-theoretic construction
Rabsan Galib Ahmed, Adithi Udupa, Giulia Ferrini·Aug 28, 2025
We introduce a new family of multi-mode, rotationally symmetric bosonic codes inspired by the group-theoretic framework of [Phys. Rev. Lett. 133, 240603 (2024)]. Such a construction inverts the traditional paradigm of code design by identifying codes...

Runshi Zhou, Fang Zhang, Hui-Hai Zhao +3 more·Aug 28, 2025
Generalized bicycle codes (GB codes) represent a promising family of quantum low-density parity-check codes, characterized by high code rates and relatively local qubit connectivity. A subclass of the GB code called bivariate bicycle codes (BB codes)...
Compilation-informed probabilistic logical-error cancellation
Giancarlo Camilo, Thiago O. Maciel, Allan Tosta +4 more·Aug 27, 2025
The potential of quantum computers to outperform classical ones in practically useful tasks remains challenging in the near term due to scaling limitations and high error rates of current quantum hardware. While quantum error correction (QEC) offers ...
Resolving Microscopic Correlated Electron Dynamics via 2000-Qubit Quantum Simulation
Jaka Vodeb·Aug 27, 2025
Understanding how quantum materials return to equilibrium after being driven into excited states is a fundamental problem in condensed matter physics. A prototypical material, 1T-TaS$_2$, exhibits complex electronic textures made up of domain walls, ...
Classical Simulations of Low Magic Quantum Dynamics
Kemal Aziz, Haining Pan, M. Gullans +1 more·Aug 27, 2025
We develop classical simulation algorithms for adaptive quantum circuits that produce states with low levels of ``magic''(i.e., non-stabilizerness). These algorithms are particularly well-suited to circuits with high rates of Pauli measurements, such...
Enhanced algorithmic perfect state transfer on IBM quantum computers
Zong-Yuan Ge, Lian-Ao Wu, Zhao-Ming Wang·Aug 26, 2025
Perfect state transfer (PST) through a spin chain can be theoretically obtained via predesigned PST couplings. We perform the algorithmic PST simulations through short spin chains on IBM quantum computers, alongside Qiskit simulations. The results de...
