Demonstration of measurement-free universal fault-tolerant quantum computation
Friederike Butt, Ivan Pogorelov, R. Freund +4 more·Jun 27, 2025
The ability to perform quantum error correction (QEC) and robust gate operations on encoded qubits opens the door to demonstrations of quantum algorithms. Contemporary QEC schemes typically require mid-circuit measurements with feed-forward control, ...
Linearization Scheme of Shallow Water Equations for Quantum Algorithms
Till Appel, Zofia Binczyk, Francesco Conoscenti +4 more·Jun 27, 2025

Optimizing continuous-time quantum error correction for arbitrary noise
Anirudh Lanka, Shashank Hegde, Todd A. Brun·Jun 26, 2025
We present a protocol using machine learning (ML) to simultaneously optimize the quantum error-correcting code space and the corresponding recovery map in the framework of continuous-time quantum error correction. Given a Hilbert space and a noise pr...
Quantum thermal state preparation for near-term quantum processors
Jerome Lloyd, Dmitry A. Abanin·Jun 26, 2025
Preparation of quantum thermal states of many-body systems is a key computational challenge for quantum processors, with applications in physics, chemistry, and classical optimization. We provide a simple and efficient algorithm for thermal state pre...
Meson spectroscopy of exotic symmetries of Ising criticality in Rydberg atom arrays
Joseph Vovrosh, Julius de Hond, Sergi Julià-Farré +2 more·Jun 26, 2025
The Ising model serves as a canonical platform for exploring emergent symmetry in quantum critical systems. The critical point of the 1D Ising chain is described by a conformal Ising field theory, which remains integrable in the presence of a magneti...
Disentangling tensor product structures
Antoine Soulas·Jun 26, 2025
As a contribution to the field of quantum mereology, we study how a change of tensor product structure in a finite-dimensional Hilbert space affects its entanglement properties. In particular, we ask whether, given a time-evolving state, there exists...
Hardware-Aware Quantum Kernel Design Based on Graph Neural Networks
Fanxu Meng, Yuxiang Liu, Lu Wang +3 more·Jun 26, 2025
Quantum kernels hold significant promise for achieving computational advantages in quantum machine learning (QML), yet their effectiveness critically depends on the design of expressive and hardware-compatible feature maps, a challenge that is partic...
Efficient implementation of quantum signal processing via the adiabatic-impulse model
D. O. Shendryk, O. V. Ivakhnenko, S. N. Shevchenko +1 more·Jun 26, 2025
Here we investigate analogy between quantum signal processing (QSP) and the adiabatic-impulse model (AIM) in order to implement the QSP algorithm with fast quantum logic gates. QSP is an algorithm that uses single-qubit dynamics to perform a polynomi...
