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...
Quantum computing on encrypted data with arbitrary rotation gates
Mohit Joshi, Manoj Kumar Mishra, S. Karthikeyan·Aug 26, 2025
An efficient technique of computing on encrypted data allows a client with limited capability to perform complex operations on a remote fault-tolerant server without leaking anything about the input or output. Quantum computing provides information-t...
First-Quantized Quantum Simulation of Non-Relativistic QED with Emergent Topologically Protected Coulomb Interactions
Torin F. Stetina, Nathan Wiebe·Aug 26, 2025
We provide a simulation algorithm that properly addresses light matter interaction between non-relativistic first-quantized charged particles and quantum electromagnetic fields. Unlike previous work, our Hamiltonian does not include an explicit Coulo...

Quantum computers represent a radical technological advancement in the way information is processed by using the principles of quantum mechanics to solve very complex problems that exceed the capabilities of classical systems. However, in the current...
Robust Control and Entanglement of Qudits in Neutral Atom Arrays
Amir Burshtein, Shachar Fraenkel, Moshe Goldstein +1 more·Aug 22, 2025
Quantum devices comprised of elementary components with more than two stable levels - so-called qudits - enrich the accessible Hilbert space, enabling applications ranging from fault-tolerant quantum computing to simulating complex many-body models. ...
Above 99.9% Fidelity Single-Qubit Gates, Two-Qubit Gates, and Readout in a Single Superconducting Quantum Device
F. Marxer, Jakub Mro.zek, J. Andersson +64 more·Aug 22, 2025
Achieving high-fidelity single-qubit gates, two-qubit gates, and qubit readout is critical for building scalable, error-corrected quantum computers. However, device parameters that enhance one operation often degrade the others, making simultaneous o...
Quantum Optimal Control with Geodesic Pulse Engineering
D. Lewis, R. Wiersema, Sougato Bose·Aug 22, 2025
Designing multi-qubit quantum logic gates with experimental constraints is an important problem in quantum computing. Here, we develop a new quantum optimal control algorithm for finding unitary transformations with constraints on the Hamiltonian. Th...
