Spin-orbit-enabled realization of arbitrary two-qubit gates on moving spins
D. Fern'andez-Fern'andez, Y. Matsumoto, L. Vandersypen +2 more·Aug 11, 2025
Shuttling spin qubits in systems with large spin-orbit interaction (SOI) can cause errors during motion. However, in this work, we demonstrate that SOI can be harnessed to implement an arbitrary high-fidelity two-qubit (2Q) gate. We consider two spin...
A Method for Constructing Quasi-Random Peaked Quantum Circuits
O. G. Udalov·Aug 10, 2025
An algorithm is proposed for constructing quasi-random"peaked"quantum circuits, i.e., circuits whose final qubit state exhibits a high probability concentration on a specific computational basis state. These circuits consist of random gates arranged ...
Enhancing the Scalability of Classical Surrogates for Real-World Quantum Machine Learning Applications
Philip Anton Hernicht, Alona Sakhnenko, Corey O’Meara +2 more·Aug 8, 2025
