High-Fidelity Transmon Reset with a Multimode Acoustic Resonator
arXiv:2604.08655v1 Announce Type: new Abstract: Achieving sufficiently low residual excited-state populations remains a key challenge in superconducting quantum circuits, particularly for protocols operating close to noise limits or requiring repeated qubit initialization. Existing protocols primar…

Every Little Thing Heat Does Is Magic
arXiv:2604.08663v1 Announce Type: new Abstract: How can one certify that an unknown quantum state possesses magic without resorting to full state tomography? We address this question by introducing two thermodynamic witnesses that rely solely on energy and heat measurements. First, we define the st…

Hardware-Efficient Erasure Qubits With Superconducting Transmon Qutrits
arXiv:2604.08672v1 Announce Type: new Abstract: Quantum error correction using erasure qubits offers higher fault-tolerant thresholds and improved scaling by converting dominant physical errors into detectable erasures. In superconducting circuits, erasure qubits can be constructed using the dual-r…
