Catalytic Quantum Error Correction: Theory, Efficient Catalyst Preparation, and Numerical Benchmarks
Hikaru Wakaura·Mar 26, 2026
We introduce Catalytic Quantum Error Correction (CQEC), a state recovery protocol exploiting catalytic covariant transformations. CQEC recovers a known target state from noisy copies without an error \emph{magnitude} threshold: recovery succeeds when...

Quantum Spectral Authentication under Public Unitary Challenges
S. P. Kish, H. J. Vallury, J. Pieprzyk +2 more·Mar 25, 2026
We introduce Quantum Spectral Authentication (QSA), a primitive for verifying that a remote quantum endpoint still possesses a previously installed secret quantum resource, such as a hidden state or state-preparation capability, without revealing tha...
Quantum Magnetometers for Infrastructure Inspection and Monitoring
Muhammad Mahmudul Hasan, Ingrid Torres, Alex Krasnok·Mar 25, 2026
Damage in infrastructure is often hidden until it becomes costly or dangerous. Common examples include corrosion under insulation, early fatigue damage in steel, corrosion of embedded reinforcement, and abnormal current flow in batteries and power eq...
Decoder Dependence in Surface-Code Threshold Estimation with Native Gottesman-Kitaev-Preskill Digitization and Parallelized Sampling
Dennis Delali Kwesi Wayo, Chinonso Onah, Leonardo Goliatt +1 more·Mar 25, 2026
We quantify decoder dependence in surface-code threshold studies under two matched regimes: Pauli noise and native GKP-style Gaussian displacement digitization. Using LiDMaS+ v1.1.0, we benchmark MWPM, Union-Find (UF), Belief Propagation (BP), and ne...
Wavefunction Collapse in String Theory
Nissan Itzhaki·Mar 25, 2026
One of the most intriguing proposals for wavefunction collapse is the Diosi Penrose model, in which collapse is driven by stochastic fluctuations of the Newtonian potential. We argue that a closely related effective structure can emerge in string the...
Robust Parametric Quantum Gate Against Stochastic Time-Varying Noise
Yang He, Zigui Zhang, Zibo Miao·Mar 25, 2026
The performance of quantum processors in the noisy intermediate-scale quantum (NISQ) era is severely constrained by environmental noise and other uncertainties. While the recently proposed quantum control robustness landscape (QCRL) offers a powerful...
Correlated Atom Loss as a Resource for Quantum Error Correction
Hugo Perrin, Gatien Roger, Guido Pupillo·Mar 25, 2026
Atom loss is a dominant error source in neutral-atom quantum processors, yet its correlated structure remains largely unexploited by existing quantum error correction decoders. We analyze the performance of the surface code equipped with teleportatio...

Quantum computers, currently in the noisy intermediate-scale quantum (NISQ) era, have started to provide scientists with a novel tool to explore quantum physics and chemistry. While several electronic systems have been extensively studied, Frenkel ex...
Precision bounds for frequency estimation under collective dephasing and open-loop control
Francisco Riberi, Gerardo Paz-Silva, Lorenza Viola·Mar 25, 2026
Dephasing noise is a ubiquitous source of decoherence in current atomic sensors. We address the problem of entanglement-assisted frequency estimation subject to classical dephasing noise with full spatial correlations (collective) and arbitrary tempo...

Fluxonium superconducting qubits have demonstrated long coherence times and high single- and two-qubit gate fidelities, making them a favorable building block for superconducting quantum processors. We investigate the dominant limitations to fluxoniu...
Optimal pure state cloning and transposition are complementary channels
Vanessa Brzić, Dmitry Grinko, Michał Studziński +1 more·Mar 24, 2026
State cloning and state transposition are fundamental transformations which, despite being desirable, cannot be perfectly realised due to two conceptually distinct constraints of quantum theory: cloning is forbidden by linearity, while transposition ...
