Framework for (non-)adiabatic chiral state conversion: from non-Hermitian Hamiltonians to Liouvillians

Elna Svegborn, Shishir Khandelwal·Feb 10, 2026

Adiabatic chiral state conversion (CSC) is one of the many counterintuitive effects associated with non-Hermitian physics. In quantum systems, numerous works have demonstrated this phenomenon under both non-Hermitian Hamiltonian and Lindblad evolutio...

Negative Hybridization: a Potential Cure for Braiding with Imperfect Majorana Modes

Cole Peeters, Themba Hodge, Stephan Rachel·Feb 9, 2026

Majorana zero modes, the elementary building blocks for the quantum bits of topological quantum computers, are known to suffer from hybridization as their wavefunctions begin to overlap. This breaks the ground state degeneracy, splitting their energy...

High-Probability Heralded Entanglement via Repeated Spin-Photon Phase Encoding with Moderate Cooperativity

Yu Liu, Martin B. Plenio·Feb 9, 2026

We propose a heralded high-probability scheme to generate remote entanglement between moderate-cooperativity spin-cavity registers with high fidelity. In conventional single-shot interfaces, limited cooperativity restricts the spin-conditional optica...
