Enabling full localization of qubits and gates with a multi-mode coupler
Zhongyi Jiang, Simon Geisert, Sören Ihssen +2
Tunable couplers are a key building block of superconducting quantum processors, enabling high on-off ratios for two-qubit entangling interactions. While qubit-qubit interaction ca…

Information Transport in Classical-Quantum Hybrid System
Julian Rapp, Radhika H. Joshi, Alwin van Steensel +2
Many important quantities in quantum information science, such as entropy and entanglement, are non-linear functions of the density matrix and cannot be expressed as operator obser…

Concurrent Fermionic Simulation Gate
Zhongyi Jiang, Mohammad H. Ansari
Introducing flexible native entanglement gates can significantly reduce circuit complexity. We propose a novel gate integrating iswap and cphase operations within a single gate cyc…
