Robustness of longitudinal transmon readout to ionization
Alex A. Chapple, Alexander McDonald, Manuel H. Muñoz-Arias +1
Multi-photon processes deteriorate the quantum non-demolition (QND) character of the dispersive readout in circuit QED, causing readout to lag behind single and two-qubit gates, in…
Quantum ergodicity and scrambling in quantum annealers
Manuel H. Muñoz-Arias, Pablo M. Poggi
Quantum annealers play a major role in the ongoing development of quantum information processing and in the advent of quantum technologies. Their functioning is underpinned by the…
Deterministic generation of a 20-qubit two-dimensional photonic cluster state
James O'Sullivan, Kevin Reuer, Aleksandr Grigorev +11
Multidimensional cluster states are a key resource for robust quantum communication, measurement-based quantum computing and quantum metrology. Here, we present a device capable of…
Measurement-Induced Transmon Ionization
Marie Frédérique Dumas, Benjamin Groleau-Paré, Alexander McDonald +4
Despite the high measurement fidelity that can now be reached, the dispersive qubit readout of circuit quantum electrodynamics is plagued by a loss of its quantum nondemolition cha…
