Limits of heralded photonic Bell-state generation in the presence of loss
Kevin J. Randles, Manuel H. Muñoz-Arias, Mohan Sarovar
High-quality entangled states of photons underlie quantum information science (QIS) applications across communication, sensing, and computing. In many discrete-variable photonic QI…
Measurement-induced state transitions in multi-qubit transmon processors
Baptiste Hoyau, Alexander McDonald, Boris M. Varbanov +2
Dispersive readout of the transmon qubit in circuit QED is known to lose its quantum non-demolition character at small to moderate measurement drive amplitudes. This phenomenon is…
Data-driven learning of non-Markovian quantum dynamics
Samuel Goodwin, Brian K. McFarland, Manuel H. Muñoz-Arias +6
Fault-tolerant quantum computing requires extremely precise knowledge and control of qubit dynamics during the application of a gate. We develop a data-driven learning protocol for…
Modeling integrated frequency shifters and beam splitters
Manuel H. Muñoz-Arias, Manuel H. Muñoz-Arias, Kevin J. Randles +4
Photonic quantum computing is a strong contender in the race to fault-tolerance. Recent proposals using qubits encoded in frequency modes promise a large reduction in hardware foot…
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…
