To Catch and Reverse a Quantum Jump Mid-Flight
Recounts the history of quantum jumps from Bohr to single-ion experiments and the quantum-trajectory prediction that a jump, once begun, follows a coherent and predictable path. It then describes a circuit QED realization of a three-level V-system whose bright level is monitored with about 90% efficiency, the catch protocol, mid-flight tomography, and feedback that reverses the jump. Backup slides cover quantum trajectory theory, dispersive readout issues and the EPR design method.
- Quantum jumps in atoms and ions, and the no-click trajectory that reveals jump coherence
- cQED V-system with bright and dark transmon transitions read out through a cavity
- Catching jumps mid-flight and reversing them with real-time feedback
- Backup: stochastic master equation picture, dispersive readout trade-offs, energy-participation ratio (EPR) design
Summary and key points drafted by a language model from the slides, not yet reviewed by me. The slides are the source.
