Continuous measurements for control of superconducting quantum circuits
Shay Hacohen-Gourgy, Leigh S. Martin
Developments over the last two decades have opened the path towards quantum technologies in many quantum systems, such as cold atoms, trapped ions, cavity-quantum electrodynamics (…
Quantum proportional-integral (PI) control
Hui Chen, Hanhan Li, Felix Motzoi +3
Feedback control is an essential component of many modern technologies and provides a key capability for emergent quantum technologies. We extend existing approaches of direct feed…
Quantum feedback for measurement and control
Leigh S. Martin
The standard quantum formalism introduced at the undergraduate level treats measurement as an instantaneous collapse. In reality however, no physical process can occur over a truly…
Single-shot deterministic entanglement between non-interacting systems with linear optics
Leigh S. Martin, K. Birgitta Whaley
Measurement-based heralded entanglement schemes have served as the primary link between physically separated qubits in most quantum information platforms. However, the impossibilit…
Optimality of feedback control for qubit purification under inefficient measurement
Yuxiao Jiang, Xiyue Wang, Leigh Martin +1
A quantum system may be purified, i.e., projected into a pure state, faster if one applies feedback operations during the measurement process. However existing results suggest that…
Using a Recurrent Neural Network to Reconstruct Quantum Dynamics of a Superconducting Qubit from Physical Observations
Emmanuel Flurin, Leigh S. Martin, Shay Hacohen-Gourgy +1
At its core, Quantum Mechanics is a theory developed to describe fundamental observations in the spectroscopy of solids and gases. Despite these practical roots, however, quantum t…
