Policy Gradient Approach to Compilation of Variational Quantum Circuits
David A. Herrera-Martí
We propose a method for finding approximate compilations of quantum unitary transformations, based on techniques from policy gradient reinforcement learning. The choice of a stocha…
Thermodynamics of Optical Bloch Equations
Cyril Elouard, David Herrera-Martí, Massimiliano Esposito +1
Optical Bloch Equations (OBE) describe the coherent exchange of energy between a quantum bit (qubit) and a quasi-resonant driving field in the presence of a thermal bath. Despite i…
Extracting work from quantum measurement in Maxwell demon engines
Cyril Elouard, David Herrera-Martí, Benjamin Huard +1
The essence of both classical and quantum engines is to extract useful energy (work) from stochastic energy sources, e.g. thermal baths. In Maxwell's demon engines, work extraction…
Parameter estimation with efficient photodetectors
Tuvia Gefen, David A. Herrera-Martí, Alex Retzker
Current parameter estimation techniques rely on photodetectors which have low brightness and thus are based on gathering averaged statistics. Recently it was claimed that perfect p…
Tradeoff between Leakage and Dephasing Errors in the Fluxonium Qubit
David A. Herrera-Martí, Ahsan Nazir, Sean D. Barrett
We present a tradeoff between leakage and pure dephasing errors for the fluxonium circuit. We show that in the insulating regime, i.e., when the persistent current flowing across t…
A Photonic Implementation for the Topological Cluster State Quantum Computer
David A. Herrera-Martí, Austin G. Fowler, David Jennings +1
A new implementation of the topological cluster state quantum computer is suggested, in which the basic elements are linear optics, measurements, and a two-dimensional array of qua…
