Parameters estimation by fitting correlation functions of continuous quantum measurement
Pierre Guilmin, Pierre Rouchon, Antoine Tilloy
We propose a simple method to estimate the parameters of a continuously measured quantum system, by fitting correlation functions of the measured signal. We demonstrate the approac…
On encoded quantum gate generation by iterative Lyapunov-based methods
Paulo Sergio Pereira da Silva, Pierre Rouchon
The problem of encoded quantum gate generation is studied in this paper. The idea is to consider a quantum system of higher dimension than the dimension of the quantum…
Explicit formulas for adiabatic elimination with fast unitary dynamics
Angela Riva, Alain Sarlette, Pierre Rouchon
The so-called ``adiabatic elimination'' of fast decaying degrees of freedom in open quantum systems can be performed with a series expansion in the timescale separation. The associ…
Gate generation for open quantum systems via a monotonic algorithm with time optimization
Paulo Sergio Pereira da Silva, Pierre Rouchon
We present a monotonic numerical algorithm including time optimization for generating quantum gates for open systems. Such systems are assumed to be governed by Lindblad master equ…
Online Parameter Estimation for Continuously Monitored Quantum Systems
Henrik Glavind Clausen, Pierre Rouchon, Rafal Wisniewski
In this work, we consider the problem of online (real-time, single-shot) estimation of static or slow-varying parameters along quantum trajectories in quantum dynamical systems. Ba…
Monitoring the energy of a cavity by observing the emission of a repeatedly excited qubit
Hector Hutin, Antoine Essig, Réouven Assouly +3
The number of excitations in a large quantum system (harmonic oscillator or qudit) can be measured in a quantum nondemolition manner using a dispersively coupled qubit. It typicall…
