Preprint / Working Paper
Semizoglou, E., Lo Re, L., Middleton, S. J., Perez-Sanchez, J., Tufarelli, T., Bennett, D. L., & Chisholm, K. I. Characterising the stimulus-response function of mouse C-Low threshold mechanoreceptors to mechanical stimuliin vivo

C-low threshold mechanoreceptors (C-LTMRs) in animals (termed C-tactile (CT) fibres in humans) are a subgroup of C-fibre primary afferents, which innervate hairy skin and respond to low threshold punctate indentations and brush stimuli. These afferen... Read More about Characterising the stimulus-response function of mouse C-Low threshold mechanoreceptors to mechanical stimuliin vivo.

Quantum estimation of coupling strengths in driven-dissipative optomechanics (2021)
Journal Article

We exploit local quantum estimation theory to investigate the measurement of linear (g1) and quadratic (g2) coupling strengths in a driven-dissipative optomechanical system in the red-sideband regime. We consider model parameters inspired by recent e... Read More about Quantum estimation of coupling strengths in driven-dissipative optomechanics.

Single quantum emitter Dicke enhancement (2021)
Journal Article
Tufarelli, T., Friedrich, D., Groß, H., Hamm, J., Hess, O., & Hecht, B. (2021). Single quantum emitter Dicke enhancement. Physical Review Research, 3(3), Article 033103. https://doi.org/10.1103/physrevresearch.3.033103

Coupling N identical emitters to the same field mode is well-established method to enhance light matter interaction. However, the resulting √ N-boost of the coupling strength comes at the cost of a "linearized" (effectively semi-classical) dynamics.... Read More about Single quantum emitter Dicke enhancement.

General Expressions for the Quantum Fisher Information Matrix with Applications to Discrete Quantum Imaging (2021)
Journal Article

The quantum Fisher information matrix is a central object in multiparameter quantum estimation theory. It is usually challenging to obtain analytical expressions for it because most calculation methods rely on the diagonalization of the density matri...

Non-Orthogonal Bases for Quantum Metrology (2019)
Journal Article

Many quantum statistical models are most conveniently formulated in terms of non-orthonormal bases. This is the case, for example, when mixtures and superpositions of coherent states are involved. In these instances, we show that the analytical evalu... Read More about Non-Orthogonal Bases for Quantum Metrology.

Towards superresolution surface metrology: quantum estimation of angular and axial separations (2019)
Journal Article

We investigate the localization of two incoherent point sources with arbitrary angular and axial separations in the paraxial approximation. By using quantum metrology techniques, we show that a simultaneous estimation of the two separations is achiev...

Exploring corrections to the optomechanical Hamiltonian (2018)
Journal Article

We compare two approaches for deriving corrections to the “linear model” of cavity optomechanics, in order to describe effects that are beyond first order in the radiation pressure coupling. In the regime where the mechanical frequency is much lower... Read More about Exploring corrections to the optomechanical Hamiltonian.

Strong coupling and resultant mixing of light and matter states is an important asset for future quantum technologies. Here we demonstrate deterministic room-temperature strong coupling of a mesoscopic colloidal quantum dot to a plasmonic nano resona...

Einstein-Podolsky-Rosen (EPR) steering is an asymmetric form of correlations which is intermediate between quantum entanglement and Bell nonlocality, and can be exploited as a resource for quantum communication with one untrusted party. In particular... Read More about Investigating Einstein-Podolsky-Rosen steering of continuous-variable bipartite states by non-Gaussian pseudospin measurements.

We propose an information-theoretic framework to quantify multipartite correlations in classical and quantum systems, answering questions such as: what is the amount of seven-partite correlations in a given state of ten particles? We identify measure... Read More about Quantifying genuine multipartite correlations and their pattern complexity.
