First microsecond velocity-space resolved simultaneous measurements of co- and counter-current fast-ion losses in forward and reverse magnetic field in a tokamak Open
A novel Fast Ion Loss Detector was designed, manufactured, installed and commissioned at the Tokamak á Configuration Variable. This is the first Fast Ion Loss Detector to feature four collimators that enable simultaneous detection of co- a…

A Complete Equational Theory for Quantum Circuits Open
We introduce the first complete equational theory for quantum circuits. More\nprecisely, we introduce a set of circuit equations that we prove to be sound\nand complete: two circuits represent the same unitary map if and only if they\ncan …

Gas puff imaging on the TCV tokamak Open
We present the design and operation of a suite of Gas Puff Imaging (GPI) diagnostic systems installed on the Tokamak à Configuration Variable (TCV) for the study of turbulence in the plasma edge and Scrape-Off-Layer (SOL). These systems pr…

Characterization and modelling of the hygro-viscoelastic behaviour of polymer-based composites used in marine environment Open
This paper presents results from a study of the long-term behaviour of carbon/epoxy composites. The interactions between ageing in water and constant mechanical loads are described, first experimentally then using a simple modelling approa…

Resource Optimisation of Coherently Controlled Quantum Computations with the PBS-calculus Open
Coherent control of quantum computations can be used to improve some quantum protocols and algorithms. For instance, the complexity of implementing the permutation of some given unitary transformations can be strictly decreased by allowing…

LO_v-Calculus: A Graphical Language for Linear Optical Quantum Circuits Open
We introduce the LO_v-calculus, a graphical language for reasoning about linear optical quantum circuits with so-called vacuum state auxiliary inputs. We present the axiomatics of the language and prove its soundness and completeness: two …
