In September 2015 I have been accepted as "Investigador Asistente" (Tenured Researcher / Charché de Recherche) at CONICET. I am currently awaiting for the formal designation, which should happen in 2016. I continue also with the faculty position I have since August 2014 as "Profesor Adjunto con Dedicación Exclusiva" (Tenured Assistant Professor / Maître de Conférences) at Universidad Nacional de Quilmes, in the Departamento de Ciencia y Tecnología. I am part of the LoReL team, and also integrate the Logics and Dynamics of Programming Languages team of the Laboratoire International Associé INFINIS.
From January to July 2016 I was a visiting researcher at Universià degli Studi di Torino in the Dipartamento di Informatica, funded by the World Wide Style Project.
From October 2012 to August 2014 I had a nontenured teaching and research position (ATER) at Université Paris Ouest Nanterre La Défense, in the Département de Mathématique et d'Informatique and
I was an associated member of the Deducteam team at INRIA ParisRocquencourt.
Before that, I did a postdoc from October 2011 to September 2012 at Université Paris 13, the LIPN laboratory, within the LCR team.
Even before that, between October 2008 and September 2011, I prepared my PhD thesis within the CAPP team at the LIG Laboratory of the Université de Grenoble, with Pablo Arrighi as advisor and Frédéric Prost as coadvisor. The thesis defense happened on September 23, 2011. You can download my thesis “Du typage vectoriel”, as well as the slides used during the presentation, and even a video, in the publications section bellow.
In the prehistory I graduated in Computer Science from the Universidad Nacional de Rosario, Argentina in December 2007.

Typing quantum superpositions and projective measurements

A. DíazCaro and G. Dowek
 arXiv:1601.04294  2016
[ arXiv  slides (CLAM'16) ]
We study a purely functional quantum extension of lambda calculus, that is, an extension of lambda calculus to express some quantum features, where the quantum memory is abstracted out. This calculus is a typed extension of the firstorder linearalgebraic lambdacalculus. The type is linear on superpositions, so to forbid from cloning them, while allows to clone basis vectors. We provide examples of the Deutsch algorithm and the Teleportation, and prove the subject reduction of the calculus. In addition, we provide a denotational semantics where superposed types are interpreted as vector spaces and nonsuperposed types as their basis.

The vectorial λcalculus

 Considered for publication in I&C  arXiv:1308.1138  2015
[ arXiv ]
We describe a type system for the linearalgebraic
λcalculus. The type system accounts for the linearalgebraic aspects of this extension of λcalculus: It is
able to statically describe the linear combinations of terms
that will be obtained when reducing the programs. This gives rise to an
original type theory where types, in the same way as terms, can be
superposed into linear combinations.
We prove that the resulting
typed λcalculus is strongly normalising and features a weak subject reduction. Finally,
we show how to naturally encode matrices and vectors in this typed calculus.

Simply typed lambdacalculus modulo type isomorphisms

We define a simply typed, nondeterministic lambdacalculus where isomorphic types are equated. To this end, an equivalence relation is settled at the term level. We then provide a proof of strong normalisation modulo equivalence. Such a proof is a nontrivial adaptation of the reducibility method.

[ arXiv  LNCS  slides ]
We introduce a quantumlike classical computational model, called affine computation, as a generalization of probabilistic computation. After giving the basics of affine computation, we define affine finite automata (AfA) and compare it with quantum and probabilistic finite automata (QFA and PFA, respectively) with respect to three basic language recognition modes. We show that, in the cases of bounded and unbounded error, AfAs are more powerful than QFAs and PFAs, and, in the case of nondeterministic computation, AfAs are more powerful than PFAs but equivalent to QFAs.

Isomorphisms considered as equalities
Projecting functions and enhancing partial application through an implementation of λ⁺

 (IFL 2015)  To appear in ACM postproceedings, 2016.
[ arXiv  prototipe ]
We propose an implementation of λ⁺, a recently introduced simply typed lambdacalculus with pairs where isomorphic types are made equal. The rewrite system of λ⁺ is a rewrite system modulo an equivalence relation, which makes its implementation nontrivial. We also extend λ⁺ with natural numbers and general recursion and use Bekić's theorem to split mutual recursions. This splitting, together with the features of λ⁺, allows for a novel way of program transformation by reduction, by projecting a function before it is applied in order to simplify it. Also, currying together with the associativity and commutativity of pairs gives an enhanced form of partial application.

Callbyvalue, callbyname and the vectorial behaviour of the algebraic λcalculus

We examine the relationship between the algebraic λcalculus, a fragment of the differential λcalculus and the linearalgebraic λcalculus, a candidate λcalculus for quantum computation. Both calculi are algebraic: each one is equipped with an additive and a scalarmultiplicative structure, and their set of terms is closed under linear combinations. However, the two languages were built using different approaches: the former is a callbyname language whereas the latter is callbyvalue; the former considers algebraic equalities whereas the latter approaches them through rewrite rules.
In this paper, we analyse how these different approaches relate to one another. To this end, we propose four canonical languages based on each of the possible choices: callbyname versus callbyvalue, algebraic equality versus algebraic rewriting. We show that the various languages simulate one another. Due to subtle interaction between betareduction and algebraic rewriting, to make the languages consistent some additional hypotheses such as confluence or normalisation might be required. We carefully devise the required properties for each proof, making them general enough to be valid for any sublanguage satisfying the corresponding properties.

We show how to provide a structure of probability space to the set of execution traces on a nonconfluent abstract rewrite system, by defining a variant of a Lebesgue measure on the space of traces. Then, we show how to use this probability space to transform a nondeterministic calculus into a probabilistic one. We use as example λ_{+}, a recently introduced calculus defined with techniques from deduction modulo.

Callbyvalue nondeterminism in a linear logic type discipline

We consider the callbyvalue λcalculus extended with a mayconvergent nondeterministic choice and a mustconvergent parallel composition. Inspired by recent works on the relational semantics of linear logic and nonidempotent intersection types, we endow this calculus with a type system based on the socalled Girard's second translation of intuitionistic logic into linear logic. We prove that a term is typable if and only if is converging, and that its typing tree carries enough information to give a bound on the length of its lazy callbyvalue reduction. Moreover, when the typing tree is minimal, such a bound becomes the exact length of the reduction.

We consider the nondeterministic extension of the callbyvalue lambda calculus, which corresponds to the additive fragment of the linearalgebraic lambdacalculus. We define a finegrained type system, capturing the right linearity present in such formalisms. After proving the subject reduction and the strong normalisation properties, we propose a translation of this calculus into the System F with pairs, which corresponds to a non linear fragment of linear logic. The translation provides a deeper understanding of the linearity in our setting.

The Algebraic lambdacalculus and the LinearAlgebraic lambdacalculus extend the lambdacalculus with the possibility of making arbitrary linear combinations of terms. In this paper we provide a finegrained, System Flike type system for the linearalgebraic lambdacalculus. We show that this Scalar type system enjoys both the subjectreduction property and the strongnormalisation property, our main technical results. The latter yields a significant simplification of the linearalgebraic lambdacalculus itself, by removing the need for some restrictions in its reduction rules. But the more important, original feature of this scalar type system is that it keeps track of 'the amount of a type' that is present in each term. As an example of its use, we shown that it can serve as a guarantee that the normal form of a term is barycentric, i.e. that its scalars are summing to one.

The linearalgebraic λcalculus and the algebraic λcalculus are untyped λcalculi extended with arbitrary linear combinations of terms. The former presents the axioms of linear algebra in the form of a rewrite system, while the latter uses equalities. When given by rewrites, algebraic λcalculi are not conﬂuent unless further restrictions are added. We provide a type system for the linearalgebraic λcalculus enforcing strong normalisation, which gives back conﬂuence. The type system allows an interpretation in System F.

We examine the relationship between the algebraic lambdacalculus λ_{alg}, a fragment of the differential lambdacalculus, and the linearalgebraic lambdacalculus λ_{lin}, a candidate lambdacalculus for quantum computation. Both calculi are algebraic: each one is equipped with an additive and a scalarmultiplicative structure, and the set of terms is closed under linear combinations. We answer the conjectured question of the simulation of λ_{alg} by λ_{lin} and the reverse simulation of λ_{lin} by λ_{alg}. Our proof relies on the observation that λ_{lin} is essentially callbyvalue, while λ_{alg} is callbyname. The former simulation uses the standard notion of thunks, while the latter is based on an algebraic extension of the continuation passing style. This result is a step towards an extension of callbyvalue / callbyname duality to algebraic lambdacalculi

The LinearAlgebraic LambdaCalculus (arXiv:quantph/0612199) extends the lambdacalculus with the possibility of making arbitrary linear combinations of terms a.t+b.u. Since one can express fixed points over sums in this calculus, one has a notion of infinities arising, and hence indefinite forms. As a consequence, in order to guarantee the confluence, tt does not always reduce to 0  only if t is closed normal. In this paper we provide a System F like type system for the LinearAlgebraic LambdaCalculus, which guarantees normalisation and hence no need for such restrictions, tt always reduces to 0. Moreover this type system keeps track of 'the amount of a type'. As such it can be seen as probabilistic type system, guaranteeing that terms define correct probabilistic functions. It can also be seen as a step along the quest toward a quantum physical logic through the CurryHoward isomorphism.

This paper demonstrates how to add a measurement operator to quantum lambdacalculi. A proof of the consistency of the semantics is given through a proof of confluence presented in a sufficiently general way to allow this technique to be used for other languages. The method described here may be applied to probabilistic rewrite systems in general, and to add measurement to more complex languages such as QML or Lineal, which is the subject of further research.

The objective of this thesis is to develop a type theory for the linearalgebraic λcalculus, an extension of λcalculus motivated by quantum computing. This algebraic extension encompass all the terms of λcalculus together with their linear combinations, so if t and r are two terms, so is α.t + β.r, with α and β being scalars from a given ring. The key idea and challenge of this thesis was to introduce a type system where the types, in the same way as the terms, form a vectorial space, providing the information about the structure of the normal form of the terms. This thesis presents the system Lineal, and also three intermediate systems, however interesting by themselves: Scalar, Additive and λCA, all of them with their subject reduction and strong normalisation proofs.
