The IQUPS project (in French: Ingénierie Quantique à l’Université Paris-Saclay) is an “Initiative de Recherche stratégique” of the Université Paris-Saclay.
The IQUPS project (in French: Ingénierie Quantique à l’Université Paris-Saclay) is an “Initiative de Recherche stratégique” of the Université Paris-Saclay. It aims at structuring research on quantum engineering at Université Paris-Saclay; at improving its visibility at the international level; and at strengthening this research by supporting: scientific reactivity on emerging subjects, theory in contact with experiments, and fabrication facilities.
- After the initial kick-off meeting (see below), a workshop on Quantum computing was orgnaized in december 2017, and a general meeting in March 2018.
- Teaching sessions are organized for students and researchers (see below)
- A few starting research projects receive a support from IQUPS. From 2018 on, IQUPS will co-support "small and medium equipment" projects submitted to SIRTEQ, see section "small projects".
- An upgrade of a common fabrication facility is supported
- A theory post-doc in relation to experiments in an IQUPS lab has been founded
IQUPS organizes a series of introductory lectures on Quantum Engineering. They are open to Master students, PhD students, Post-docs, and researchers. See the Teaching page!
The kick-off meeting of IQUPS took place on January 20th 2017. It gathered 70 participants. There were 4 long talks and 23 short presentations.
IQUPS organized an international workshop on Recent Advances in Quantum Computing on December 13-14, at Amphi Bloch, SPEC, CEA-Saclay. More information in the Workshop page!
A workshop "1 year of IQUPS" took place on March 2nd 2018, with 10 oral presentations and 12 posters. More information here!

Geographic repartition of the participating laboratories (area of disks proportional to the number of permanent researchers involved in IQUPS) :
In the second phase of IQUPS, laboratories which are not any more attached to Université Paris-Saclay (CPhT, LSI, LTCI) cannot receive any support from IQUPS. They are however welcome to participate to the activities of IQUPS.
Teams involved in IQUPS, with the name of the correspondant(s) and links to the websites :

CSNSM : Centre de Sciences Nucléaires et de Sciences de la Matière (IN2P3, CNRS, UPSud)
Because of the high level of international competitiveness, reactivity to explore new research and engineering directions is mandatory. We want to favor the emergence of new ideas by supporting small risky projects, in particular those emerging from collaborations within UPSay triggered by IQUPS. This support is designed to give the initial kick to help maturation and obtain further funding (Labex, ANR). In 2017, the board of IQUPS selected 4 projects (presented below) after a call to all the participating teams. The selection was based on the criteria of novelty, absence of other funding, competition, risk, and of course adequacy with the objectives of IQUPS.
In 2018-2019, IQUPS coordinates with the DIM SIRTEQ:
The first initiative is related to the SIRTEQ call "small and medium equipment", open till July 9, 2018. This call supports "equipments or ensemble of equipments for an amount smaller than 150 k€ HT. The Région Ile-de-France support cannot exceed 66% of the total amount, and will be bounded to 50 k€ HT for each projet".
IQUPS teams that want to repond to this SIRTEQ call can apply for a co-support from IQUPS for an amount inferior to 25k€ HT.
To apply, indicate in the SIRTEQ file that you apply for an IQUPS support. Your file will be transmitted to the IQUPS steering comittee, who will decide whether it is ready to support the project, in case it is accepted by SIRTEQ. The projects need of course to agree with the IQUPS objectives (see here); young teams will be priviledged.
Laboratories which do not belong any more to Université Paris-Saclay cannot apply to this action.
IQUPS organize series of courses, with each time 4 mornings with two different courses in a row. Till now, all courses were eligible as « complément de formation initiale » for students from the Ecole Doctorale Ondes et Matière (EDOM) and the Ecole Doctorale Physique en Ile-de-France (EDPIF).
1st series (March 2017): Optical Quantum Engineering (by Philippe Grangier); Electrical Quantum Engineering (by Patrice Bertet and Reinier Heeres).
2nd series (September-October 2017): The NV Color Centre in Diamond: Physics and Applications (by Jean-François Roch); Quantum optics of many-body systems (by Igor Mekhov).
3d series (May-June 2018): Introduction to quantum computing by Anthony Leverrier (Inria Paris) and Mazyar Mirrahimi (Inria Paris); Nanofabrication techniques by Dominique Mailly (C2N)
Introduction to quantum computing:
In 1994, Peter Shor took the computer science community by surprise by devising an efficient algorithm for factoring that could run on a quantum computer. This was a totally unexpected discovery since the difficulty of factoring large integers is at the basis of most cryptosystems deployed today on the internet.
In this course, we will provide an introduction to quantum computing and review the main quantum algorithms, in particular Shor’s algorithm for factoring and Grover’s algorithm for searching in a database.
Building a large scale quantum computer capable of implementing such algorithms for real world data has turned out to be an extremely challenging project, due to the issue of decoherence. In a second part of the course, we will discuss approaches to fight decoherence, namely quantum error correction and quantum fault-tolerance

Recent advances in Quantum Computing (13-14 December 2017)
Building a universal quantum computer is considered as one of the most challenging goals of modern physics by making real and at the same time questioning many fundamental aspects of quantum mechanics.
The biggest issue is that the quantum state of a qubit register can be controlled only up to a finite precision, due to either fluctuating experimental parameters or to the uncontrolled interaction with the environment. Remarkably, this does not forbid the implementation of a quantum computer because errors can be corrected to some extent by redundantly encoding the information into “logical” qubits that consist of several “physical” qubits. In the recent years the control accuracy of few qubit registers progresses in a variety of physical systems : trapped ions, superconducting circuits, spins, … Several experiments have reported single-qubit-gate error rates below 0.1%, and two-qubit error rates below 1%, coming close to the “error rate threshold” of certain Quantum Error Correction (QEC) schemes. Experiments involving 10 to 50 qubits are planned for the near future.
In this context, many questions are pressing. On the experimental side: Are the experimental error rates really sufficient to implement QEC? What architecture can realistically reach the fault-tolerance level? On the theory side : Are there better QEC schemes less demanding in terms of physical qubits and gates overhead conceivable ? Are QEC schemes resilient to other error models than the simplistic ones? What is the “killer app” for a small-scale quantum computers with typically 50 physical qubits?
The goal of this workshop is to gather experts both on the theory and the experimental sides, and to address some of these issues.
