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), workshops are in preparation
- Teaching sessions are organized for students and researchers (see below)
- A few starting research projects receive a support from IQUPS (see section "small project")
- An upgrade of a common fabrication facility is supported
- A theory post-doc in relation to experiments in an IQUPS lab has been selected
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 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!
IQUPS organizes 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!

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). To start with, 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.
The first series took place in March 2017, with one course on Optical Quantum Engineering (by Philippe Grangier) and one course on Electrical Quantum Engineering (by Patrice Bertet and Reinier Heeres) at building 503 of Orsay University. The ensemble of the two courses was 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). Notes relative to these courses are available at the following link: More information
A second series will take place on Wednesdays 27 September, 4, 18, and 25 October 2017, from 9am to 12:30, at building 503 of Orsay University. Course 1 on The NV Color Centre in Diamond: Physics and Applications (by Jean-François Roch), course 2 on Quantum optics of many-body systems (by Igor Mekhov). The ensemble of the two courses is 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).
Recent advances in Quantum Computing
13-14 december 2017, amphi Bloch at CEA Saclay
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.
Information on the program and an registration will be posted soon.
