Closed call – position assigned
CNR logo full

Enrolled Fellow: Marcello Graziosi
Start date: 1 September 2014

Supervisor: Dr Roberto Leoni
Host Institution: Istituto di Fotonica e Nanotecnologie (IFN), Consiglio Nazionale delle Ricerche (CNR)/Università di Roma “La Sapienza”
Duration: 36 months

40,508.00 € per year plus mobility allowances (max 12792.00 €, min 8954.40 €, depending on the family condition). Salary is not subject to personal income tax but only to contributions to the Italian social security system.

Research project
Integrated photonic circuits have a strong potential to implement quantum information processing in optical systems. In PICQUE, all the basic components of a photonic quantum processor will be addressed: generation, manipulation and detection of photon states. Furthermore, to obtain detectors suitable for scalable circuits involving tens of qubits, the PICQUE consortium will target to breakthroughs in terms of detectors functionality, efficiency and yield, including also their integration with a range of components. In this context, the research program at IFN, Rome, will be finalized in the improvement of the efficiency and yield of superconducting nanowires single photon detectors (SNSPDs)* by using different approaches:
1. Integrating SNSPDs in waveguides;
2. Developing a standalone system of SNSPDs coupled with optical fibers with system detection efficiency at the state of the art.
3. Investigating new types of photosensitive films.
4. Developing arrays of SNSPDs.
5. Integrating SNSPDs and SNSPD arrays with quantum-optics circuits.

Local training activities
The ESR will be involved in the research group of IFN-CNR in the Rome unit, under the supervision of Dr. Roberto Leoni. It is foreseen that the ESR be enrolled as a PhD student in a Doctoral School in Physical Sciences.

Eligibility Criteria
The candidates must meet all the criteria listed below:
1. Be, at the time of recruitment by the host organization, in the first 4 years (full-time equivalent) of their research careers and have not yet been awarded a doctoral degree. This is measured from the date when they obtained the degree, which would formally entitle them to embark on a doctorate, either in the country in which the degree was obtained or in the country in which the research training is provided, irrespective of whether or not a doctorate is envisaged.
2. Researchers can be of any nationality. They are required to undertake trans-national mobility (i.e. move from one country to another) when taking up their appointment.
3. At the time of recruitment by the host organization, must not have resided or carried out their main activity (work, studies, etc.) in Italy for more than 12 months in the 3 years immediately prior to the reference date. Short stays such as holidays and/or compulsory national service are not taken into account.
4. At the starting time of the positions, the candidates must have completed the courses that would have allowed them to enroll in a doctorate program either in the country where they are studying or in the country offering the position.
5. Gross living allowance is subject to employment laws and employer costs deduction.

1. Perform high quality research in the bespoke research project under the guidance of the supervisory team.
2. Meet the members of the supervisory team on a regular basis.
3. Participate in the activities of the Network as specified in the Grant Agreement and/or required by the node coordinator, including secondments in other network nodes and taking part in the network meetings and in the training activities.
4. Write up the results of the research activity and present research papers and publications at meetings and conferences, as advised by the supervisors.
5. Widen the personal knowledge in the research area and undertake complementary training.
6. Keep records of the activities, such as secondments, visits, leave of absence.

Person Specification
The successful candidates must satisfy the eligibility criteria (see below) and have:
1. MSc degree (or equivalent) in physics or engineering or disciplines close to the project research areas is required. A preferential title will be a documented experience in applied optics.
2. A keen interest in pursuing research in photonic device physics, nanotechnologies and in particular the science and technology of superconducting nanowires.
3. The ability to work independently, and as a member of a research team.
4. Excellent interpersonal and communication skills.
5. A good command of English language.
