International Initiatives

• Partner 1: University of Yale

• The long-term collaborations with the teams of Michel H. Devoret, Robert J. Schoelkopf, Liang Jiang and Steven M. Girvin, enforced through a two year sabbatical visit of Mazyar Mirrahimi at Yale university, have led to a set of contributions ranging from the theoretical analysis and performance optimization of ongoing experiments on weak quantum measurements  [74] and preparation of non-classical field states through single photon Kerr effect  [77] to the design of new experiments on single qubit cooling  [69] and stabilization of maximally entangled states of superconducting qubits [8] by reservoir engineering techniques. Through these collaborations, Zaki Leghtas and Mazyar Mirrahimi have introduced a new direction for hardware-efficient universal quantum computation  [84] , [93] . These theoretical proposals have already led to groundbreaking experiments [10] , [9] , [4] . We are intending to formalize these collaborations through the creation of an Inria associated team in the framework of Inria@EastCoast program.

• Partner 2: University of SaoPaulo and Federal University of Santa Catarina

• Pierre Rouchon is collaborating with P. S. Pereira da Silva (Escola Politécnica – PTC, University of SaoPaulo, Brazil) and H. B. Silveira Federal (University of Santa Catarina (UFSC), Florianópolis, Brazil) on the system theory problems behind the experiment on the feedback stabilization of the photon box. These collaborations have recently led to a publication in IEEE Conference on Decision and Control [33] .
