Michel H. Devoret
phone : 203-432-4273
Michel Devoret graduated from Ecole Nationale Superieure des Telecommunications in Paris in 1975 and started graduate work in molecular quantum physics at the University of Orsay. He then joined Professor Anatole Abragam’s laboratory in CEA-Saclay to work on NMR in solid hydrogen, and received his PhD from Paris University in 1982. He spent two post-doctoral years working on macroscopic quantum tunneling with John Clarke’s laboratory at the University of California, Berkeley. He pursued this research on quantum mechanical electronics upon his return to Saclay, starting his own research group with Daniel Esteve and Cristian Urbina. The main achievements of the “quantronics group” were in this period the measurement of the traversal time of tunneling, the invention of the single electron pump (now the basis of a new standard of capacitance), the first measurement of the effect of atomic valence on the conductance of a single atom, and the first observation of the Ramsey fringes of a superconducting artificial atom (quantronium). He became director of research at the Commissariat a l’Energie Atomique (CEA) at Saclay. In 2007, Michel has been appointed to the College de France, where he taught until 2012. He is a member of the American Academy of Arts and Sciences (2003) and a member of the French Academy of Sciences (2008). Michel has received the Ampere Prize of the French Academy of Science (together with Daniel Esteve, 1991), the Descartes-Huygens Prize of the Royal Academy of Science of the Netherlands (1996) and the Europhysics-Agilent Prize of the European Physical Society (together with Daniel Esteve, Hans Mooij and Yasunobu Nakamura, 2004). He is also a recipient of the John Stewart Bell Prize, which he received jointly with Rob Schoelkopf in 2013. In 2014, he has been awarded, together with John Martinis and Rob Schoelkopf, the Fritz London Memorial Prize. He received the Olli Lounaasma Prize in 2016.
Currently the F. W. Beinecke Professor of Applied Physics at Yale University — which he joined in 2002 — he focuses his research on experimental solid state physics with emphasis on quantum mechanical electronics (a.k.a. “quantronics”) for quantum information processing. In this new type of electronics, electrical collective degrees of freedom like currents and voltages behave quantum mechanically. Such mesoscopic phenomena are particularly important in quantum circuits based on Josephson junctions, which is his main research goal. He currently focuses on the new phenomena of fault-tolerant quantum operations and remote entanglement.
Luigi Frunzio
phone : 203-432-4268
Luigi received his Masters in Physics at Federico II University in Naples, Italy, earning 110/110 Cum Laude. His thesis studied the effects of the intrinsic fluctuations in current biased Josephson tunnel junctions, and his preliminary work took place at the Superconductivity Department of the Instituto di Cibernetica of the CNR under the supervision of Professors Arturo Tagliacozzo and Roberto Cristiano. He also has a PhD from Orsay University. Luigi is currently a Senior Research Scientist at the Department of Applied Physics at Yale University. He works jointly with Prof. Devoret and Prof. Schoelkopf on experiments involving superconducting qubits. His curriculum vitae is available here

Rodrigo Cortiñas
Rodrigo was born and raised in Lomas de Zamora, a suburb of the Argentine capital. He studied Physics at the University of Buenos Aires, where his final undergrad project was on single optical photon quantum optics in the LOFT lab (Claudio Iemmi). He then moved to Paris, France to work in the cavity QED team of the LKB lab (Serge Haroche, Jean-Michel Raimond, and Michel Brune) on the development of Rydberg atoms technology for quantum simulation. They were the first team to laser trap circular Rydberg atoms (and for >10ms!), an achievement for which Rodrigo was awarded a PhD in atomic physics from the ENS (PSL). He then moved to Yale and joined Qlab to work on quantum error correction in circuit QED. Rodrigo is interested in the fundamental aspects of quantum mechanics and how to harvest them.
