New Papers!

Hatlab is proud to share its two new papers on quantum-limited amplifiers, which have just been published in Phys, Rev. A: the first is a theoretical description of optimization via full Hamiltonian control, the other is an experimental focus on a Kerr-free amplifier design with qubit measurement. Please check them out here:
Experiment: Multiparametric amplification and qubit measurement with a Kerr-free Josephson ring modulator;
Theory: Optimizing Josephson-ring-modulator-based Josephson parametric amplifiers via full Hamiltonian control

Fullerton and Hatridge named 2020 Sloan Research Fellows

Congratulations to both Prof. Susan Fullerton in Pitt Chemical Engineering and Prof. Michael Hatridge in Pitt Physics as recipients of 2020 Sloan Research Fellowships! Awarded annually since 1955, the fellowships honor scholars in the U.S. and Canada whose creativity, leadership, and independent research achievements make them some of the most promising researchers working today. Winners receive $75,000, which may be spent over a two-year term on any expense supportive of their research.


PQI Graduate Student Research Award

Graduate student Tzu-Chiao Chien won the PQI graduate student research award for his thriving experiments on 'Broadband bi-directional amplification via paired simultaneous parametric drives'. Congratulations TZC!

Arts & Sciences Graduate Fellow in the Physics & Astronomy Department

Graduate student Xi Cao was awarded the Art & Science Graduate Fellowship for his pioneering experiments on 'Experimental realization of chemical potential for light via parametric coupling'. Congratulations Xi!

Emil Sanielevici Undergraduate Research Scholarship

Undergraduate senior Sarah Motz was awarded the Emil Sanielevici Research Scholarship, given annually to an undergraduate major in the Physics department to encourage enthusiasm for scientific research. Sarah won for her proposal to improve qubit coherence times through the use of a cavity attenuator. Congratulations Sarah!



HatLab is pleased to announce that it will be leading an international team to discover the best materials for quantum information processing platforms. Along with Dr. Michael Hatridge, the other co-principle investigators will be Dr. Frolov, Dr. Petek and Dr. Peker from Pitt. Pitt will lead the five-year collaboration with Carnegie Mellon University; the University of California, Santa Barbara; French partners from the Centre National de la Recherche Scientifique and Commissariat Ó l'Únergie atomique et aux Únergies alternatives; and industrial partner Microsoft Research. The PIRE program will bring together materials engineers, surface scientists, computational chemists and physicists, as well as students from all levels at Pitt. Researchers will also have the opportunity to conduct research in France. Check it out here: https://www.pittwire.pitt.edu/news/pitt-lead-international-team-create-hardware-quantum-computers

Xi Cao Wins QuInternship

5th Year graduate student, Xi Cao, has won a competitive internship called the Quantum Big Leap Idea, a cross-NSF activity focused on the development of quantum technologies. He will be fulfilling this internship partially at IBM in Yorktown Heights, NY for the next 3 years. Congrats Xi!


New Initiatives Grant from the Charles E. Kaufman Foundation

The Hatlab has just been awarded the New Initiatives Grant from the Charles E. Kaufman foundation at the Pittsburgh foundation. This grant is offered to scientists in Pennsylvania who explore questions which go beyond the abilities of a single researcher fostering interdisciplinary collaboration. This grant will aid in the lab's joint effort with Professor Roger Mong to create new topologically protected quantum wiring for quantum ciruits. The effort will be a fusion of the rapidly developing fields of superconducting quantum circuits, manipulation of quantum light and the physics of topological materials.

Pennsylvania Space Grant Consortium Research Scholarship

We are happy to report that Hatlab's newest member, Sarah Motz, has received the Pennsylvania Space Grant Consortium Research Scholarship for summer 2017! This scholarship is paid by NASA to encourage undergraduate students to participate in STEM research. With her scholarship, Sarah will be working on a new quantum amplifier design in order to minimize frequency loss and increase magnetic coupling strength. Congratulations Sarah!

Emil Sanielevici Undergraduate Research Scholarship

Undergraduate sophomore Edan Alpern was awarded the Emil Sanielevici Scholarship, given annually to an undergraduate major in the Physics department to encourage enthusiasm for scientific research. Edan won for his proposal to improve the behavior of our quantum limited amplifiers by creating a circuit without Kerr terms. Congratulations Edan!
