Two WQI graduate students, Chuanhong (Vincent) Liu (McDermott Group) and Cecilia Vollbrecht (Goldsmith Group), have had their projects awarded funding through QISE-NET, the Quantum Information Science and Engineering Network. Run through the University of Chicago, QISE-NET is open to any student pursuing an advanced degree in any field of quantum science. Liu, Vollbrecht, and other students in their cohort earn up to three years of support, including funding, mentoring and training at annual workshops. All awardees are paired with a mentoring QISE company or national lab, at which they will complete part of their projects. Liu and Vollbrecht explain their projects below.

“The Single Flux Quantum (SFQ) digital logic family has been proposed as a scalable approach for the control of next-generation multiqubit arrays. With NIST’s strong track record in the field of SFQ digital logic and the expertise of McDermott’s lab in the superconducting qubit area, we expect to achieve high fidelity SFQ-based qubit control. The successful completion of this research program will represent a major step forward in the development of a scalable quantum-classical interface, a critical component of a fully error-corrected fault-tolerant quantum computer.”

“The goal of my proposal is to develop a coupled cavity array that will allow us to simulate complex quantum phenomena. With the partnership between NIST and Prof. Goldsmith’s group I can combine the expertise of both groups to create an array where we characterize energy transfer and loss pathways, couplings, and coherence. The knowledge gained from these experiments will help to make a highly controlled cavity quantum electrodynamics platform.”

“The research I proposed aims to, with the help of Argonne National Lab’s computational expertise, build a platform that models and simulates the performance of the atomic qubit array (AQuA) experiment in Prof. Saffman’s lab. This could help us to understand the effect of various technical problems, such as laser noise, in the experiment, and guide us in improving the gate fidelities. On the other hand, the platform could also be a useful tool in simulating and designing novel quantum gate protocols and quantum algorithms that can be performed on AQuA.”

“We are developing a new type of superconducting qubit that provides protection from noise and decoherence at the hardware level. Our near-term goals are to prepare quantum superposition states and to transfer them into the protected regime where we will look for extended energy relaxation and dephasing times. We will next implement protected gates, which we will characterize by doing interleaved randomized benchmarking.”

First cohort of students dives into new quantum computing master’s degree

The inaugural MS in Physics–Quantum Computing is the first program of its kind in the U.S. It addresses an emerging workforce need by preparing students to enter this rapidly growing and highly complex field. Most of the students will complete their degrees August. We checked in with them after their first semester to see how their studies were going.
