(DURIP) HIGH-SPEED WAVEFORM ELECTRONICS FOR QUANTUM INFORMATION SCIENCE WITH SUPERCONDUCTING CIRCUITS
Abstract
Funds are requested in this proposal to acquire a system of high-speed waveform genera- tors and digitizers in the Plourde lab at Syracuse University for complex manipulation and measurement of superconducting quantum circuits. The PI has multiple intensive research e orts in the area of Quantum Information Science (QIS), including a range of projects with funding through the DoD, that would bene t greatly from this instrument acquisition. PI Plourde is currently exploring: the development of novel qubit designs that are exponentially protected against decoherence by topology and could lead to signi cant enhancements in gate delity; con gurations of superconducting metamaterials that could provide a route for im- plementing analog quantum simulations with microwave photons, as well as the possibility of implementing ecient quantum transducers between microwave and optical photons; hy- brid multiqubit architectures that combine di erent superconducting qubit types that can eliminate unwanted two-qubit interactions and provide a path towards improved two-qubit gate delities; the integration of superconducting classical digital circuitry based on single ux quantum (SFQ) logic for controlling and reading out superconducting qubits, which can thus o er a route to overcome the signi cant overhead challenges to scaling to large qubit arrays associated with conventional state-of-the-art microwave-based control and readout. All of these e orts have substantial instrumentation requirements for high-speed waveform electronics for generating and sequencing complex electrical signals for manipulating quan- tum states of superconducting circuits and performing measurements. The current waveform generation and digitization capabilities in the PI s lab consist of a combination of custom and commercial hardware that has worked well for many years, but is currently becoming obsolete with multiple limitations, including memory depth, speed, and programmability, compared to modern high-speed electronics systems designed for interfacing with super- conducting qubit arrays. The addition of this new system will signi cantly enhance the high-speed waveform capabilities in the Plourde lab and will allow more rapid progress on the various project goals and enable new experimental e orts. The acquisition of this in- strumentation will also enhance ongoing research-related education associated with these projects. The students and postdoctoral researchers involved are part of cutting-edge e orts in QIS and superconducting device technology, both critical areas of interest to the DoD.
