Robert Niffenegger

Robert Niffenegger is an Adjunct Assistant Professor in the Department of Physics at the University of Massachusetts. He leads the UMass Trapped Ion Quantum Computing and Photonics Lab, focusing on developing integrated technologies for trapped ion quantum processors (QPUs) and photonics. His research addresses challenges in scalable quantum computing, such as reducing heating rates in ion traps and integrating photonics for precise qubit control.

He previously worked at MIT Lincoln Laboratory, where his team demonstrated integrated photonics for trapped ion QPUs, including a Nature-published study on photonic grating couplers and ion control. Current projects include cryogenic vacuum chambers to enhance qubit performance, monolithic electronics integration, and remote entanglement generation via photonic Mach-Zehnder interferometers.

Research interests span quantum hardware development, integrated photonics, cryogenics, and scalable quantum systems. His lab collaborates with MITLL on photonic chip fabrication and explores applications in optical clocks and quantum networking. The lab has open positions for postdocs, PhD students, and undergraduates, emphasizing experimental physics, photonics, and cryogenic systems.

Notable achievements include the NSF CAREER Award for advancing trapped ion QPU technology and pioneering integrated photonic platforms for quantum computing. The lab’s sponsors include NSF and MIT Lincoln Laboratory.
