Ultrahigh- on-chip silicon-germanium microresonators
Ryan Schilling, Chi Xiong, Swetha Kamlapurkar +7
We demonstrate fully crystalline, single-mode ultrahigh quality factor integrated microresonators comprising epitaxially grown SiGe waveguide cores with silicon c…
Investigating microwave loss of SiGe using superconducting transmon qubits
Martin Sandberg, Vivekananda P. Adiga, Markus Brink +6
Silicon-Germanium (SiGe) is a material that possesses a multitude of applications ranging from transistors to eletro-optical modulators and quantum dots. The diverse properties of…
High-fidelity superconducting quantum processors via laser-annealing of transmon qubits
Eric J. Zhang, Srikanth Srinivasan, Neereja Sundaresan +19
Scaling the number of qubits while maintaining high-fidelity quantum gates remains a key challenge for quantum computing. Presently, superconducting quantum processors with >50-qub…
Laser-annealing Josephson junctions for yielding scaled-up superconducting quantum processors
Jared B. Hertzberg, Eric J. Zhang, Sami Rosenblatt +8
As superconducting quantum circuits scale to larger sizes, the problem of frequency crowding proves a formidable task. Here we present a solution for this problem in fixed-frequenc…
Development of Quantum InterConnects for Next-Generation Information Technologies
David Awschalom, Karl K. Berggren, Hannes Bernien +32
Just as classical information technology rests on a foundation built of interconnected information-processing systems, quantum information technology (QIT) must do the same. A crit…
A monolithic 56 Gb/s silicon photonic pulse-amplitude modulation transmitter
Chi Xiong, Douglas M. Gill, Jonathan E. Proesel +3
Silicon photonics promises to address the challenges for next-generation short-reach optical interconnects. Growing bandwidth demand in hyper-scale data centers and high-performanc…
Photonic Crystal Microcavities in a Microelectronics 45nm SOI CMOS Technology
Christopher V. Poulton, Xiaoge Zeng, Mark T. Wade +3
We demonstrate the first monolithically integrated linear photonic crystal microcavities in an advanced SOI CMOS microelectronics process (IBM 45nm 12SOI) with no in-foundry proces…
