A new carbon nanotube-based filter for quantum computing applications
Wednesday, December 4, 2019 En français Superconducting quantum circuits are sensitive to electromagnetic interference and thermal radiation, and such interactions with the environment lead to the undesirable phenomenon of quantum decoherence. Commercially available filters, such as lumped-element filters and waveguide-based filters, become leaky or simply stop working above certain frequencies. While lossy transmission line […]

Developing Tools for Quantum Characterization and Validation
Summary Coherence is essential for quantum computation; yet it introduces a unique sensitivity to any imperfections in hardware design, control systems, and the operating environment. Overcoming these sensitivities requires a hierarchy of strategies, ranging from optimization of the hardware architecture to software solutions including quantum error correction. Randomized Benchmarking Protocols are an important family of […]
