Extending qubit lifetime through a shaped environment Qubits are the quantum two-level systems that encode and process information in quantum computing. Kept in isolation, qubits can be stable. In a practical setting, however, qubits must be addresse

In the cavity-QED architecture, photon number fluctuations from residual cavity photons cause qubit dephasing due to the ac Stark effect. These unwanted photons originate from a variety of sources, such as thermal radiation, leftover measurement phot

Cryogenic test fixture for two-port calibration at 4.2 K and above

Autor: Daniel E. Oates, Richard L. Slattery, David Hover

Publikováno v: 2017 89th ARFTG Microwave Measurement Conference (ARFTG).

A test fixture for full 2-port-calibrated, error-corrected measurements at cryogenic temperatures has been built and tested. Through-reflect-line (TRL) calibrations have been demonstrated at frequencies up to 4.5 GHz and at temperatures as low as 4.2
