Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental limitations imposed by quantum mechanics. The Heisenberg uncertainty p

Single and coupled cavity mode sensing schemes using a diagnostic field

Autor: Goodwin-Jones, Aaron W., Zhu, Haochen, Blair, Carl, Brown, Daniel D., van Heijningen, Joris, Ju, Li, Zhao, Chunnong

Precise optical mode matching is of critical importance in experiments using squeezed-vacuum states. Automatic spatial-mode matching schemes have the potential to reduce losses and improve loss stability. However, in quantum-enhanced coupled-cavity e

Universal logic with encoded spin qubits in silicon

Autor: Weinstein, Aaron J., Reed, Matthew D., Jones, Aaron M., Andrews, Reed W., Barnes, David, Blumoff, Jacob Z., Euliss, Larken E., Eng, Kevin, Fong, Bryan, Ha, Sieu D., Hulbert, Daniel R., Jackson, Clayton, Jura, Michael, Keating, Tyler E., Kerckhoff, Joseph, Kiselev, Andrey A., Matten, Justine, Sabbir, Golam, Smith, Aaron, Wright, Jeffrey, Rakher, Matthew T., Ladd, Thaddeus D., Borselli, Matthew G.

Qubits encoded in a decoherence-free subsystem and realized in exchange-coupled silicon quantum dots are promising candidates for fault-tolerant quantum computing. Benefits of this approach include excellent coherence, low control crosstalk, and conf

The optical design of the Einstein Telescope (ET) is based on a dual-recycled Michelson interferometer with Fabry-Perot cavities in the arms. ET will be constructed in a new infrastructure, allowing us to consider different technical implementations
