The persistence of spin coherence in a crystalline environment

Autor: Curran III, Gerald, Rex, Zachary, Wilson, Casper X., Weaver, Luke J., Biaggio, Ivan

Publikováno v: Phys. Rev. Lett. vol. 133(5), 056901 (2024)

We analyze quantum interference in the triplet-exciton pair generated by singlet exciton fission in a molecular crystal, and introduce transport-induced dephasing (TID) as a key effect that can suppress the expected fluorescence quantum beats when th

Qubit teleportation between a memory-compatible photonic time-bin qubit and a solid-state quantum network node

Autor: Iuliano, Mariagrazia, Slater, Marie-Christine, Stolk, Arian J., Weaver, Matthew J., Chakraborty, Tanmoy, Loukiantchenko, Elsie, Amaral, Gustavo Castro do, Alfasi, Nir, Sholkina, Mariya O., Tittel, Wolfgang, Hanson, Ronald

We report on a quantum interface linking a diamond NV center quantum network node and 795nm photonic time-bin qubits compatible with Thulium and Rubidium quantum memories. The interface makes use of two-stage low-noise quantum frequency conversion an

Coherent Coupling of a Diamond Tin-Vacancy Center to a Tunable Open Microcavity

Autor: Herrmann, Yanik, Fischer, Julius, Brevoord, Julia M., Sauerzapf, Colin, Wienhoven, Leonardo G. C., Feije, Laurens J., Pasini, Matteo, Eschen, Martin, Ruf, Maximilian, Weaver, Matthew J., Hanson, Ronald

Publikováno v: Phys. Rev. X 14, 041013 (2024)

Efficient coupling of optically active qubits to optical cavities is a key challenge for solid-state-based quantum optics experiments and future quantum technologies. Here we present a quantum photonic interface based on a single Tin-Vacancy center i

Optical readout of a superconducting qubit using a scalable piezo-optomechanical transducer

Autor: van Thiel, T. C., Weaver, M. J., Berto, F., Duivestein, P., Lemang, M., Schuurman, K. L., Žemlička, M., Hijazi, F., Bernasconi, A. C., Ferrer, C., Lachman, E., Field, M., Mohan, Y., de Vries, F. K., Bultink, C. C., van Oven, J., Mutus, J. Y., Stockill, R., Gröblacher, S.

Superconducting quantum processors have made significant progress in size and computing potential. As a result, the practical cryogenic limitations of operating large numbers of superconducting qubits are becoming a bottleneck for further scaling. Du

An integrated microwave-to-optics interface for scalable quantum computing

Autor: Weaver, Matthew J., Duivestein, Pim, Bernasconi, Alexandra C., Scharmer, Selim, Lemang, Mathilde, van Thiel, Thierry C., Hijazi, Frederick, Hensen, Bas, Gröblacher, Simon, Stockill, Robert

Publikováno v: Nat. Nanotechnol. 19, 166-172 (2024)

Microwave-to-optics transduction is emerging as a vital technology for scaling quantum computers and quantum networks. To establish useful entanglement links between qubit processing units, several key conditions have to be simultaneously met: the tr
