Four- and six-photon stimulated Raman transitions for coherent qubit and qudit operations
Gabriel J. Gregory, Evan R. Ritchie, Alex Quinn +4
Quantum computers are typically composed of an array of two-level systems, or qubits, encoded in some information carrier, such as an electron, photon, or quantized circuit. The si…
Entanglement fidelity limits of photonically-networked atomic qubits from recoil and timing
Yichao Yu, Sagnik Saha, Mikhail Shalaev +5
The remote entanglement of two atomic quantum memories through photonic interactions is accompanied by atomic momentum recoil. When the interactions occur at different times, such…
Photonic Networking of Quantum Memories in High-Dimensions
Mikhail Shalaev, Sagnik Saha, George Toh +6
Quantum networking enables the exchange of quantum information between physically separated quantum systems, which has applications ranging from quantum computing to unconditionall…
Fast photon-mediated entanglement of continuously-cooled trapped ions for quantum networking
Jameson O'Reilly, George Toh, Isabella Goetting +8
We entangle two co-trapped atomic barium ion qubits by collecting single visible photons from each ion through in-vacuo 0.8 NA objectives, interfering them through an integrated fi…
High-fidelity remote entanglement of trapped atoms mediated by time-bin photons
Sagnik Saha, Mikhail Shalaev, Jameson O'Reilly +5
Photonic interconnects between quantum processing nodes are likely the only way to achieve large-scale quantum computers and networks. The bottleneck in such an architecture is the…
