Entanglement Thresholds of Doubly Parametric Quantum Transducers

Author(s)
Curtis Rau, Akira Kyle, Alexander T. Kwiatkowski, Ezad Shojaee, John Teufel, Konrad Lehnert, Tasshi Dennis
Doubly parametric quantum transducers, such as electro-optomechanical devices, show promise for providing the critical link between quantum information encoded

High-fidelity indirect readout of trapped-ion hyperfine qubits

Author(s)
Stephen Erickson, Jenny Wu, Panyu Hou, Daniel Cole, Shawn Geller, Alexander Kwiatkowski, Scott Glancy, Emanuel Knill, Daniel Slichter, Andrew C. Wilson, Dietrich Leibfried
We propose and demonstrate a protocol for high-fidelity indirect readout of trapped ion hyperfine qubits, where the state of a 9Be+ qubit ion is mapped to a

High-fidelity laser-free universal control of trapped ion qubits

Author(s)
Raghavendra Srinivas, Emanuel Knill, Robert Sutherland, Alexander T. Kwiatkowski, Hannah M. Knaack, Scott Glancy, David J. Wineland, Shaun C. Burd, Dietrich Leibfried, Andrew C. Wilson, David T. Allcock, Daniel Slichter
Universal control of multiple qubits—the ability to entangle qubits and to perform arbitrary individual qubit operations—is a fundamental resource for quantum
