Quantum Journal Club: A near–quantum-limited Josephson traveling-wave parametric amplifier

Abstract: Detecting single–photon level signals—carriers of both classical and quantum information—is particularly challenging for low-energy microwave frequency excitations. Here we introduce a s...

Quantum Journal Club: Storage Enhanced Nonlinearities in a Cold Atomic Rydberg Ensemble

Abstract: The combination of electromagnetically induced transparency with the nonlinear interaction between Rydberg atoms provides an effective interaction between photons. In this Letter, we invest...

Entangling Coherent States into A Maximally Entangled Qudits and/or Qudit Cluster States

Abstract: Optically coherent states can be interpreted as qudits with arbitrary integer d. Weak cross-Kerr nonlinear interaction can maximally entangle two coherent states and this can be used for va...

Quantum Journal Club: Coherent and dynamic beam splitting based on light storage in cold atoms

Abstract: We demonstrate a coherent and dynamic beam splitter based on light storage in cold atoms. An input weak laser pulse is first stored in a cold atom ensemble via electromagnetically induced t...

Quantum Gate Operation in the Circuit-QED Lattice with Circulator Function

Abstract: We propose a scheme for a scalable quantum computing in the circuit-quantum electrodynamics(QED) architecture. In the Kagome lattice of qubits three qubits are connected to each other throu...
