Linear optical Bell state measurement for rotation-symmetric cat codes
Issa Oe, Suguru Endo, Rui Asaoka
Rotation-symmetric cat (RS-cat) codes are a bosonic-code platform for quantum information processing, combining finite-energy realizability with robustness against photon loss thro…
Addressing requirements for crosstalk-free quantum-gate operation in many-body nanofiber cavity QED systems
Tim Keller, Seigo Kikura, Rui Asaoka +3
A distributed network architecture in which flying photons connect individual modules containing stationary atomic qubits is a promising approach for scaling up neutral-atom based…
Fault-tolerant logical state construction based on cavity-QED network
Rui Asaoka, Yasunari Suzuki, Yuuki Tokunaga
Exploring an efficient and scalable architecture of fault-tolerant quantum computing (FTQC) is vital for demonstrating useful quantum computing. Here, we propose and evaluate a sca…
High-purity single-photon generation based on cavity QED
Seigo Kikura, Rui Asaoka, Masato Koashi +1
We propose a scheme for generating a high-purity single photon on the basis of cavity quantum electrodynamics (QED). This scheme employs a four-level system including two excited s…
Speed Limit of Efficient Cavity-Mediated Adiabatic Transfer
Akinori Suenaga, Takeru Utsugi, Rui Asaoka +3
Cavity-mediated adiabatic transfer (CMAT) is a robust way to perform a two-qubit gate between trapped atoms inside an optical cavity. In the previous study by Goto and Ichimura [H.…
Stimulated emission of superradiant atoms in waveguide QED
Rui Asaoka, Julio Gea-Banacloche, Yuuki Tokunaga +1
We investigate the stimulated emission of superradiant atoms coupled to a waveguide induced by a coherent-state photon pulse. We provide an analytical result when a short pulse…
