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.…
Resource-efficient Generalized Quantum Subspace Expansion
Bo Yang, Nobuyuki Yoshioka, Hiroyuki Harada +5
Realizing practical quantum computing requires overcoming a number of computation errors and the limitation of device size, which have intensively been tackled by quantum error mit…
Virtual quantum error detection
Kento Tsubouchi, Yasunari Suzuki, Yuuki Tokunaga +2
Quantum error correction and quantum error detection necessitate syndrome measurements to detect errors. Performing syndrome measurements for each stabilizer generator can be a sig…
Quantum error mitigation for rotation symmetric bosonic codes with symmetry expansion
Suguru Endo, Yasunari Suzuki, Kento Tsubouchi +4
The rotation symmetric bosonic code (RSBC) is a unified framework of practical bosonic codes that have rotation symmetries, such as cat codes and binomial codes. While cat codes ac…
Optimal cavity design for minimizing errors in cavity-QED-based atom-photon entangling gates with finite temporal duration
Takeru Utsugi, Rui Asaoka, Yuuki Tokunaga +1
We investigate atom-photon entangling gates based on cavity quantum electrodynamics (QED) for a finite photon-pulse duration, where not only the photon loss but also the temporal m…
