Requirements for fault-tolerant factoring on an atom-optics quantum computer
Simon J. Devitt, Ashley M. Stephens, William J. Munro +1
Quantum information processing and its associated technologies has reached an interesting and timely stage in their development where many different experiments have been performed…
Fundamental limit to Qubit Control with Coherent Field
Kazuhiro Igeta, Nobuyuki Imoto, Masato Koashi
The ultimate accuracy as regards controlling a qubit with a coherent field is studied in terms of degradation of the fidelity by employing a fully quantum mechanical treatment. Whi…
A monolithically integrated polarization entangled photon pair source on a silicon chip
Nobuyuki Matsuda, Hanna Le Jeannic, Hiroshi Fukuda +6
Integrated photonic circuits are one of the most promising platforms for large-scale photonic quantum information systems due to their small physical size and stable interferometer…
Path Selection for Quantum Repeater Networks
Rodney Van Meter, Takahiko Satoh, Thaddeus D. Ladd +2
Quantum networks will support long-distance quantum key distribution (QKD) and distributed quantum computation, and are an active area of both experimental and theoretical research…
Discrete Fourier-based Correlations for Entanglement Detection
Ryo Namiki, Yuuki Tokunaga
We introduce two forms of correlations on two -level (qudit) systems for entanglement detection. The correlations can be measured via experimentally tractable two local measurem…
Entangling homogeneously broadened matter qubits in the weak-coupling cavity-QED regime
Kazuki Koshino, Yuichiro Matsuzaki
In distributed quantum information processing, flying photons entangle matter qubits confined in cavities. However, when a matter qubit is homogeneously broadened, the strong-coupl…
