Integrated Conditional Teleportation and Readout Circuit Based on a Photonic Crystal Single Chip

摘要

We demonstrate the design of an integrated conditional quantum teleportationcircuit and a readout circuit using a two-dimensional photonic crystal singlechip. Fabrication and testing of the proposed quantum circuit can beaccomplished with current or near future semiconductor process technology andexperimental techniques. The readout part of our device, which has potentialfor independent use as an atomic interferometer, can also be used on its own orintegrated with other compatible optical circuits to achieve atomic statedetection. Further improvement of the device in terms of compactness androbustness could be achieved by integrating it with sources and detectors inthe optical regime.
