A focused ion beam can pick up quantum emission from uncorrelated light
A research team at KAIST has developed a new technique using a focused ion beam that can increase single-photon purity levels. This technique can be applied to diverse quantum photonic platforms when a quantum emitter lacks single-photon purity....read more

Polaritonic PT symmetric laser in a single microcavity, lowering the threshold energy despite an increase the loss
A KAIST research team led by Professor Yong-Hoon Cho of the Department of Physics develops a new concept of what is termed a parity-time reversal (PT) symmetric laser with highly interactive quantum particles formed in a single microcavity system, improving the lasing performance despite an increase in the loss. The PT symmetric laser developed through this research is expected to be widely applied in areas ranging from classical photonic component with enhanced performance to quantum optical devices in the future....read more
