BBOI gets ultra-high-performance quantum photonics

Ultra-high-performance quantum photonics 
The BBOI team at the University of Bristol has demonstrated ultra-high fidelity single-qubit operations on chip, by using additional optical degrees of freedom, showing bright light extinction ratios as high as 60 dB.

Separately, the team has shown ultra-high-extinction filters—capable of separating a bright laser beam from on-chip single photons. Future on-chip quantum photonics will rely on both advances to achieve the required performance.
