This study demonstrates a significant leap in quantum communication capabilities by using optical cavities to boost photon interference visibility from the typical 60% to 90%. By manipulating the timing of photon emissions from quantum dots, researchers have overcome key coherence obstacles that previously hindered practical entangled photon pair generation. This advancement brings quantum dot-based sources closer to the performance thresholds required for viable quantum networks.
Device Raises Photon Interference to 90%

A new semiconductor boosts photon interference to 90%, edging quantum dots closer to practical quantum communication.
Timon Baltisberger from the University of Basel and colleagues at Ruhr University Bochum have achieved 90% photon interference visibility, a substantial jump from the typical 60% seen in quantum communication experiments. The team used an optical cavity to manipulate the timing of photon emissions from a quantum dot, demonstrating that accelerating the first photon improves coherence while accelerating the second has the opposite effect. “This is a process in which a quantum…
