![]() There is work to create space based starshades for large ground based telescopes. The light of the star would need to be shielded so we could see the exoplanet in detail. The next step, said Huang, is to couple the light with quantum error correction (QEC), a technique used in quantum computing to protect quantum information from errors due to decoherence and other “quantum noise.Īrxiv – Imaging Stars with Quantum Error Correction.Ĭombining the light from telescopes across the entire planet would enable direct imaging of planets in other solar systems. ![]() The process they envision would involve coherently coupling the starlight into “dark” atomic states that do not radiate. However, this task becomes very difficult in optical frequencies, because even the fastest electronics cannot directly measure the oscillations of the electric field at these frequencies. We can already do large-baseline interferometry in the microwave. In recent years, VLBI has yielded the most detailed images of the stars that orbit Sagitarrius A* (Sgr A*), the SMBH at the center of our galaxy. Very Long Baseline Interferometry refers to a specific technique used in radio astronomy where signals from an astronomical radio source (black holes, quasars, pulsars, star-forming nebulae, etc.) are combined to create detailed images of their structure and activity. The interferometry technique consists of combining light from multiple telescopes to create images of an object that would otherwise be too difficult to resolve. ![]() Once integrated with next-generation instruments, this technique could allow for more detailed studies of black holes, exoplanets, the Solar System, and the surfaces of distant stars. When imprinted into a quantum error correction code, this technique could allow for VLBI observations into previously inaccessible wavelengths. It’s known as Stimulated Raman Adiabatic Passage (STIRAP), which allows quantum information to be transferred without losses. Researchers from Australia and Singapore are working on a new quantum technique that could enhance optical VLBI.
