News › »FastGhost« • deve­lops a new micro­scope for quan­tum imaging

A rese­arch pro­ject fun­ded by the Euro­pean Union with about 3 mil­lion Euro is dedi­ca­ted to the deve­lo­p­ment of a che­mi­cally selec­tive micro­scope based on quan­tum tech­no­logy (quan­tum ghost ima­ging). The »FastGhost« pro­ject star­ted with a kick­off event on Octo­ber 20, 2020.

Quan­tum ima­ging with non-clas­si­cally cor­re­la­ted pho­ton pairs has fun­da­men­tal advan­ta­ges over con­ven­tio­nal ima­ging moda­li­ties based on clas­si­cal light: This inclu­des the pos­si­bi­lity of achie­ving high image qua­lity even with a very low num­ber of pho­tons. Fur­ther­more, the sam­ple inter­ac­tion and the spa­tial detec­tion on dif­fe­rent wav­elengths chan­nels are rele­vant advan­ta­ges of quan­tum ima­ging. This quan­tum tech­no­logy enab­les par­ti­cu­larly high-con­trast and infor­ma­tion-rich ima­ging of tis­sue with low radia­tion dose. Thus, it has a high poten­tial for app­li­ca­tion in life sci­en­ces. So far, howe­ver, the results are only avail­able theo­re­ti­cally and at the level of principle demonstrations.

The »FastGhost« pro­ject now aims to trans­late quan­tum ghost ima­ging from an expe­ri­men­tal approach into usable tech­no­logy. The aim is to deve­lop and imple­ment a micro­scope using the advan­ta­ges of non-clas­si­cal quan­tum sta­tes of light. This is inten­ded to demons­trate quan­tum ima­ging in the mid-infra­red range (»MIR«) with a wav­elength of up to 7 μm, a spa­tial reso­lu­tion of at least 5 μm, and at least 512 x 512 image pixels. It aims at taking no more than a second to take a sin­gle picture.

Such a micro­scope is a bre­akthrough for quan­tum ima­ging tech­no­logy, but also for a variety of important app­li­ca­ti­ons. The novel quan­tum micro­scopy can thus con­tri­bute to fully explo­i­t­ing the quan­tum advan­ta­ges. Howe­ver, various sci­en­ti­fic and tech­no­lo­gi­cal inno­va­tions are requi­red for the imple­men­ta­tion of the micro­scope – inclu­ding the deve­lo­p­ment of effi­ci­ent sin­gle-pho­ton detec­tors in the mid-infra­red range and fast sin­gle-pho­ton came­ras for cor­re­la­tion mea­su­re­ments. The part­ners of the »FastGhost« pro­ject will rese­arch these goals by 2023.
