Ful­ly inte­gra­ted quantum magne­tic field sensor brings rea­ding of human mus­cle signals wit­hin reach

Stutt­gart, April 11, 2023 – Small, light­weight and high­ly sen­si­ti­ve: with a magne­tic field sensor the size of the palm of a hand, Stutt­gart-based start-up Q.ANT wants to open up industrial fiel­ds of app­li­ca­ti­on. One could be medi­cal technology. In the near future, the quantum sensor should be able to con­trol prosthe­ses via mus­cle signals. Poten­ti­al part­ners and inte­res­ted par­ties can find out more about this inno­va­ti­ve technology at the Han­no­ver Mes­se from April 17 in Hall 2, Stand C61

Along­side quantum com­pu­ting, quantum sen­sing is seen as a techno­logical pro­mi­se for the future. It could acce­le­ra­te industrial pro­gress and make things pos­si­ble that are at best known from sci­ence fic­tion movies. The Q.ANT magne­to­me­ter is a step in this direc­tion. It enab­les the mea­su­re­ment of the smal­lest magne­tic fiel­ds in the ran­ge of 300 picotes­la, and this at room tem­pe­ra­tu­re. Until now, this sen­si­ti­vi­ty ran­ge could only be achie­ved by coo­ling sensor systems to abso­lu­te zero at ‑273 °C or by hea­ting them up to 150 °C. As a result, sys­temic inte­gra­ti­on in industrial app­li­ca­ti­ons was har­dy feasible. 

In con­trast, Q.ANT’s magne­tic field sensor achie­ves the high sen­si­ti­vi­ty at room tem­pe­ra­tu­re and paves the way to app­li­ca­ti­ons sui­ta­ble for ever­y­day use. This is the first time that a ful­ly inte­gra­ted dia­mond-based quantum sensor is advan­cing into are­as whe­re the detec­tion of mus­cle signals beco­mes rea­listic. The cor­re­spon­ding pro­of has alrea­dy been pro­vi­ded with a labo­ra­to­ry set­up. Three to four years of development work are still nee­ded befo­re the technology is rea­dy for app­li­ca­ti­on. Then, magne­tic field sensors built into prosthe­ses will be able to detect mus­cle signals and trig­ger cor­re­spon­ding move­ments. In this way, a prost­he­tic hand could clo­se into a fist or reach for a cup. The sensors, inclu­ding the con­trol technology, are still too lar­ge to be inte­gra­ted into prosthe­ses. In the com­ing years, howe­ver, they should shrink from the size of a tin can to match­box size. 

Howe­ver, Q.ANT foun­der and CEO Micha­el Förtsch can also envi­si­on are­as of app­li­ca­ti­on in other industrial sec­tors that are alrea­dy being con­si­de­red, name­ly “whe­re­ver ultra-fine cur­r­ents need to be mea­su­red, such as in the elec­tro­nics indus­try for qua­li­ty con­trol of cir­cuit car­ri­ers or hard dri­ves, but also to iden­ti­fy fault cur­r­ents in power chips or bat­te­ries.” Other pos­si­ble app­li­ca­ti­ons are in medi­cal technology for ear­ly detec­tion of dise­a­ses in the brain, or loca­liz­a­ti­on app­li­ca­ti­ons in the auto­mo­ti­ve indus­try. Förtsch descri­bes the area of human-machi­ne inter­ac­tion as a “medi­um-term goal.” Quantum sensor technology makes many things con­ceiva­ble, inclu­ding the pos­si­bi­li­ty that machi­nes will one day be con­trol­led by thoughts. 

Q.ANT wants to demons­tra­te the poten­ti­al of its magne­tic field sensors for various industrial app­li­ca­ti­ons at the Han­no­ver Fair by means of a dis­play: an exhi­bit con­sis­ting of an arti­fi­cial hand made of glass, through which a weak cur­rent flows, and a quantum sensor. “We read the magne­tic field gene­ra­ted by the cur­rent from the demons­tra­tor without con­ta­ct. This allows the sensor to open and clo­se the prost­he­tic hand,” Förtsch exp­lains. With the tra­de fair appearan­ce, Q.ANT wants to draw the atten­ti­on of poten­ti­al industrial part­ners to the new technology — in order to then ide­al­ly deve­lop it fur­ther for a con­cre­te application. 

At the Han­no­ver Fair from April 17 to 21, Q.ANT will be pre­sent in Hall 2, Booth C61

About Q.ANT

Q.ANT is a high-tech start­up dri­ving quantum technology, foun­ded in 2018 and part of the TRUMPF Group. Q.ANT’s visi­on is to impro­ve the qua­li­ty of how machi­nes ana­ly­ze their envi­ron­ment, how humans noti­ce infor­ma­ti­on, and the way we think. To reach this visi­on, Q.ANT deve­lo­ps quantum sensors and quantum com­pu­ting chips based on its Quantum Pho­to­nic Frame­work. Focu­sing on its four pro­duct lines of Pho­to­nic Com­pu­ting, Par­ti­cle Metro­lo­gy, Ato­mic Gyro­scopes and Magne­tic Sen­sing, the com­pa­ny enga­ges with a broad array of indus­tries and app­li­ca­ti­ons ran­ging all the way from medi­cal technology and auto­no­mous vehi­cles to aero­space, machine­ry, and the pro­cess indus­try. Q.ANT employs more than 60 peop­le at its site in Stuttgart/Southern Germany.
