• Cryogenic on-wafer prober determines quality of qubit devices for quantum computing and quantum sensing

    Updated: 2023-08-31 19:41:03
    Germany's first cryogenic measuring setup for statistical quality measurement of qubit devices on whole 200- and 300-mm wafers has started operation at Fraunhofer IAF. The on-wafer prober can characterize devices based on semiconductor quantum dots and quantum wells as well as superconductors at measurement temperatures below 2 K.

  • Paving the way for advanced quantum sensors

    Updated: 2023-08-30 18:09:50
    Quantum physics has allowed for the creation of sensors far surpassing the precision of classical devices. Now, several new studies show that the precision of these quantum sensors can be significantly improved using entanglement produced by finite-range interactions. Researchers were able to demonstrate this enhancement using entangled ion-chains with up to 51 particles.
