Entanglement between superconducting qubits on distant chips is generated deterministically using shaped single microwave photons through a coaxial line acting as a direct quantum channel. P.

We use cryogenic systems to cool our electronic devices to close to absolute zero of temperature. The photograph shows a detail of one of our setups.

Research is done by an international team including PostDocs PhD and undergraduate students. The lab is supported by a project manager, technicians and a secretary.

We have realized the first quantum coherent communication protocol operated between superconducting quantum circuits located in two cryogenic systems separated by a distance of five meters.
