The quantum processors made at Chalmers University of Technology are engineered of superconducting qubits, in the form of electrical circuits on a microchip that can host quantum states of single photons. Operation of the quantum processor must take place in a cryostat, close to absolute zero temperature, so that the circuits are superconducting, thus conducting current without resistance. Linking many qubits is relatively easy, but controlling quantum states and performing error correction is difficult. The researchers are now learning to master their first-generation quantum computer built up of three qubits.
