Superconducting device develops continuous-variable quantum computing
A superconducting device has been reported that implements continuous-variable quantum computing, an approach usually associated with photonic systems. The work was published by Quantum Zeitgeist and appears to originate from a Brazilian federal university.

If the superconducting continuous-variable device can be integrated with existing circuit-QED control electronics, it could enable hybrid discrete-variable/continuous-variable processors on the same chip within two years.
Superconducting continuous-variable encodings use microwave resonators and Josephson junctions, the same physical platform as transmon qubits. Fabrication and readout infrastructure already exist in many labs, so the main near-term barrier is coherent control and state preparation for continuous-variable modes.
