that are harmonic in nature. Now researchers may have found a way to use both electromagnetic qubits and mechanical resonators to create a hybrid form that acts like a mechanical qubit ...

The new mechanical qubit, however, uses phonons — a type ... energy in the form of phonons — are typically subject to harmonic vibrations at evenly spaced energy levels. This is an issue ...

To improve the situation, MIT researchers and researchers worldwide have continually focused on improving qubit performance. In new work, using a superconducting qubit called fluxonium ...

The quasi-phase-matched second harmonic signal surpasses the usual ... that uses a thermal gradient to reset a superconducting qubit more effectively than conventional methods.

In their experiments, Chen, Zhu and their colleagues used classical decoding to extract and stabilize the quantum order in their 54-qubit system that was masked by noise. They found that this ...
