Massachusetts Institute of Technology (MIT) researchers have unveiled a quantum computing architecture that performs low-error computations while rapidly sharing quantum data between processors.

Key to this was the construction of "giant atoms" from superconducting quantum bits (qubits), linked in a tunable configuration to a waveguide.

This enables researchers to tune the strength of qubit-waveguide interactions to protect the qubits from decoherence, while conducting high-fidelity operations. \

Once those computations are completed, the strength of the qubit-waveguide parings is readjusted, allowing the qubits to emit quantum data into the waveguide as photons. MIT's Bharath Kannan said, "The tricks we employed are relatively simple and, as such, one can imagine using this for further applications without a great deal of additional overhead."
