#superconducting-qubits

Superconducting circuits, trapped ions, neutral atoms, photons, silicon spins and topological qubits compared: how each works, who builds it, and the trade-offs.

Follow one quantum circuit through the real machine: compiler, control electronics, cryostat, qubits, gates, readout, errors, shots and post-processing.

The inside of a quantum computer is about 270 times colder than outer space. Here's why heat destroys qubits, and why the machine looks like a giant chandelier.
