Fig. 2. Conditional teleportation of a classical spin state.

a Quantum circuit to teleport a state $∣\uparrow ⟩$ from qubit 1 to qubit 4. The conditional singlet–triplet measurement on qubits 1 and 2 induces teleportation, and the gray singlet–triplet measurement of the right pair verifies teleportation. b Experimentally measured probability distribution for 65,536 single-shot realizations of the teleportation sequence in a. The white cross indicates the threshold used to calculate probabilities. c Extracted probabilities p from the distribution in b. d Simulated probabilities computed neglecting any errors. e Simulated probabilities accounting for readout errors, state preparation errors, charge noise, and hyperfine fields. All probabilities are rounded to the nearest hundredth.
