Spacetime mitigation of logical errors

Error detection can suppress noise at a lower sampling cost than probabilistic error cancellation (PEC), but leaves residual logical errors. We combine the two approaches to mitigate these errors while lowering the cost of PEC. We introduce a spacetime Pauli-Lindblad representation and use it to construct the post-sele...

Sampling hard circuits with verifiably high fidelity

The construction is a systematic method for promoting a stabilizer state to a magic state while keeping an error-detected fidelity certificate, and is a systematic method for promoting a stabilizer state to a magic state while keeping an error-detected fidelity certificate.

Sampling hard circuits with verifiably high fidelity

Sampling-based proposals are prominent candidates for demonstrating quantum computations beyond the reach of classical supercomputers. However, it has been difficult to combine their complexity-theoretic hardness with two capabilities needed for scalable quantum computing more generally: suppressing hardware errors, an...
