Several noisy intermediate-scale quantum computations can be regarded as logarithmic-depth quantum circuits on a sparse quantum computing chip, where two-qubit gates can be directly applied on only some pairs of qubits. In this paper, we propose a method to efficiently verify such noisy intermediate-scale quantum computation. To this end, we first characterize small-scale quantum operations with respect to the diamond norm. Then by using these characterized quantum operations, we estimate the fidelity $\langle\psi_t|\hat{\rho}_{\rm out}|\psi_t\rangle$ between an actual $n$-qubit output state $\hat{\rho}_{\rm out}$ obtained from the noisy intermediate-scale quantum computation and the ideal output state (i.e., the target state) $|\psi_t\rangle$. Although the direct fidelity estimation method requires $O(2^n)$ copies of $\hat{\rho}_{\rm out}$ on average, our method requires only $O(D^32^{12D})$ copies even in the worst case, where $D$ is the denseness of $|\psi_t\rangle$. For logarithmic-depth quantum circuits on a sparse chip, $D$ is at most $O(\log{n})$, and thus $O(D^32^{12D})$ is a polynomial in $n$. By using the IBM Manila 5-qubit chip, we also perform a proof-of-principle experiment to observe the practical performance of our method.

[44] If $n$-qubit quantum operations are allowed, the efficient verification is trivially possible. Let $U$ be a unitary operator such that $|\psi_t\rangle=U|0^n\rangle$ for an ideal output state $|\psi_t\rangle$. We apply $U^†$ to a received state $\hat{\rho}$ and measure all qubits in the computational basis. Then, by estimating the probability of $0^n$ being observed, we can estimate the fidelity $\langle 0^n|U^†\hat{\rho}U|0^n\rangle$ between $|\psi_t\rangle$ and $\hat{\rho}$.

[45] For clarity, we use the notation $\hat{a}$ when the lowercase letter $a$ is a quantum state or quantum operation. On the other hand, for any uppercase letter $A$, we omit $\hat{\color{white}{a}}$ even if $A$ is a quantum state or quantum operation.
