  "abstract": "It is well known that Grover's algorithm asymptotically transforms an equal superposition state into an eigenstate (of a given basis). Here, we demonstrate a verification algorithm based on weak measurement which can achieve the same purpose even if the qubit is \\textit{not} in an equal superposition state. The proposed algorithm highlights the \\textit{distinguishability} between any arbitrary single qubit superposition state and an eigenstate. We apply this algorithm to propose the scheme of a Quantum Locker, a protocol in which any legitimate party can verify his/her authenticity by using a newly developed Quantum One-Time Password (OTP) and retrieve the necessary message from the locker. We formally explicate the working of Quantum Locker in association with the Quantum OTP, which theoretically offers a much higher security against any adversary, as compared to any classical security device.",
