Kami menganggap ukuran yang tidak sepadan dalam protokol pengedaran kunci kuantum BB84, yang mana pangkalan pengukuran berbeza daripada pangkalan pemancar. Kami memberikan had yang lebih rendah pada jumlah kunci rahsia yang boleh diekstrak daripada ukuran yang tidak sepadan. Batasan bawah kami menunjukkan bahawa kami boleh mengekstrak kunci rahsia daripada ukuran yang tidak sepadan dengan saluran kuantum tertentu, seperti saluran di mana matriks Hadamard digunakan pada setiap qubit dengan kebarangkalian yang tinggi. Selain itu, prinsip ketidakpastian entropik membayangkan bahawa seseorang tidak boleh mengekstrak kunci rahsia daripada kedua-dua ukuran yang dipadankan dan yang tidak sepadan secara serentak, apabila kami menggunakan prosedur penyelarasan maklumat standard dan penguatan privasi.

Abstract: We consider the mismatched measurements in the BB84 quantum key distribution protocol, in which measuring bases are different from transmitting bases. We give a lower bound on the amount of a secret key that can be extracted from the mismatched measurements. Our lower bound shows that we can extract a secret key from the mismatched measurements with certain quantum channels, such as the channel over which the Hadamard matrix is applied to each qubit with high probability. Moreover, the entropic uncertainty principle implies that one cannot extract the secret key from both matched measurements and mismatched ones simultaneously, when we use the standard information reconciliation and privacy amplification procedure.

AB - We consider the mismatched measurements in the BB84 quantum key distribution protocol, in which measuring bases are different from transmitting bases. We give a lower bound on the amount of a secret key that can be extracted from the mismatched measurements. Our lower bound shows that we can extract a secret key from the mismatched measurements with certain quantum channels, such as the channel over which the Hadamard matrix is applied to each qubit with high probability. Moreover, the entropic uncertainty principle implies that one cannot extract the secret key from both matched measurements and mismatched ones simultaneously, when we use the standard information reconciliation and privacy amplification procedure.
