| Exact computation of tail probability of hypergeometric distribution and its application to quantum key distribution | QCRYPT 2013 | Kenta Sakakibara, Ryutaroh Matsumoto |
Tomamichel and Renner improved the key rate of a Quantum Key Distributing (QKD) protocol with the finite number of qubits. To compute the key rate, we need to estimate a phase error rate, which obey a hypergeometric distribution. They did not compute directly the tail probability of the hypergeometric distribution to obtain the estimate of the error rate, and they used an upper bound on the tail probability that a phase error rate is larger than the estimate. We improve the key rate of the QKD by exact numerical computation of the tail probability. |
