    "abstract": "A photon detector combining the two avalanche photon diodes (APD) has been\ndemonstrated for qubit discrimination in 1550 nm. Spikes accompanied with the\nsignals in gated-mode were canceled by balanced output from the two APDs. The\nspike cancellation enabled one to reduce the threshold in the discriminators,\nand thus the gate pulse voltage. The dark count probability and afterpulse\nprobability were reduced to 7x10^-7 and 10^-4, respectively, without affecting\nthe detection efficiency (11 %) at 178 K.",
