Abstract

We present a novel InGaAs/InAlAs single-photon avalanche diodes array with a triple- mesa structure. High photon detection efficiency of 36% with decent dark count rate of 1.9×107 Hz is achieved at 240 K.

Abstract

We realize a time-bin qudit-based quantum key distribution system that uses two-photon interference for measuring the phase-basis states, allowing us to generate a secret key at a megabits-per-second rate.

Abstract

We demonstrate a setup for realizing a four-dimensional time-frequency quantum key distribution protocol, where discrete temporal states are secured using discrete frequency states. The high-dimensional frequency states are detected using a tree of passively stabilized time-delay interferometers.

Abstract

We restrict quantum error correcting code sizes in third-generation quantum repeaters to explore qubit channel multiplexing. We find that the single link optimization is not necessarily the optimal configuration for improving the practical encoded-qubit throughput.
