Non-Gaussian state generation with time-gated photon detection

Tatsuki Sonoyama, Kazuma Takahashi, Baramee Charoensombutamon +9

Non-Gaussian states of light, which are essential in fault-tolerant and universal optical quantum computation, are typically generated by a heralding scheme using photon detectors.…

Experimental quantum data locking

Yang Liu, Zhu Cao, Cheng Wu +13

Classical correlation can be locked via quantum means--quantum data locking. With a short secret key, one can lock an exponentially large amount of information, in order to make it…

Towards joint reconstruction of noise and losses in quantum channels

F. Piacentini, A. Avella, P. Traina +7

The calibration of a quantum channel, i.e. the determination of the transmission losses affecting it, is definitely one of the principal objectives in both the quantum communicatio…

Quantum receiver beyond the standard quantum limit of coherent optical communication

Kenji Tsujino, Daiji Fukuda, Go Fujii +4

The most efficient modern optical communication is known as coherent communication and its standard quantum limit (SQL) is almost reachable with current technology. Though it has b…

Sub-shot-noise-limit discrimination of on-off keyed coherent signals via a quantum receiver with a superconducting transition edge sensor

Kenji Tsujino, Daiji Fukuda, Go Fujii +4

We demonstrate a sub-shot-noise-limit discrimination of on-off keyed coherent signals by an optimal displacement quantum receiver in which a superconducting transition edge sensor…
