Abstract Background Mycobacterium obuense (M. obuense) is a rapidly growing mycobacterium (RGM) which has been considered nonpathogenic. Here, we report a case of disseminated non-tuberculous mycobacterial (NTM) infection caused by M. obuense in an i

Abstract Background Nivolumab, an immune checkpoint inhibitor (ICI), has changed the treatment paradigm for advanced non‐small cell lung cancer (NSCLC). However, factors associated with long‐term survival in NSCLC patients treated with ICIs remai

In this study, we propose a method for predicting the occurrence of brittle fractures in the beam-to-column joints of steel structures, considering different crack opening modes. We conducted experiments on beam-to-diaphragm joint specimens with vary

Abstract Quantum key distribution (QKD) offers a reliable solution to communication problems that require long-term data security. For its widespread use, however, the rate and reach of QKD systems must be improved. Twin-field (TF) QKD is a step forw

Storage-free quantum repeaters represent a viable alternative to quantum-memory-based ones. Here, the authors propose a modified scheme for Bell state measurements which reduces the necessary resources for realising such an all-photonic repeater, and

In this paper, the shear strength of circular reinforced concrete (RC) columns was obtained using numerical models based on a modified compression field theory that enabled the sectional analysis of the beams. By comparing the computational results w

In a future quantum internet, entanglement or a secret key should be efficiently provided between two points via intermediate nodes connected by optical channels. Here the authors derive general rate-loss trade-off for such protocols, that is applica

Beating the repeaterless bound with adaptive measurement-device-independent quantum key distribution

New Journal of Physics, Vol 21, Iss 11, p 113052 (2019)
Surpassing the repeaterless bound is a crucial task on the way towards realizing long-distance quantum key distribution. In this paper, we focus on the protocol proposed by Azuma et al (2015 Nat. Commun. 6 10171), which can beat this bound with ideal

We provide a versatile upper bound on the number of maximally entangled qubits, or private bits, shared by two parties via a generic adaptive communication protocol over a quantum network when the use of classical communication is not restricted. Alt
