＜正＞ Copper （Cu） is a highly promising alternative material to aluminum-based alloys for the next generation of ULSI circuits owing to its low electrical resistivity and high electromigration （EM） resistance. However, Cu line or film cannot completely show its advantage since Cu can easily diffuse to silicon （Si） substrate and the adhesion strength between Cu and Si is not well enough in some cases. It is well recognized that adding a diffusion barrier between Cu film and Si substrate can resolve the diffusion problem and improve adhesion

第十八届全国量子光学学术会议

As one of the important frontiers of quantum cryptography, quantum digital signatures（QDSs） have promising prospects in future applications. QDSs offer the information-theoretic security verified by quantum mechanics to send a message against forging and repudiation [1-3]. Here in this paper, we first report a proof-of-principle demonstration of a passive decoy-state QDS system, which can avoid leaking the modulation information of decoy states. To realize this, in our system, four local detection events are generated from the idler light of a parametric down-conversion（PDC） process, and then used as decoy states to estimate channel parameters more accurately [4]. As a result, we can successfully signed more than one-bit message within 7 seconds at 100 km. Besides, we can achieve the transmission distance over 200 km, which represents a further step towards the practical application of QDSs.
