 This is the first demonstration of quantum hacking against a non-homemade quantum key distribution system.Later on, the phase-remapping attack was also demonstrated on a specially configured, research oriented open QKD system (made and provided by the Swiss company Id Quantique under their Quantum Hacking program).It is one of the first ‘intercept-and-resend’ attacks on top of a widely used QKD implementation in commercial QKD systems.
