Quantum key distribution based on private states: unconditional security over untrusted channels with zero quantum capacity

open access: yes, 2007
We prove unconditional security for a quantum key distribution (QKD) protocol based on distilling pbits (twisted ebits) [quant-ph/0309110] from an arbitrary untrusted state that is claimed to contain distillable key. Our main result is that we can verify

Effect and Compensation of Polarization‐Dependent Loss in Free‐Space Reference Frame Independent Quantum Key Distribution

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 3, March 2025.
This study addresses polarization‐dependent loss (PDL) in free‐space reference frame independent quantum key distribution (RFI QKD) systems, proposing a method to mitigate its effects. The method effectively compensates fidelity of polarization states, achieving a 94.01% secret key rate with 5 dB PDL.
