Dear all,
Next Tuesday's talk will be in the Pauli Room at 5pm by Shun Watanabe.

Title:
Tomography increases key rates of quantum key distribution protocols
Abstract:
We construct a practically implementable classical processing for the
BB84 protocol and the six-state protocol that fully utilizes the
accurate channel estimation method, which is also known as the quantum
tomography. Our proposed processing yields at least as high key rate
as the standard processing by Shor and Preskill.…
[View More] We show two examples
of quantum channels over which the key rate of our proposed processing
is strictly higher than the standard processing. In the second
example, the BB84 protocol with our proposed processing yields a
positive key rate even though the so-called error rate is higher than
the 25% limit.

Dear All,
This weeks research day on Tuesday will be at the Electrical Engineering
Builidng, room ETF C109. The room will be opened at 9:30 am by Patrick
so we can work there the whole day.
There won't be a talk.
Cheers,
Dejan
