Benchmarking quantum key distribution by mixing single photons and laser light
Yann Portella, Petr Steindl, Juan Rafael Álvarez +8
Quantum key distribution is a key application of quantum mechanics, shaping the future of privacy and secure communications. Many protocols require single photons, often approximat…
Covert Quantum Communication Over Optical Channels
Evan J. D. Anderson, Christopher K. Eyre, Isabel M. Dailey +2
We explore covert communication of qubits over the lossy thermal-noise bosonic channel, which is a quantum-mechanical model of many practical channels, including optical. Covert co…
Key rates for quantum key distribution protocols with asymmetric noise
Gláucia Murta, Filip Rozpędek, Jérémy Ribeiro +2
We consider the asymptotic key rates achieved in the simplest quantum key distribution protocols, namely the BB84 and the six-state protocols, when non-uniform noise is present in…
Near-term quantum-repeater experiments with nitrogen-vacancy centers: Overcoming the limitations of direct transmission
Filip Rozpędek, Raja Yehia, Kenneth Goodenough +5
Quantum channels enable the implementation of communication tasks inaccessible to their classical counterparts. The most famous example is the distribution of secret key. However,…
Optimizing practical entanglement distillation
Filip Rozpędek, Thomas Schiet, Le Phuc Thinh +3
The goal of entanglement distillation is to turn a large number of weakly entangled states into a smaller number of highly entangled ones. Practical entanglement distillation schem…
Parameter regimes for a single sequential quantum repeater
Filip Rozpędek, Kenneth Goodenough, Jérémy Ribeiro +6
Quantum key distribution allows for the generation of a secret key between distant parties connected by a quantum channel such as optical fibre or free space. Unfortunately, the ra…
