Long-lived and multiplexed atom-photon entanglement interface with feed-forward-controlled readouts

open access: yesCommunications Physics, 2021
The quantum interface to generate entanglement between a flying photonic qubit and a stationary qubit is a key functionality for the quantum internet. The authors demonstrate a multiplexed quantum interface that stores three long-lived spin-wave qubits ...

A Key Verification Protocol for Quantum Key Distribution [PDF]

open access: yesIEEE Access, 2019
Sharing a secret key between two physically separated nodes, Alice and Bob, is possible through the use of quantum key distribution (QKD) techniques. In the presence of an eavesdropper, Alice's key may not be identical with Bob's key, due to the characteristics of a quantum channel.

Chaotic Quantum Key Distribution [PDF]

open access: yesCryptography, 2020
The ability to send information securely is a vital aspect of today’s society, and with the developments in quantum computing, new ways to communicate have to be researched. We explored a novel application of quantum key distribution (QKD) and synchronized chaos which was utilized to mask a transmitted message. This communication scheme is not hampered

Layered quantum key distribution [PDF]

open access: yesPhysical Review A, 2018
We introduce a family of QKD protocols for distributing shared random keys within a network of $n$ users. The advantage of these protocols is that any possible key structure needed within the network, including broadcast keys shared among subsets of users, can be implemented by using a particular multi-partite high-dimensional quantum state.

Noiseless photonic non-reciprocity via optically-induced magnetization

open access: yesNature Communications, 2021
Optical nonreciprocity through magneto-optical effects requires bulky apparatuses and strong magnetic fields, while magnetic-free approaches are difficult to implement. Here, the authors use optically-induced magnetisation in an atomic ensemble to get 50

SECURITY OF QUANTUM KEY DISTRIBUTION [PDF]

open access: yesInternational Journal of Quantum Information, 2008
Quantum Information Theory is an area of physics which studies both fundamental and applied issues in quantum mechanics from an information-theoretical viewpoint. The underlying techniques are, however, often restricted to the analysis of systems which satisfy a certain independence condition.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
