Limits for molecular spectroscopy from quantum channel discrimination
Anirban Dey, Akib Karim, Pieter Kok +2
Absorption spectroscopy identifies molecules by detecting frequency-dependent optical loss, and its fundamental limit is a quantum channel-discrimination problem. In this work, we…
All-electron hyperfine coupling of Si-, Ge- and Sn-vacancy defects in diamond
Akib Karim, Harish H. Vallabhapurapu, Chris Adambukulam +3
Colour centres in diamond are attractive candidates for numerous quantum applications due to their good optical properties and long spin coherence times. They also provide access t…
Bright photoluminescence of NV+ in diamond
Akib Karim, Igor Lyskov, Salvy P. Russo +1
The positively charged nitrogen vacancy (NV+) centre in diamond has been traditionally treated as a dark state due to the experimental lack of an optical signature. Recent computat…
An effective solid state photoluminescence by frequency constraint of cluster calculation
Akib Karim, Igor Lyskov, Salvy P. Russo +1
Measuring the photoluminescence of defects in crystals is a common experimental technique for analysis and identification. However, current theoretical simulations typically requir…
Beating the Classical Limits of Information Transmission using a Quantum Decoder
Robert J. Chapman, Akib Karim, Zixin Huang +3
Encoding schemes and error-correcting codes are widely used in information technology to improve the reliability of data transmission over real-world communication channels. Quantu…
High-dimensional entanglement certification
Zixin Huang, Lorenzo Maccone, Akib Karim +3
Quantum entanglement is the ability of joint quantum systems to possess global properties (correlation among systems) even when subsystems have no definite individual property. Whi…
Near orthogonal launch of SPR modes in Au films
John Canning, Akib Karim, Nikki Tzoumis +3
We report the excitation of a surface plasmon resonance (SPR) close to the orthogonal axis of a gold (Au) film on borosilicate glass. Direct spectroscopic measurement of SPR shifts…
