Single and double quantum transitions in spin-mixed states under photo-excitation
Anand Patel, Zainab Chowdhry, Anil Prabhakar +2
Electronic spins associated with the Nitrogen-Vacancy (NV) center in diamond offer an opportunity to study spin-related phenomena with extremely high sensitivity owing to their hig…
Explicit attacks on differential phase shift quantum key distribution
Valliamai Ramanathan, Anil Prabhakar, Prabha Mandayam
In the well-established framework of quantum key distribution (QKD), differential phase shift (DPS) protocols have known information-theoretic security bounds defining tolerable er…
QKD in the NISQ era: enhancing secure key rates via quantum error correction
Shashank Kumar Ranu, Anil Prabhakar, Prabha Mandayam
Error mitigation is one of the key challenges in realising the full potential of quantum cryptographic protocols. Consequently, there is a lot of interest in adapting techniques fr…
3G R&D: R&D for the Next Generation of Ground-based Gravitational-wave Detectors
David McClelland, Harald Lueck, Rana Adhikari +43
To deliver on the promise of next generation gravitational-wave observatories, a sustained and coordinated detector research and development program is required. This report examin…
A spatial-photonic Ising machine to solve the two-way number-partitioning problem
Vikram Ramesh, Vighnesh Natarajan, Anil Prabhakar
We evaluate the performance of different algorithms in minimizing the Hamiltonian of a spatial-photonic Ising machine (SPIM). We then encode the number-partitioning problem on the…
Gated InGaAs Detector Characterization with Sub-Picosecond Weak Coherent Pulses
Gautam Kumar Shaw, Shyam Sridharan, Anil Prabhakar
We propose and demonstrate a method to characterize a gated InGaAs single-photon detector (SPD). Ultrashort weak coherent pulses, from a mode-locked sub-picosecond pulsed laser, we…
