Randomness can be certified in energy-constrained semi-device-independent scenarios
Shashank Kumar Ranu, Lewis Wooltorton, Alastair A. Abbott +1
The prepare-and-measure framework based on energy constraints offers a practical middle ground between fully device-dependent and device-independent quantum cryptography. The only…
Mitigating imperfections in Differential Phase Shift Measurement-Device-Independent Quantum Key Distribution via Plug-and-Play architecture
Nilesh Sharma, Shashank Kumar Ranu, Prabha Mandayam +1
Measurement-device-independent quantum key distribution (MDI-QKD) was originally proposed as a means to address the issue of detector side-channel attacks and enable finite secure…
Estimating Coherent Contributions to the Error Profile Using Cycle Error Reconstruction
Arnaud Carignan-Dugas, Shashank Kumar Ranu, Patrick Dreher
Mitigation and calibration schemes are central to maximize the computational reach of today's Noisy Intermediate Scale Quantum (NISQ) hardware, but these schemes are often speciali…
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…
Single magnon excited states of a Heisenberg spin-chain using a quantum computer
Shashank Kumar Ranu, Daniel D. Stancil
Excited states of spin-chains play an important role in condensed matter physics. We present a method of calculating the single magnon excited states of the Heisenberg spin-chain t…
Equivalence of space and time-bins in DPS-QKD
Gautam Shaw, Shyam Sridharan, Shashank Ranu +3
Key generation efficiency, and security, in DPS-QKD improve with an increase in the number of path delays or time-bin superpositions. We demonstrate the implementation of super-pos…
Differential phase encoded measurement-device-independent quantum key distribution
Shashank Kumar Ranu, Anil Prabhakar, Prabha Mandayam
We present a measurement-device-independent quantum key distribution (MDI-QKD) using single photons in a linear superposition of three orthogonal time-bin states, for generating th…
