Deterministic nanofabrication for engineering nanowire quantum dot devices
Tarun Patel, Matteo Pennacchietti, Greg Holloway +8
Semiconductor quantum dots (QDs) are a leading platform for realising bright, wavelength-tunable sources of single and entangled photon pairs for photonic quantum technologies. Sit…
A Broadband Nanowire Quantum Dot Cavity Design for the Efficient Extraction of Entangled Photons
Sayan Gangopadhyay, Sasan V. Grayli, Sathursan Kokilathasan +1
A bright source of on-demand entangled photons is needed for quantum networks. A single quantum dot in a site-selected nanowire waveguide is a promising candidate for realizing suc…
Oscillating photonic Bell state from a semiconductor quantum dot for quantum key distribution
Matteo Pennacchietti, Brady Cunard, Shlok Nahar +10
An on-demand source of bright entangled photon pairs is desirable for quantum key distribution (QKD) and quantum repeaters. The leading candidate to generate entangled photon pairs…
Controlled Quantum Teleportation in the Presence of an Adversary
Sayan Gangopadhyay, Tiejun Wang, Atefeh Mashatan +1
We present a device independent analysis of controlled quantum teleportation where the receiver is not trusted. We show that the notion of genuine tripartite nonlocality allows us…
Simulating quantum chaos on a quantum computer
Amit Anand, Sanchit Srivastava, Sayan Gangopadhyay +1
We show that currently available noisy intermediate-scale quantum (NISQ) computers can be used for versatile quantum simulations of chaotic systems. We introduce a novel classical-…
Revealing Incommensurability between Device-Independent Randomness, Nonlocality, and Entanglement using Hardy and Hardy-type Relations
Souradeep Sasmal, Ashutosh Rai, Sayan Gangopadhyay +2
A comprehensive treatment of the quantification of randomness certified device-independently by using the Hardy and Cabello-Liang-Li (CLL) nonlocality relations is provided in the…
