Permutation-equivariant quantum convolutional neural networks

no code implementations28 Apr 2024 Sreetama Das, Filippo Caruso

The $S_{n}$-equivariant QCNN architecture shows significantly improved training and test performance than non-equivariant QCNN for classification of connected and non-connected graphs.

The role of data embedding in equivariant quantum convolutional neural networks

no code implementations20 Dec 2023 Sreetama Das, Stefano Martina, Filippo Caruso

In this work, we investigate the role of classical-to-quantum embedding on the performance of equivariant quantum convolutional neural networks (EQCNNs) for the classification of images.

Experimental quantum pattern recognition in IBMQ and diamond NVs

no code implementations1 May 2022 Sreetama Das, Jingfu Zhang, Stefano Martina, Dieter Suter, Filippo Caruso

Here, we investigate the possibility of realizing a quantum pattern recognition protocol based on swap test, and use the IBMQ noisy intermediate-scale quantum (NISQ) devices to verify the idea.

Computer Vision-based Social Distancing Surveillance Solution with Optional Automated Camera Calibration for Large Scale Deployment

no code implementations22 Apr 2021 Sreetama Das, Anirban Nag, Dhruba Adhikary, Ramswaroop Jeevan Ram, Aravind BR, Sujit Kumar Ojha, Guruprasad M Hegde

In this paper, we discuss different metrics to assess the risk associated with social distancing violations and how we can differentiate between transient or persistent violations.

Three qubits in less than three baths: Beyond two-body system-bath interactions in quantum refrigerators

no code implementations15 Dec 2020 Ahana Ghoshal, Sreetama Das, Amit Kumar Pal, Aditi Sen De, Ujjwal Sen

We show that quantum absorption refrigerators, which have traditionally been studied as of three qubits, each of which is connected to a thermal reservoir, can also be constructed by using three qubits and two thermal baths, where two of the qubits, including the qubit to be locally cooled, are connected to a common bath.
