FragQC: An Efficient Quantum Error Reduction Technique using Quantum Circuit Fragmentation
Saikat Basu, Arnav Das, Amit Saha +2
Quantum computers must meet extremely stringent qualitative and quantitative requirements on their qubits in order to solve real-life problems. Quantum circuit fragmentation techni…
Purifications Without Entanglement, State Reconstructions and Entropy
Chirag Dhara, N. D. Hari Dass
In this paper we have analysed in detail two different purification protocols. The first one, proposed by Sudarshan, is based on the preservation of probabilities.We have construct…
Purification of Single Qubits and reconstruction from Post-Measurement State
Chirag Dhara, N. D. Hari Dass
Purification of mixed states in Quantum Mechanics, by which we mean the transformation into pure states, has been viewed as an {\it Operation} in the sense of Kraus et al and expli…
Quantum and Classical Phase Space: Separability and Entanglement
Ajay Patwardhan
The formalism of classical and quantum mechanics on phase space leads to symplectic and Heisenberg group representations, respectively. The Wigner functions give a representation o…
Quantisation on general spaces
Ajay Patwardhan
Quantisation on spaces with properties of curvature, multiple connectedness and non orientablility is obtained. The geodesic length spectrum for the Laplacian operator is extended…
