A Quantum Algorithm for Random Number Generation
Aastha Kataria, Devansh Desai, Ashwini Dalvi +4
We present a quantum algorithm for random number generation that achieves a provable quadratic speedup over classical Markov chain mixing, building on the Diaconis-Shahshahani Four…
Crossover between the zeptosecond and attosecond physics
T. Nandi, Yash Kumar, Adya P. Mishra +7
Nuclear orbiting resonances have been revealed at the sub-barrier energies as an atomic phenomenon by means of x-ray spectroscopy experiments. This interpretation is supported by s…
PT-Symmetric -like Random Matrix Ensembles: Invariant Distributions and Spectral Fluctuations
Stalin Abraham, A. Bhagwat, Sudhir Ranjan Jain
We consider an ensemble of normal matrices with complex entries representing operators in the quantum mechanics of 2 - level parity-time reversal (PT) symmetric systems…
Controlling and engineering a quantum state in a multi-qubit system employing the quantum Zeno effect
Dhruva Naik, Garima Rajpoot, Sudhir Ranjan Jain
Controlling quantum jumps is crucial for reliable quantum computing. In this work, we demonstrate how the quantum Zeno effect can be applied to a two qubit system interacting with…
