Using Quantum Switches to Mitigate Noise in Grover's Search Algorithm
Suryansh Srivastava, Arun K. Pati, Samyadeb Bhattacharya +1
Grover's quantum search algorithm promises a quadratic speedup for unstructured search over its classical counterpart. But this advantage is affected by noise acting on the search…
Quantifying the particle aspect of quantum systems
Sreetama Das, Indranil Chakrabarty, Arun Kumar Pati +2
The possibility of a quantum system to exhibit properties that are akin to both the classically held notions of being a particle and a wave, is one of the most intriguing aspects o…
No-masking theorem for observables
Swapnil Bhowmick, Abhay Srivastav, Arun Kumar Pati
The no-masking theorem for quantum information proves that it is impossible to encode an arbitrary input state into a larger bipartite entangled state such that the full informatio…
Effect of measurements on quantum speed limit
Abhay Srivastav, Vivek Pandey, Arun K Pati
Given the initial and final states of a quantum system, the speed of transportation of state vector in the projective Hilbert space governs the quantum speed limit. Here, we ask th…
