Quantum Magic in Discrete-Time Quantum Walk
Vikash Mittal, Yi-Ping Huang
Quantum magic, which accounts for the non-stabilizer content of a state, is essential for universal quantum computation beyond classically simulable resources. We investigate the g…
Discrete time quantum walk of locally interacting walkers
Vikash Mittal, Tomasz SowiÅski
In this work, we introduce a general form of a two-parameter family of local interactions between quantum walkers conditioned on the internal state of their coins. By choosing thei…
Deterministic generation of hybrid entangled states using quantum walks
Jaskaran Singh, Vikash Mittal, Soumyakanti Bose
In recent times, hybrid-entanglement (HE) between a qubit and a coherent state has demonstrated superior performance in various quantum information processing tasks, particularly i…
Parrondo's paradox in quantum walks with inhomogeneous coins
Vikash Mittal, Yi-Ping Huang
Parrondo's paradox, a counterintuitive phenomenon where two losing strategies combine to produce a winning outcome, has been a subject of interest across various scientific fields,…
