Controlled dynamics of a multi-component discrete-time quantum walker
Vikash Mittal, Tomasz Sowiński
We investigate a discrete-time quantum walk of a three-component quantum particle on a one-dimensional lattice. As coin operators, we employ parameterized rotations generated by th…

Discrete time quantum walk of locally interacting walkers
Vikash Mittal, Tomasz Sowiński
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…

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…
