Generic quantum walk using a coin-embedded shift operator
C. M. Chandrashekar
The study of quantum walk processes has been widely divided into two standard variants, the discrete-time quantum walk (DTQW) and the continuous-time quantum walk (CTQW). The conne…
Direct observation of quantum criticality in Ising spin chains
Jingfu Zhang, Fernando M. Cucchietti, C. M. Chandrashekar +6
We use NMR quantum simulators to study antiferromagnetic Ising spin chains undergoing quantum phase transitions. Taking advantage of the sensitivity of the systems near criticality…
Symmetry-noise interplay in quantum walk on an n-cycle
Subhashish Banerjee, R. Srikanth, C. M. Chandrashekar +1
Augmenting the unitary transformation which generates a quantum walk by a generalized phase gate G is a symmetry for both noisy and noiseless quantum walk on a line, in the sense t…
