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…
The quadratic speedup in Grover's search algorithm from the entanglement perspective
Pranaw Rungta
We analyze the role played by entanglement in the dynamical evolution of Grover's search algorithm in the space of qubits. We show that the algorithm can be equivalently described…
Quantum Random Walks without a Coin Toss
Apoorva Patel, K. S. Raghunathan, Pranaw Rungta
We construct a quantum random walk algorithm, based on the Dirac operator instead of the Laplacian. The algorithm explores multiple evolutionary branches by superposition of states…
Entanglement of Formation of an Arbitrary State of Two Rebits
Carlton M. Caves, Christopher A. Fuchs, Pranaw Rungta
We consider entanglement for quantum states defined in vector spaces over the real numbers. Such real entanglement is different from entanglement in standard quantum mechanics over…
