Terminal-Register Certification for Finite-Measurement Learning of Multiscale Quantum States
Bhvain Makwana, Kashyap Patel, Manjunath Joshi +1
Structured quantum-state learning not only depends on an expressive ansatz but also on an operational certificate that stays meaningful with finite measurements and imperfect imple…
One-Shot and Concurrent Hitting Times for Grover-Coined Quantum Walks on Cubelike Graphs
Jaideep Mulherkar
We study the one-shot and concurrent hitting for the discrete-time Grover-coined quantum walk on cubelike graphs of degree . Starting from th…
Quantum simulation of perfect state transfer on weighted cubelike graphs
Jaideep Mulherkar, Rishikant Rajdeepak, V. Sunitha
A continuous-time quantum walk on a graph evolves according to the unitary operator , where is the adjacency matrix of the graph. Perfect state transfer (PST) in a qu…
Perfect State Transfer in Weighted Cubelike Graphs
Jaideep Mulherkar, Rishikant Rajdeepak, V. Sunitha
A continuous-time quantum random walk describes the motion of a quantum mechanical particle on an underlying graph. The graph itself is associated with a Hilbert space of dimension…
Implementation of hitting times of discrete time quantum random walks on Cubelike graphs
Jaideep Mulherkar, Rishikant Rajdeepak, V Sunitha
We demonstrate an implementation of the hitting time of a discrete time quantum random walk on cubelike graphs using IBM's Qiskit platform. Our implementation is based on efficient…
Capacity of a quantum memory channel correlated by matrix product states
Jaideep Mulherkar, V. Sunitha
We study the capacity of a quantum channel where channel acts like controlled phase gate with the control being provided by a one-dimensional quantum spin chain environment. Due to…
Classical capacity of a qubit depolarizing memory channel with Markovian correlated noise
Jaideep Mulherkar
We study the classical capacity of a forgetful quantum memory channel that switches between two qubit depolarizing channels according to an ergodic Markov chain. The capacity of th…
