Quantum Data Bus in Dipolar Coupled Nuclear Spin Qubits
Jingfu Zhang, Michael Ditty, Daniel Burgarth +6
We implement an iterative quantum state transfer exploiting the natural dipolar couplings in a spin chain of a liquid crystal NMR system. During each iteration a finite part of the…
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…
Discrete time quantum walk model for single and entangled particles to retain entanglement in coin space
C. M. Chandrashekar
In most widely discussed discrete time quantum walk model, after every unitary shift operator, the particle evolves into the superposition of position space and settles down in one…
