Channel Simulation: Finite Blocklengths and Broadcast Channels
Michael X. Cao, Navneeth Ramakrishnan, Mario Berta +1
We study channel simulation under common randomness assistance in the finite-blocklength regime and identify the smooth channel max-information as a linear program one-shot convers…
Moderate deviation expansion for fully quantum tasks
Navneeth Ramakrishnan, Marco Tomamichel, Mario Berta
The moderate deviation regime is concerned with the finite block length trade-off between communication cost and error for information processing tasks in the asymptotic regime, wh…
Computing Quantum Channel Capacities
Navneeth Ramakrishnan, Raban Iten, Volkher B. Scholz +1
The capacity of noisy quantum channels characterizes the highest rate at which information can be reliably transmitted and it is therefore of practical as well as fundamental impor…
Equivalence of Effective Medium and Random Resistor Network models for disorder-induced unsaturating linear magnetoresistance
Navneeth Ramakrishnan, Ying Tong Lai, Silvia Lara +2
A linear unsaturating magnetoresistance at high perpendicular magnetic fields, together with a quadratic positive magnetoresistance at low fields, has been seen in many different e…
Transport and magnetotransport in 3D Weyl Semimetals
Navneeth Ramakrishnan, Mirco Milletari, Shaffique Adam
We theoretically investigate the transport and magnetotransport properties of three-dimensional Weyl semimetals. Using the RPA-Boltzmann transport scattering theory for electrons s…
Excitation of two atoms by a propagating single photon pulse
Navneeth Ramakrishnan, Yimin Wang, Valerio Scarani
We describe the interaction of two two-level atoms in free space with propagating modes of the quantized electromagnetic field, using the time-dependent Heisenberg-Langevin method.…
Disorder induced magnetoresistance in a two dimensional electron system
Jinglei Ping, Indra Yudhistira, Navneeth Ramakrishnan +3
We predict and demonstrate that a disorder induced carrier density inhomogeneity causes magnetoresistance (MR) in a two-dimensional electron system. Our experiments on graphene sho…
