Simple coplanar waveguide resonator mask targeting metal-substrate interface
Cameron J. Kopas, Ella Lachman, Corey Rae H. McRae +4
This white paper presents a single-layer mask, found at https://github.com/Boulder-Cryogenic-Quantum-Testbed/simple-resonator-mask. It is designed for fabrication of superconductin…
Towards Automated Sexual Violence Report Tracking
Naeemul Hassan, Amrit Poudel, Jason Hale +4
Tracking sexual violence is a challenging task. In this paper, we present a supervised learning-based automated sexual violence report tracking model that is more scalable, and rel…
Resonant Energy Transfer Under the Influence of the Evanescent Field from the Metal
Amrit Poudel, Xin Chen, Mark A. Ratner
We present a quantum framework based on a density matrix of a dimer system to investigate the quantum dynamics of excitation energy transfer (EET) in the presence of the evanescent…
Enhancement of Resonant Energy Transfer Due to Evanescent-wave from the Metal
Amrit Poudel, Xin Chen, Mark A. Ratner
The high density of evanescent modes in the vicinity of a metal leads to enhancement of the near-field Förster resonant energy transfer (FRET) rate. We present a classical approach…
Dynamical generation of Floquet Majorana flat bands in s-wave superconductors
Amrit Poudel, Gerardo Ortiz, Lorenza Viola
We present quantum control techniques to engineer flat bands of symmetry-protected Majorana edge modes in s-wave superconductors. Specifically, we show how periodic control may be…
Nonadiabatic Dynamics of a Dissipative Two-level System
Canran Xu, Amrit Poudel, Maxim G. Vavilov
We study the dynamics of a two-level system described by a slowly varying Hamiltonian and weakly coupled to the Ohmic environment. We follow the Bloch--Redfield perturbative approa…
Majorana Flat Bands in s-Wave Gapless Topological Superconductors
Shusa Deng, Gerardo Ortiz, Amrit Poudel +1
We demonstrate how the non-trivial interplay between spin-orbit coupling and nodeless -wave superconductivity can drive a fully gapped two-band topological insulator into a time…
Electromagnetic properties of thin metallic films
Luke S. Langsjoen, Amrit Poudel, Maxim G. Vavilov +1
We compute the electromagnetic fluctuations due to evanescent-wave Johnson noise in the vicinity of a thin conducting film, such as a metallic gate or a 2-dimensional electron gas.…
Relaxation in quantum dots due to evanescent-wave Johnson noise from a metallic backgate
Amrit Poudel, Luke Langsjoen, Maxim Vavilov +1
We present our study of decoherence in charge (spin) qubits due to evanescent-wave Johnson noise (EWJN) in a laterally coupled double quantum dot (single quantum dot). The high den…
Qubit relaxation from evanescent-wave Johnson noise
Luke S. Langsjoen, Amrit Poudel, Maxim G. Vavilov +1
In many quantum computer architectures, the qubits are in close proximity to metallic device elements. Metals have a high density of photon modes, and the fields spill out of the b…
Quantum efficiency of a microwave photon detector based on a current-biased Josephson junction
Amrit Poudel, Robert McDermott, Maxim G. Vavilov
We analyze the quantum efficiency of a microwave photon detector based on a current-biased Josephson junction. We consider the Jaynes-Cummings Hamiltonian to describe coupling betw…
Effect of Ohmic environment on optimally controlled flux-biased phase qubit
Amrit Poudel, Maxim G. Vavilov
We analyze the effect of environment on the gate operation of flux-biased phase qubits. We employ the master equation for a reduced density matrix of the qubit system coupled to an…
